Hello!
I proccessed OLCI/Sentinel3 with Ploymer.The result is hdf4 file.I opened it with ENVI5.3. I want to get the Rrs,But I think these in hdf4 is Rw.Could you give me a faver in how to get the Rrs?

Thanks for your help in advance!

Dear Kim,

Polymer provides normalized water reflectance (sometimes called water leaving reflectance). Remote-sensing reflectance in sr^-1 can be obtained by dividing by pi. More information here.
