4.9. FCI L1c NetCDF Reader¶
The FCI Level 1c Reader operates on EUMETSAT Level 1c NetCDF files from the Meteosat Third Generation (MTG) Flexible Combined Imager (FCI) instrument. The FCI L1c reader works off of the input filenames to determine if a file is supported by Geo2Grid. Files usually have the following naming scheme:
W_XX-EUMETSAT-Darmstadt,IMG+SAT,MTI1+FCI-1C-RRAD-FDHSI-FD--CHK-BODY---NC4E_C_EUMT_20170920115515_GTT_DEV_20170920115008_20170920115015_N__T_0072_0001.nc
The FCI L1c reader supports all instrument spectral bands, identified in
Geo2Grid as the products shown in the table below. The
reader can be provided to the main geo2grid.sh script
using the -r option and the reader name fci_l1c_nc.

4.9.1. Command Line Usage¶
usage: geo2grid.sh -r fci_l1c_nc -w <writer> [-h] [--upper-right-corner UPPER_RIGHT_CORNER]
4.9.1.1. FCI L1c NetCDF Reader Loading¶
- --upper-right-corner
Orientation of the data. Data in files is ‘SE’ for South-East which is upside down from the traditional ‘north is up’. This argument defaults to ‘NE’ for North-East and produces the traditional north-up image orientation.
Default: “NE”
Examples:
geo2grid.sh -r fci_l1c_nc -h
geo2grid.sh -r fci_l1c_nc -w geotiff --list-products -f /data/mtg/fci
