satpy.readers.slstr_l1b module

SLSTR L1b reader.

class satpy.readers.slstr_l1b.NCSLSTR1B(filename, filename_info, filetype_info, user_calibration=None)[source]

Bases: BaseFileHandler

Filehandler for l1 SLSTR data.

By default, the calibration factors recommended by EUMETSAT are applied. This is required as the SLSTR VIS channels are producing slightly incorrect radiances that require adjustment. Satpy uses the radiance corrections in S3.PN-SLSTR-L1.08, checked 11/03/2022. User-supplied coefficients can be passed via the user_calibration kwarg This should be a dict of channel names (such as S1_nadir, S8_oblique).

For example:

calib_dict = {'S1_nadir': 1.12}
scene = satpy.Scene(filenames,
                    reader='slstr-l1b',
                    reader_kwargs={'user_calib': calib_dict})

Will multiply S1 nadir radiances by 1.12.

Initialize the SLSTR l1 data filehandler.
