Dear Dr. Middleton,

This email is in response to the message sent to the CEOS/WGCV community concerning the planned termination of Hyperion data acquisition.

My team has been carrying out several studies related to mapping the structure and seasonal changes of boreal forests using Hyperion data.

Currently, Hyperion offers the only possibility to analyze time series of spectral (not multispectral!) data for large forest areas. Based on Hyperion data, we have recently published a paper on the sensitivity of narrowband vegetation indices to boreal forest LAI, reflectance seasonality and species composition (Heiskanen et al. 2013, attached).

In addition, we are in the process of preparing a manuscript which links a seasonal time series of Hyperion data to seasonal changes in forest structure through radiative transfer modeling.

The goal of my team’s current projects is to understand the driving factors of boreal forest reflectance seasonality. Currently, we have funding from national sources (e.g. Academy of Finland) and plan to continue field work during the growing seasons in 2015 and 2016.

Having access to data from the Hyperion sensor in 2015/2016 would be extremely valuable for us.

Best regards, Miina Rautiainen

Dear Dr. Mottus,

Thank you for your very compelling letter. We will include it in our folder of letters of support. My team and I will be making the case to NASA HQ in one week from now to request a one year extension to the EO-1 mission, for Earth-viewing collections, which would enable growing season collections in 2015 and 2016. The SZA at the time of the observations will be becoming lower over that time period as the overpass time moves toward 8am. We will be highly interested in the datasets acquired for you project, especially as one of several special studies that could contribute to our understanding of how the increasing shadow cast by the forest will impact the interpretation of the physiological measurements that your ground team collects.

We wish you the very best in your study, and please keep me informed.

Regards, Betsy Middleton

Dear Dr. Middleton,

I am writing in response to the e-mail regarding the planned cessation of EO-1 data acquisition. Our research on remote sensing of boreal forest functioning would be dramatically and negatively affected by the planned termination of the EO-1 satellite with the Hyperion sensor aboard. Despite the old age of the sensor and other known limitations of Hyperion imagery, it is a unique and extremely valuable source of information for improving the techniques of remote sensing of forest physiology.

We are currently finalizing a manuscript relating Hyperion data from 2009-2011 with shoot chamber measurements of photosynthesis and light use efficiency. We planning to continue this work and relate the photosynthetic processes to in-situ needle spectra. Currently, the project under my supervision has funding from the Academy of Finland until 2018. We are planning airborne imaging spectroscopy campaigns for forthcoming summers. Although having coarser spatial resolution and lower signal to noise ratio, Hyperion data would supplement the temporally limited airborne acquisitions and allow to scale our results both temporally and spatially. Currently, there is no alternative hyperspectral data source which would allow us to achieve this.

The activities related to remote measurement of the functioning of boreal forests, including the efforts carried out at the long-running SMEAR II site in Hyytiälä, Finland, would be seriously hindered by the future unavailability of Hyperion imagery.

Subject: Re: Notice: EO-1 termination plan

Hello Betsy Middleton - thank you for providing this very informative notice on EO-1 potential end-of-life activities. As head of the Lunar Calibration project at USGS (ROLO), I am very interested in using Hyperion acquisitions of the Moon. To date, I have not managed to get a project funded that would cover the analysis of Hyperion lunar data, but I am hopeful this will happen in FY-16.

The existing Hyperion lunar dataset can be useful to me for constraining the reflectance of the Moon spectrally. However, an expanded range of phase angles coverage by Hyperion would indeed provide an invaluable dataset of lunar spectral observations for potential improvement of lunar calibration capabilities. I strongly support the use of Hyperion for this purpose.

Please let me know if you have any questions, or if you would like to discuss this further.

Thanks again,

Subject: Re: Request for EO-1 and Hyperion support letter

Dear Stuart,

This will help a lot - thank you for this. Do you see any opportunities for the future to get orthorectified at-ground reflectance or for collaboration? I have 'only' found Level2-atm but not Level2-atm/geo - maybe I have overlooked something. We still try to recover the orbit for the retrieval of L2-atm/geo, but it appears that this is too coarse using only the image/product corners. Mostly, we use our own chain (alpha status) as briefly described here: http://www.earsel.org/symposia/2014-symposium-Warsaw/pdf_proceedings/EARSeL-Symposium-2014_3_1_rogass.pdf ,but this is also too coarse (geometry).

