Sentinel 2 L2A band data not in range 0-1

Hi @david.p,

It shouldn’t be a mistake. Some Sentinel-2 data (both L1C and L2A) actually has reflectance values greater than 1. This can happen for some very bright surfaces such as snow, some clouds or some bright building roofs.

If you would like to verify that yourself, I suggest downloading an original product from ESA Scihub for the same area and the same timestamp and comparing the values.
