1. what is a relationship between
OLCI water-leaving reflectance (https://sentinel.esa.int/web/sentinel/technical-guides/sentinel-3-olci/level-2/products-description ) (ESA’s level-2 product)
Remote Sensing Reflectance (Rrs; sr-1) (NASA’s level-2 product)?
2. Does your group plan to generate and to access the OLCI level-2 data to oceancolor community?
The difference between water leaving reflectance (rho_w) and remote sensing reflectance (Rrs) is a factor of PI.
Yes, we do plan to generate and make available OLCI level-2 data processed consistently with all of the missions we support.
We are currently in the process of evaluating the vicarious calibration for both OLCI on both the S3A and S3B platforms. Once we have verified our calibration, we will initiate the processing of OLCI to Level-2 and Level-3.
Assuming a Lambertian surface, yes water leaving reflectance (R) would be Rrs*pi. For a comprehensive answer, see:
