how to estimate AOT for sunglint radiance calculation?

by lwk1542 » Wed Mar 17, 2021 12:22 pm America/New_York

According to the code in the “atmocor2.c” and “glint.c” files,the sunglint needs to be computed before aerosol estimating. However, the aerosol optical depth is an input variable for sunglint. In the page (https://oceancolor.gsfc.nasa.gov/docs/o ... b06f5.html), I did not find any function to estimate aerosol optical depth by using Lt and wind speed. So, is there any document or code for teaching estimating AOT for sunglint iteration correction ? THANKS

If you read atmocor2.c and glint.c, you'll see that it's an iterative process. For details, see:

M. Wang and S. Bailey, "Correction of sun glint contamination on the SeaWiFS ocean and atmosphere products," Appl. Opt. 40, 4790-4798 (2001). https://doi.org/10.1364/AO.40.004790
