Atmospheric Corrector
Earth imagery is degraded by atmospheric absorption and scattering. The EO-1 mission will provide the first space based test of an AC for increasing the accuracy of surface reflectance estimates.
The 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 .85-1.5 um, bands are selected for optimal correction of high spatial resolution images.
- Correction of surface imagery for atmospheric variability (primarily water vapor)
Ground validation of AC data using selected areas of globe where little surface variation exists but atmospheric variability changes. Also comparison of AC data with radiosondes, and other satellites sounders.
Benefits to Future Missions:
The AC Instrument will provide significant improvements in generating accurate reflectance measurements for land imaging missions.
The algorithms developed will enable more accurate measurement and classification of land resources and better predictive models for land management in the future.
Atmospheric Corrector Optics and Electronics Modules have been successfully integrated and tested together. Detector characterization testing under vacuum and temperature will commence on February 4th.
