satpy.readers.gerb_l2_hr_h5 module

GERB L2 HR HDF5 reader.

Introduction

A reader for the Top of Atmosphere outgoing fluxes from the Geostationary Earth Radiation Budget instrument aboard the Meteosat Second Generation satellites.

Reader Arguments

Some arguments can be provided to the reader to change its behaviour. These are provided through the Scene instantiation, eg:

scn = Scene(filenames=filenames, reader="gerb_l2_hr_h5", reader_kwargs={"area": "msg_seviri_fes_9km"})

class satpy.readers.gerb_l2_hr_h5.GERB_HR_FileHandler(filename, filename_info, filetype_info, area=None)[source]

Bases: HDF5FileHandler

File handler for GERB L2 High Resolution H5 files.

Overriding the ``area``

By default, the GERB HR reader looks at the attribute “Geolocation/attr/Nominal Satellite Longitude (degrees)” for selecting the area definition. This data is not available for the GERB-like products however, so you may need to override it with the area argument:

scene = satpy.Scene(filenames, reader="gerb_l2_hr_h5",
                               area="msg_seviri_fes_9km")

Initialize the reader.

__init__(filename, filename_info, filetype_info, area=None)[source]: Initialize the reader.

property end_time: Get end time.

get_area_def(dsid)[source]: Area definition for the GERB product.

get_dataset(ds_id, ds_info)[source]: Read a HDF5 file into an xarray DataArray.

property start_time: Get start time.

satpy.readers.gerb_l2_hr_h5.gerb_get_dataset(ds, ds_info)[source]

Load a GERB dataset in memory from a HDF5 file or HDF5FileHandler.

The routine takes into account the quantisation factor and fill values.
