class satpy.readers.seviri_l2_grib.SeviriL2GribFileHandler(filename, filename_info, filetype_info)[source]

Bases: BaseFileHandler

Reader class for SEVIRI L2 products in GRIB format.

Read the global attributes and prepare for dataset reading.

property end_time: Return the sensing end time.

get_area_def(dataset_id)[source]: Return the area definition for a dataset.

get_dataset(dataset_id, dataset_info)[source]

Get dataset using the parameter_number key in dataset_info.

In a previous version of the reader, the attributes (nrows, ncols, ssp_lon) and projection information (pdict and area_dict) were computed while initializing the file handler. Also the code would break out from the While-loop below as soon as the correct parameter_number was found. This has now been revised becasue the reader would sometimes give corrupt information about the number of messages in the file and the dataset dimensions within a given message if the file was only partly read (not looping over all messages) in an earlier instance.

property start_time: Return the sensing start time.
