Cloud masking and scene selection for mosaic #12

Open BaptisteVandecrux opened 3 years ago

BaptisteVandecrux commented 3 years ago

Since we are not removing cloudy pixel from the scenes any more, the selection of scenes stitched in the mosaic is now only based on the scenes’ SZA. In the previous SICE version, cloudy pixels of a scene with low SZA were not used for mosaicking, and the algorithm looked for another scene, of higher SZA, but where cloud-free pixels would be available. This allowed to “rescue” some cloudy pixels using another scene of higher SZA. We could think about a way to keep this behaviour without replacing pixels by NaN.

Would it be about replacing "SZA" by "SZA_CM" in these lines:
