Unfortunately, the s2cloudless is meant only for L1C, so it won't work on L2A. There are a few workarounds:
- get access somehow (Sentinel Hub, etc.. ) to L1C data for the same area, run the s2cloudless on that, and copy the classification over
- do a request to Sentinel Hub with the same bounding box and timestamps for downloading pre-calculated CLP and CLM features for cloud probabilities and masks, respectively
The second option is cheaper, since you don't need to download so many things, but the pre-computed CLP/CLM were run on 160m resolution.
According to this document by Sentinel-hub the cirrus band B10 was excluded as it does not contain any "bottom of the atmosphere" information.
Is there a way to use the s2cloudless cloud detector without that band? If yes, how so?
Note: I'm trying to apply the package to a regular sentinel-l2a not acquired through sentinel-2 hub, therefore i dont have access to classification bands. Besides the regular bands, i have access to AOT (Aerosol Optical Thickness), WVP (Water Vapour) and SCL.
Thanks!