Hyperion is for us not only a testbed for the EnMAP mission - it is also our primary spaceborne tool for soil and especially geological applications. The spectral performance is for most purposes more than sufficient, e.g. we are able to verifiable detect Rare Earth Elements. But for some applications it is absolutely necessary to use multitemporal, orthorectified at-ground reflectance.
However, I'd like to take this opportunity to sincerely thank you and the whole Hyperion team for giving other researchers the opportunity to use Hyperion, its products and archive services free of charge.

Have a lovely weekend

Subject: RE: Request for EO-1 and Hyperion support letter

Dear Stuart,

I'm sorry to hear about this sad situation regarding the possible ending of the EO-1 mission. Over the last years, my colleagues and I have been working quite a lot with Hyperion data, as it's the only civilian spaceborne spectrometer covering also the SWIR range. And ending this mission would be a serious loss! So please let my colleagues (in CC) and me know how we can support you and the EO-1 mission!
Speaking for the team Applied Spectroscopy of the DLR, please find below a few notes on how Hyperion is and has been used.Within all these activities, Hyperion could be applied successful - after putting some efforts in eliminating all the data defects (bad bands, smile), and after atmospheric correction using ATCOR. Within all these activities, the scientific objectives could exclusively been carried out thanks to the SWIR capabilities of Hyperion, which neither CHRIS/Proba nor HICO as also available spaceborne IS sensors offer.

  • Usage of Hyperion for the simulation of EnMAP and Sentinel 2, especially for the development and testing of the ATCOR atmospheric correction package developed within DLR by Rudolf Richter.
  • Biodiversity and land degradation mapping in Namibia, Hyperion in addition to airborne hyperspectral data and CHRIS/Proba data (BIOTA project, 2 PhD and 1 MSc thesis at DLR)
  • Geological mapping in China (ChiCo project on mapping coal fires in China)
  • Development of a multiple endmember spectral mixture analysis (MESMA) for dryland degradation. Hyperion and simulated EnMAP data was used in order to evaluate the upscaling from airborne to typical spaceborne sensor characteristics (spatial resolution, SNR). (PhD thesis at DLR)
  • Using spaceborne hyperspectral data for spectral cross-calibration of multispectral sensors.
This current file of work will will be presented in this years IGARSS session I.8: Invited Sessions: Calibration And Validation, Inter-Calibration And Coming To Terms With Terminology. To quote the abstract (Using spaceborne hyperspectral data for spectral cross-calibration of multispectral sensors, M. Bachmann, T. Müller): Within this oral presentation, a methodology for the cross-calibration of multispectral sensors based on spaceborne hyperspectral, and its practical implementation for a consistent re-processing of 30+ years of NOAA AVHRR data are shown. For the development, a large variety of HYPERION images including typical surface spectral signatures for Western, Central, South and Eastern Europe, Scandinavia, as well as Northern Africa are used, also covering different seasonal and phenological conditions. This extensive database of hyperspectral imagery is then used to simulate the spectral responses of various multispectral sensors. Extending the approach from STEVEN et al. [2003, 2007], statistically robust models are developed in order to derive intercalibration factors for the specific sensor spectral responses. By applying these factors, differences caused by the spectral response functions of multispectral sensors can be reduced resulting in an increased consistency in multi-sensoral time series. This finding underpins the need for spaceborne imaging spectrometers such as HYPERION, the upcoming EnMAP and HISUI, and dedicated missions such as the proposed TRUTHS, which can be used as a direct reference for spectral and radiometric cross-calibration.

I hope this brief list of activities is helpful, and I keep my fingers crossed that EO-1 will be active for many more years!

Best regards from DLR,

EO-1 Letter of Support

Dear Stu,

I´m doing a cumulated PhD study and it is planned to use Hyperion data for my third paper. I used a spectrometer to measure the reflectance of West African rangeland vegetation and to link it to the vegetation´s forage quality and quantity. Originally we were hoping to conduct a hyperspectral flight campaign in our research area but until now we were not able to arrange this within our project. Therefore we were really glad to have Hyperion as an alternative source for hyperspectral data. It is foreseen to apply my models for forage quality and quantity on Hyperion data to predict rangeland forage provision in our study area. I made some first attempts to preprocess the images and use ‘multiple endmember spectral mixture analysis’ to detect areas of rangeland and then apply my models. So far the results seem to be quite promising.

