When using "aer_opt=-8" and "taua=" to do the atmospheric correction of GOCI and VIIRS, The Rrs longer than 700 nm (e.g. Rrs_745) does not have values for these two sensors. Can you tell me how to solve this problem? I need the Rrs products in the NIR bands.
I have checked this method (Multi-scattering with fixed aerosol optical thickness) using the GUI of SeaDAS. It also has the same prblem with VIIRS or GOCI. Thank you very much.
In my opinion, the atmospheric correction method (aer_opt=-8" and "taua=) does not need the assumptions of water (like the water-leaving reflectance of NIR band is zero). However, I find that when I set "ave_short=745 aer_wave_long=862", these two bands do not have Rrs value. Can you tell me the reason? Thank you very much.
aer_opt=-8(user input taua), you can make l2gen generate Rrs for all but the longest wavelength if you set (e.g. MODIS):
The code doesn't use these values when
aer_opt=-8is selected, but by setting them the code will output Rrs for the default bands (for MODIS, 748 and 869nm).
In fact, you can set it to any band above 600nm that you do not desire Rrs output.
Thank you very much. It really helps. In the next step, I will test the performance of the atmospheric correction of VIIRS using SeaDAS in several inland waters.
