EO-1 Letters of Communication  

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!

Best regards,

Nataliia Kussul

To: Frye, Stuart W. (GSFC)
Subject: RE: EO-1 letter of support


In my discussions with the SumbandillaSat program of South Africa, the calibration team voiced strong support for the use of EO-1 for cross calibration of their system. They view the hyperspectral data, with its spectral flexibility, as an important tool and were asking about further coordinated collections.

Subject: Re: EO-1 letter of support

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.

EO-1 Letter of Support

Dear Earth Observing-1 Extended Mission,

On behalf of Department of National Park, Wildlife and Plant Conservation (DNP; Http://www.dnp.go.th) and Hydro and Agro Informatics Institute (HAII; Http://www.haii.or.th), we would like to thank you very much to Earth Observing One (EO-1) Extended Mission for its useful and helpful supporting data and information for Thailand Fire and Flood SensorWeb through helps of Stuart Frye, Steve Chien, David Mclaren and Daniel Tran.

The Thailand Fire and Flood SensorWeb are providing Thailand much better information of those affected areas in order to assess more efficient tasks to appropriated areas.

We wish EO-1 team, NASA will continue supporting us both current extended mission and consider to support us in its future missions.

We are very much appreciate for your great supports:-).

Thank you very much:-). Sincerely Yours, Veerachai Tanpipat

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 began imaging Saturday morning

Hi Stuart,

This is good news. EO-1 is a huge success story for NASA. And the new concentrated system management and data acquisition approaches instituted last year are making the very best use of this precious sensor. I just want you and the whole team to know that your efforts are greatly appreciated by the science community.

Earth Observing 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,


Assistance to Namibia

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.

Bests, Lawrence

I just wanted to show you an example (below) of how important the work Goddard is doing in terms of Sensor Web as used by SERVIR at CATHALAC.  Sensor Web has become critical to disaster and environmental management, such as to address the current fires in the Laguna del Tigre Park in Peten, Guatemala.  The fact that application scientists in the developing world can task EO-1 using the system that GSFC created is truly remarkable and a great example of scientific collaboration.  I hope that Sensor Web can continue to develop at GSFC to incorporate new satellites and further serve application scientists around the world.

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,

Pearl River Scene

Sent: Monday, April 19, 2010 3:57 AM To: Frye, Stuart W.
Subject: Re: Pearl River scene

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.
