I downloaded the sentinel 2 level C data, and opened it in S2TBX. The data is too large for my computer, so I subset the whole scene and save it as “tif” image. When I open the data again, I find there are totally 17 bands of the data. The optical bands of sentinel 2 level C data should be 13. Can you tell me what is the additional 4 bands? How can I check each band represent what?
The four additional bands must be the solar and azimuth angles, the 13 optical bands are named named B1 to B12 and B8A.
