Re: OLCI Vicarious Calibration Coefficients

Hi Sean,

Thanks for providing the SVC gains for OLCI S3A. Would the gains for S3B be all ones?

BRDF correction l2gen

I'm processing S3 OLCI data from level 1 to level 2 using l2gen. I'm wondering if L2 outputs are corrected for BRDF effects? Is there a way to change this parameter?

Thanks,
Anna

l2gen SWIR/NIR method with OLCI

Thanks Sean. Would this be correct? Do I need all four NIR/SWIR wavelengths for aer_corr=-9 or just two wavelengths?aer_wave_short=779aer_wave_long=865aer_swir_short=940 aer_swir_long=1012 (realized it is not OLCI band 1020 after reading this post: https://oceancolor.gsfc.nasa.gov/forum/oceancolor/t...

l2gen SWIR/NIR method with OLCI

Hi,I am wondering if anyone has used l2gen with Wang's NIR/SWIR switching method with OLCI data? I've tried:         'aer_opt= -9',    'aer_swir_short = Oa20_radiance.nc',          'aer_swir_long = Oa21_radiance....
