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.