Since I have not yet an idea what I´m going to do after my PhD I fear I cannot answer your question regarding a use of EO-1 beyond 2015. But so far we are really glad to have the data for free; this has been a great relief.

Kind regards,

Dear Sir or Madam,
Letter of support for the continuation of EO-1 Hyperion operations

As the leader of the Remote Sensing section of the GFZ Potsdam and the Principal Investigator of the EnMAP imaging spectroscopy mission, I would like to express our great interest in the continuation of EO-1 Hyperion acquisitions beyond 2015.

Since Hyperion is the only operating satellite system able to provide data comparable to EnMAP (launch scheduled for 2018), it has become a critical data source for a number of our preparatory activities, including:

  • Development of pre-processing methods for noise reduction, cloud screening and atmospheric correction. Hyperion is being used as a testbench for the implementation and testing of those methods.
  • Earth surface remote sensing observations of geoarchives and landscape formations in southern Africa linked with paleo-environmental research. Particularly of interest is the study of soil erosion, deposition and degradation processes which will allow further development of knowledge for the impact of land use, land use changes and climate changes on the landscape.
  • Assessment of land/water resource management in semi-arid NE Brazil, which implies the monitoring of temporal and spatial dynamics of the eutrophication process. Satellite data acquisition and concurrent monthly field campaigns are currently running (mid 2014 till mid 2015) and may be extended beyond 2015 due to long-term cooperation with universities/institutions in land/water resources management in Ceará/Brazil.
  • Mineral mapping with the EnGeoMAP (EnMAP Geological Mapper) model. We especially test SNR dependent detection limits for mineral mapping from simulated EnMAP data and “real world” EO-1 Hyperion data. This involves the further development, calibration and validation of mineral and geological mapping tools for EnMAP e.g. for different geological environments and deposit types.

Letter of support of continuation of funding of the EO-1 mission

Dear Stu,

To whom it may concern. As one of the PIs of the ICDP/NSF/NERC/DFG funded international Hominin Sites and Paleolakes Drilling Project (HSPDP) we are currently working towards a calibration of chemical climate proxies from long (<278 m) sediment cores. We have identified hyperspectral scanning of both source rocks and sediments, together with hyperspectral satellite imagary as a promissing new tool to better understand the processes linking climate with weathering, erosion and sedimentation in largely inaccessible areas such as the Suguta Valley (Kenya) and the Chew Bahir (Ethiopia).

In this project, we are in the middle of the calibration of the new technique. So far, we could evaluate some EO-1 Hyperion scenes provided by you and obtained promissing results. However, we have previously waived an aquisition of larger parts of sedimentary basins, since we wanted to wait for the completion of the calibration work on groundtruth samples. It is therefore important that the satellite will remain available to be utilized by us to continue acquiring data in support of the proposed work through about April 2018.

Kind regards,

EO-1 Letter of Support

26 March 2015

To Whom It May Concern:

I write in support of the EO-1 mission extension through 2016 to enable hyperspectral cryospheric research to continue through the 2016 winter and spring seasons. Hyperspectral imagery acquired with the EO-1 Hyperion sensor has been, and continues to be critical Earth Observation data source for studying snow and ice surface properties.

Since coming to the Cryospheric Sciences Laboratory at NASA/GSFC as a NASA Postdoctoral Program Fellow, I have been collaborating with EO-1 Science Team members on using EO-1 Hyperion imagery to study snow properties in the near boreal zone of northern Minnesota, and Great Lakes ice in northern Wisconsin and northern Michigan. This work during the 2015 winter and spring seasons has involved collecting coincident ground-based spectroscopy snow and ice measurements with a field spectrometer during or near EO-1 Hyperion overpasses. I am pleased to report that there have been a number of successful EO-1 Hyperion acquisitions during field data collection campaigns.

In my view, extending the EO-1 mission through 2016 leverages existing Earth Observation resources and infrastructure that are otherwise not readily available for advancing current and near-term cryospheric research. At the same time, extending the EO-1 mission could support focused study on possible future mission/measurement concepts during a key time period when initial planning is underway for the next decadal survey.

EO-1 Letter of Support

To: Daniel Mandl, NASA/GSFC

With this letter we would like to express our appreciation of the EO-1 mission and the SensorWeb Experiment. Satellite data acquired by EO-1 instruments were of great importance in activities carried out by the Space Research Institute NASA-NSAU and the UN-SPIDER Regional Support Office in the Ukraine. The data were used both for operational purposes to monitor natural disasters, such as floods, and research purposes for land monitoring and vegetation state assessment.

