Earth imagery is degraded by atmospheric
absorption and scattering. The New Millennium Program's Earth Observing-1
Mission (EO-1) is providing the first space-based test of an Atmospheric
Corrector (AC) for increasing the accuracy of surface reflectance
estimates.
The Atmospheric Corrector (AC) provides the following capabilities via
a compact and simple bolt on design for future Earth Science, land imaging
missions:
- High spectral, moderate spatial resolution hyperspectral imager
using a wedge filter technology.
- Spectral coverage of .89-1.58 µm. Bands were selected for optimal
correction of high spatial resolution images.
- Correction of surface imagery for atmospheric variability (primarily
water vapor).
The Atmospheric Corrector is applicable
to any scientific or commercial Earth remote sensing mission where atmospheric
absorption due to water vapor or aerosols degrades surface reflectance
measurements. Using the Atmospheric Corrector, instrument measurements
of actual rather than modeled absorption values enables more precise
predictive models to be constructed for remote sensing applications.
The algorithms developed will enable more accurate
measurement and classification of land resources and better models for
land management in the future.
