Hello,
I noticed in variables for 'add_offset: 0.05' and 'scale_factor: 2.0E-6' in the Rrs Band_attributes for S3A/S3B EFR Ocean Color (OC) product (OLCIS3B_L2_EFR_OC) from OB.DAAC. Are these automatically applied to the .nc file, or do I need to scale and add the factor to the rrs measurements in the file to get the correct rrs?
For example, Rrs_560 at an area in a S3A scene is 0.00738 sr^-1. Should I multiply this by 2.0E-6 and add 0.05 to it to get the correct Rrs? That seems wrong...
I also saw these scale_factors and add_offset in VIIRS NPP and NOAA-20 Ocean Color (OC) products.
Thanks!
Best,
Sami
