Assessment of the Radiometric Calibration Consistency of Reflective Solar Bands between Terra and Aqua MODIS in Upcoming Collection-7 L1B

چکیده
Two MODIS sensors onboard the Terra and Aqua spacecraft have been successfully operating for over twenty-three twenty-one years, respectively, providing worldwide user community with high-quality imagery radiometric Earth observations of land, atmosphere, cryosphere, oceans. This study provides an assessment calibration stability consistency RSB using L1B from upcoming Collection 7 release. Several independent vicarious approaches based on measurements Libya-4 desert, Dome C, DCC, SNO are used to assess at beginning scan, nadir, end scan. Results indicate that both stable within 1% their mission periods. Comparison normalized reflectances either a BRDF model or common reference sensor consistency. results show VIS/NIR bands in good agreement around nadir scan all approaches. For cases varies depending approach but is typically ±2%. The differences observed SWIR slightly larger than bands, which likely due high sensitivity atmospheric conditions relatively electronic crosstalk impact instrument.

On-orbit Performance and Calibration Improvements for the Reflective Solar Bands of Terra and Aqua MODIS
Moderate Resolution Imaging Spectroradiometer (MODIS) is the keystone instrument for NASA’s EOS Terra and Aqua missions, designed to extend and improve heritage sensor measurements and data records of the land, oceans and atmosphere. The reflective solar bands (RSB) of MODIS covering wavelengths from 0.41 μm to 2.2 μm, are calibrated on-orbit using a solar diffuser (SD), with its on-orbit bi-di...
