satpy.readers.seviri_l1b_icare module

Interface to SEVIRI L1B data from ICARE (Lille).

Introduction

The seviri_l1b_icare reader reads MSG-SEVIRI L1.5 image data in HDF format that has been produced by the ICARE Data and Services Center Data can be accessed via: http://www.icare.univ-lille1.fr

Each SEVIRI timeslot comes as 12 HDF files, one per band. Only those bands that are of interest need to be passed to the reader. Others can be ignored. Filenames follow the format: GEO_L1B-MSG1_YYYY-MM-DDTHH-MM-SS_G_CHANN_VX-XX.hdf Where: YYYY, MM, DD, HH, MM, SS specify the timeslot starting time. CHANN is the channel (i.e: HRV, IR016, WV073, etc) VX-XX is the processing version number

Example:

Here is an example how to read the data in satpy:

from satpy import Scene
import glob

filenames = glob.glob('data/*2019-03-01T12-00-00*.hdf')
scn = Scene(filenames=filenames, reader='seviri_l1b_icare')
scn.load(['VIS006', 'IR_108'])
print(scn['IR_108'])

Output:

<xarray.DataArray 'array-a1d52b7e19ec5a875e2f038df5b60d7e' (y: 3712, x: 3712)>