For example, during the winter-spring period 2010 that was characterized in Ukraine by large amount of snow and ice on rivers and posed a high threat of floods were acquired 3 EO-1 images that were processed and delived to local authorities. It is worth noting that the use of SensorWeb technologies ensured a timely delivery of data and products to the end-users' We would to express our strong support for the continuation of the EO-1 mission and looking forward for close collaboration with NASA team!

Dear Stu,

I provide with great pleasure and appreciation this note of commendation for EO-1 and the good many people "behind the scenes" who make the system work.

As a practitioner in radar remote sensing applications for many years I have only been exposed to EO-1 quite recently within the context of project work associated with the CEOS/GEO Caribbean Satellite Disaster Pilot. There are three items that I would like to highlight among the outstanding qualities of EO-1.

I appreciate the ease-of-access to the system from the user perspective, including the on-line data acquisition programming, notification and delivery services. I have found the timely and competent support that you and your team members have provided very reassuring.

I was impressed with the fine data we have received to-date. As a matter of fact, I found the EO-1 ALI and Canadian Radarsat SAR data complementary in very good and very helpful ways, both in terms of resolution as well as for feature recognition and verification purposes.

Last, but not least, I would like to acknowledge the generosity with which the EO data is provided by the United States and NASA for science and research and development projects in many parts of the world. This is an invaluable and much appreciated contribution to collaborative environmental research activities.

Wishing you and your colleagues the very best of success for the continuation of the EO-1 mission.

Dr. Elizabeth Middleton Hydrospheric and Biospheric Sciences Laboratory NASA Goddard Space Fight Center Greenbelt, MD 20771 Dear Dr. Middleton:

Thank you for the support NASA has provided to map the aggressive and rapidly spreading invasive tree, Chinese tallow. I would also like to acknowledge Dr. Stuart Frye who is providing outstanding collection support for this mapping project.

The tallow mapping supports the Toledo Bend Project Joint Operations and relies on the successful collection of EO-1 Hyperion sensor data that covers the fairly extensive forest and light-developed areas surrounding the Toledo Bend Reservoir on the border of Louisiana and Texas. Tallow detection requires high-spectral resolution data collected within the fall when senescing tallow turns a color that is unique within the native landscape. Even though the senescent timing, pervasive cloud cover, and collection frequency hampered the full and time-appropriate coverage of the target region, the successful EO-1 Hyperion and ALI collections over the last few months have provided a well-populated Hyperion and ALI database for determining the ability to map tallow in this area.

The requesting agency, the Toledo Bend Project Joint Operations staffed by the Sabine River Authority of Texas and the Sabine River Authority of Louisiana, is responsible for the operation of the Reservoir and surrounding land areas. Their interest in our mapping the tallow was based on published works describing our mapping of Chinese tallow with Hyperion image data as part of the NASA EO-1 Science Validation Team. Those works provided the first regional mapping of Chinese tallow occurrences and linked those occurrences to landcover and landuse (cultivation, silviculture) maps created with Landsat Thematic Mapper satellite data.

If successful, this project will offer the first application of these Chinese tallow mapping capabilities operationally.

EO-1 Mission and NOAA


First, I would like to thank you for inviting me to the EO-1 symposium last year. As I stated during my presentation, EO-1 turns out to be a very important mission for NOAA because it provides unique capabilities for us in the following areas:

1) Calibration/validation of operational satellite instruments. The EO-1/Hyperion data at several cal/val sites have been used for site spectral characterization, resolving inter-satellite biases due to spectral response differences, and to study atmospheric absorption features at different sites.

2) Hyperion data has been instrumental for the international inter-satellite calibration study at the Dome C site under the auspice of CEOS. Continued acquisition of Hyperion data at the site will allow us to further reduce uncertainties in the spectral BRDF of the site, and ultimately establish this site as a community radiometric standard for all space agencies including NOAA and NASA. This will be a great contribution to climate studies because Dome C is one of the few places on Earth that is relatively stable, with little atmospheric effects and uncertainties associated.

