I have two questions regarding the handling of the radiometric offset for the Sentinel L2A data in SNAP.
- if I activate the option “Add negative radiometric offset” as described in this post ([INFO] Introduction of additional Radiometric Offset in PB04.00 products) , what influence does this have on the calculation of the NDVI for L2A data before PB 04.00 and afterwards?
Will the offset be subtracted for all data?
- if this is not the case, do I have to manually subtract the offset for data processed before PB 04.00 for bands 4 and 8? And if yes, where and how would I do this?
I hope you can help me with this. Thank you very much.
