Calculate Rrs or reflectance from Sentinel-3 radiance

I want to convert the sentinel-3 radiance data to either remote sensing reflectance(Rrs) or reflectance after atmospheric correction. How can I do that ??

Dear suchitra,

SNAP has an athmospheric correction processor in the toolkit that allows to do exactly what you request. Select :
Optical/Thematic Water Processing/C2RCC Processors/OLCI

On the parameter tab of the processor GUI you can select
“Output AC reflectances as rrs instead of rhow”
to retrieve Rrs.

Hope this helps,
Tom
