satpy.readers.seadas_l2 module

Reader for SEADAS L2 products.

This reader currently only supports MODIS and VIIRS Chlorophyll A from SEADAS.

The reader includes an additional keyword argument apply_quality_flags which can be used to mask out low-quality pixels based on quality flags contained in the file (l2_flags). This option defaults to False, but when set to True the “CHLWARN” pixels of the l2_flags variable are masked out. These pixels represent data where the chlorophyll algorithm warned about the quality of the result.

class satpy.readers.seadas_l2.SEADASL2HDFFileHandler(filename, filename_info, filetype_info, apply_quality_flags=False)

Bases: _SEADASL2Base, HDF4FileHandler

Simple handler of SEADAS L2 HDF4 files.

Initialize file handler and determine if data quality flags should be applied.
