MCI OLCI processing parameters

[jvaldezch]

Hi community,

I'm processing some Sentinel-3 OLCI images to obtain data to produce an MCI product to detect sargassum in the Caribbean but I'm encontring sometimes that some swaths have too much saturation or brightness. I have been trying to use different parameters but image still have some saturation in the Gulf of Mexico like in the next image.

Default parameters:
l2gen l2prod=Rrs_681,Rrs_709,Rrs_754 ifile=S3B_OL_1_EFR____20250728T152057_20250728T152357_20250729T163645_0179_109_182_2520_ESA_O_NT_004.SEN3/xfdumanifest.xml ofile=DEFAULT_PROCESSING.nc resolution=300 cloud_thresh=0.052

After reading some of the parameters that l2gen accepts I come up with this parameters:

l2gen l2prod=Rrs_681,Rrs_709,Rrs_754 ifile=S3B_OL_1_EFR____20250728T152057_20250728T152357_20250729T163645_0179_109_182_2520_ESA_O_NT_004.SEN3/xfdumanifest.xml ofile=PARAMS_PROCESSING.nc resolution=300 cloud_thresh=0.052 gas_opt=8 proc_ocean=2 glint_opt=2 oxaband_opt=1 brdf_opt=1 atrem_opt=1 atrem_full=1 maskland=on maskbath=on maskglint=on

Now the saturation goes but I'm losing some value data. Any help would be appreciated.