3) Hyperion data is very useful for NOAA's near-future programs such as GOES-R and JPSS. For GOES-R which will be launched in the 2015 time frame, we will need Hyperion data to characterize the cal/val site in the Sonora desert, Mexico, as well as acquisitions of Deep Convective Cloud scenes to study their spectral characteristics. For JPSS which will be launched later this year or early next year, Hyperion data will be critical for understanding and resolving the biases between VIIRS on NPP and its heritage instrument AVHRR, since they have very different spectral response functions.

4) Finally, I would like to add that the EO-1/Hyperion represents a unique national asset that currently does not have a replacement. While other countries are developing similar capabilities, it is important to continue to show the US leadership in hyperspectral remote sensing.

I look forward to getting more EO-1/Hyperion data to help NOAA with the operational satellite programs.

Thank you.

EO-1 10th Anniversary Celebration Invitation

Dear Dan, Steve and Betsy

Congratulations to you and the entire EO-1 team for reaching this truly memorable milestone. What a remarkable success this technology demonstration mission it has been?! I recently read another short article about another formation flying experiment with sub-orbital observatories. The number of first of a kind experiments done by this mission must be at historical record level. Unfortunately, some of our colleagues do not remember and acknowledge that that A-train is a reality because of the knowledge we gained from EO-1 and Landsat formation flight. Please convey my best regards and heartfelt congratulations to the entire team and participants at the 10th Anniversary celebration. I will unfortunately miss it because I now work on the other side of Atlantic in Europe.

Best regards,

Subject: RE: Assistance to Namibia

NASA provided support through a few means. Under a CEOS activity, Stu Frye and Dan Mandl were using EO-1 as part of a flood warning pilot; this activity also ties into a GEO Task (Task DI-09-02b - Regional End-to-End Disaster Management Applications).

Applied Sciences provided some funding this year to Frye/Mandl to continue their support of this activity while we're waiting on a formal proposal (I'm checking with Goodman whether that proposal arrived). Applied Sciences funded a Global Flood and Landslide project in ROSES-2007 (PI: Policelli and Adler). which uses TRMM data and hydrological model for daily estimates of flood area. The scale is much coarser than the EO-1 data, obviously. Though, I believe Policelli has been working with Frye/Mandl.

In addition, since Policelli is also a Co-I on the ROSES-2007 SERVIR-Africa project, there are linkages and ties to SERVIR-Africa. In addition, Robert Brackenridge (Dartmouth Flood Observatory, which is moving to Univ. of Colorado) is on the SERVIR-Africa team so there's a likely connection there (assumed rather than confirmed at this point).

I will forward the original email to Frye and Policelli to ask them for more background.

Hi Stu,

Before anything, I just want to say thanks for the continued support with the Chile imagery.

We’ve also just created a series of requests under the campaign entitled “Fires in Peten, Guatemala” where there have been persistent fires near some roads in protected areas.  Around this time of year, the smoke plumes from this and surrounding areas have even reached the southern US and also pose significant threats to human health.  See http://www.nasa.gov/mission_pages/servir/smog_blog.html

We’ve been downloading as many historic ALI images as we can, but there’s currently not coverage in some of the Peten.  As I tried to note in the requests, the highest priority of the three is Laguna del Tigre, so hopefully we’ll be able to focus on that area first.

Thanks again for the support.

All the best,

Dear Stuart:

*I am Chuqun Chen a research professor on ocean colour remote sensing, working at South China Sea Institute of Oceanology, Chinese Academy of Sciences. I am a user of not only the NASA's ocean color satellite data, but also NASA's EO-1 Hyperion data. I write you the letter to express my appreciation to all the staffs working on the data service. The EO-1 Hyperion data are the only available hyperspectral satellite data to my research group. Two years ago, based on the Hyperion data, we developed an improved algorithm for retrieval of chlorophyll concentration, the fluorescence line area (FLA) algorithm, which employs all the bands covering the chlorophyll's fluorescence peak. The improved algorithm is better than the FLH (fluorescence line height) algorithm, and could be used for redtide or algae blooms with chlorophyll concentration higher than 5ug/L. Recently, we are working on experiment for detection of heavy metal concentration from Hyperiion data. The Hyperion data are very important for our research.

*NASA has been the pioneer on satellite sensor development since 1970s. We are looking forward to your new EO-1 hyperspectral satellite sensors. If the swath of the future hyperspectral satellite data could be increased to 60 or 100 km, I think the hyperspectral satellite data will play a key role in detection of water quality.
