The MODIS subset problem of l2gen
Hi, We download the MODIS L0 files from ocean color and the L0 files were processed to L1B by SeaDAS 8.1.0. Then the L1B files were processed by l2gen to get the Rayleigh corrected reflectance products. However, we find that the subset function of l2gen (like north=31.8 sourth=30.5 west=119.6 east=1...

How to get the Rayleigh diffuse transmittance Only
Hi, In SeaDAS l2gen, The output products t_sen and t_sol are the Rayleigh-Aerosol diffuse transmittance. We want to obtain the Rayleigh diffuse transmittance only. The t_sen and t_sol are the Rayleigh diffuse transmittance only when we set the "aer_opt=-99" (No aerosol subtraction) ? If no...

SLSTR data
Hi,
I want to get the rayleigh corrected reflectance product of SLSTR. Can I ask whether SeaDAS has the plan to add the module of SLSTR?

About the calculation of relative azimuth angle
Hi, We want to do the atmospheric correction of OLCI images using the aerosol tables in SeaDAS. One step, we need to calculate the relative azimuth angle of each pixel and then obtain the aerosol properties of the aerosol tables in the matching relative azimuth angle. How can I ...

The equation of SS aerosol reflectance to MS aerosol reflectance
Hi?We want to convert the OLCI SS aerosol reflectance to MS aerosol reflectance using the equation in aerosol.c as follows.lnrhoas = log(rhoas[iw]*aeroob(sensorID,iw,cf,wv)) rhoa[iw] = exp(a + b*lnrhoas + c*lnrhoas*lnrhoas);I have a few questions.(1) for the OLCI images, can I set aeroob(senso...

Hi, gnwiii
I think it is blocked by the website beacuse I cannot download the data using windows 10. If I use the VPN, I can download the data and process the images.
Thank you very much.
