AbstractThe present investigation evaluates surface reflectance retrieved from Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) and Compact Airborne Spectrographic Imager (casiTM) data using the CAM5S and MODTRAN4 atmospheric radiative transfer (RT) codes. The retrieved surface reflectances were compared with ground-based reflectances acquired with a GER3700TM spectroradiometer for a playa and canola target. The results showed that the best overall performance was achieved with MODTRAN4. Major differences occur in the stronger gas absorption regions. At wavelengths unaffected by strong gaseous absorption, the performance was similar for both RT codes even though CAM5S has an execution time that is about about 50 times faster than that of MODTRAN4.
