satpy.readers.msi_safe module

SAFE MSI L1C reader.

The MSI data has a special value for saturated pixels. By default, these pixels are set to np.inf, but for some applications it might be desirable to have these pixels left untouched. For this case, the mask_saturated flag is available in the reader, and can be toggled with reader_kwargs upon Scene creation:

scene = satpy.Scene(filenames,
                    reader='msi_safe',
                    reader_kwargs={'mask_saturated': False})
scene.load(['B01'])
