Cookie-cutter Extraction of geostationary SEVIRI data in coincidence with heliosynchronous satellites (in SEVIRI geometry)
Author(s) : Fabrice DUCOS ( ICARE - LOA )
Written in : C,C++,FORTRAN

Cookie-cutter is a LMD/Icare project whose purpose is to emulate an heliosynchronous satellite with SEVIRI acquisitions. The user defines her heliosynchronous satellite by giving some orbital and swath parameters. The tool then builds an HDF file with SEVIRI data as if they had been viewed by this fictive satellite.

Fis2raw A tool to convert the FIS format (from the SATMOS, at Lannion) into a simple, headerless, raw binary file
Author(s) : Fabrice DUCOS ( ICARE - LOA - Univ. of Lille )
Written in : C

The FIS format is a data format provided in particular by the SATMOS Archivage Center, at Lannion (MSG data at Lannion are archived this way). The program fis2raw converts the FIS format into a raw, headerless, binary file. The number of values and their type may be retrieved while performing the conversion.

Hdf2img Creation an image from a HDF4 SDS
Author(s) : Nicolas PASCAL ( CGTD-ICARE )
Written in : Python

This application creates an image of a 2D HDF4 SDS. It supports different colormaps, min/max thresholding, scaling, fill value filtering...
Many output image formats are also supported.

MSG NATIVE2HDF Extract and save into HDF file IR or VIS MSG data.
Author(s) : Franck Gabarrot (ICARE)
Written in : IDL

This application reads IR or VIS channels in the native MSG format and dump them into a HDF file. It can also compute brightness temperatures for IR channels.

OpenMTP tools Tools for reading and visualizing data in OpenMTP format ( METEOSAT )
Author(s) : Antoinette Alias ( ICARE ), EUMETSAT
Written in : C, FORTRAN, IDL

It contains a list of tools for :
- mapping (lat,lon) coordinates to (i,j) pixel indexes and vice-versa
- data extraction
- data visualisation

POLDER2-MODIS Visualisation of POLDER2 and MODIS data in coincidence
Author(s) : Bruno SIX ( CGTD-ICARE )
Written in : IDL

Tool for comparing visually the POLDER2 and the MODIS coincident data

Parasolascii A simple parser for the POLDER/PARASOL format
Author(s) : Fabrice DUCOS ( ICARE - LOA )
Written in : C

Displays the data from the PARASOL ( and POLDER ) binary files in plain text. You specify the data you want to be displayed, in the order you wish, and they will be extracted into columns (separated by tabulations) in this very order. You are then free to redirect the data into the tool of your choice (a plotter, a data filter, or an hand-made program). Of course, calls to parasolascii are scriptable

Pyhdiff Display the differences between two HDF4 files
Author(s) : Nicolas PASCAL (HYGEOS/ICARE-CGTD)
Written in : python, HDF4

This tool compares the structure of two HDF4 files (and netcdf3 if the HDF4 library is compiled with the netcdf support enabled). Its shows difference of datasets and metadata (global and dataset ones). For different datasets, it displays some statistics on it (mean difference, standard deviation and min/max values)

ReadRawFile Useful Python module for reading binary files in a generic way
Author(s) : Bruno SIX (ICARE - CGTD)
Written in : Python, Numpy

This tool is a generic reading Python module for all binary files consisting in some headers followed by records with the same pattern.
Headers and record patterns are described in text files. Datasets are returned as Numpy arrays.

Remap A reprojection tool of geolocated data between various grids
Author(s) : Fabrice DUCOS ( ICARE - LOA, Univ. de Lille )
Written in : C,C++

Remap is a tool designed to reproject geolocated data (i.e. data with at least known latitudes, longitudes, and expectedly, time).
The tool can read various products and reprojects one (or several ones) into another, using a nearest pixel search.
This tool is SID (still in development) but may be used as is for the supported products (each version documents its supported products).
At this time, CALIPSO IIR, SEVIRI, MODIS and PARASOL are supported.

Xrit2raw A tool to convert XRIT/SEVIRI data into a simple, headerless, raw binary file (along with libxrit, the library xrit2raw is based upon)
Author(s) : Fabrice DUCOS ( ICARE - LOA - Univ. of Lille )
Written in : C

xrit2raw is a simple tool designed above the libxrit library, in order to convert the XRIT format into a raw format, for people who don't want to bother themselves with programming. The output will be a simple, headerless binary file, with 3712x3712 values of radiances for the low resolution channels, or with 11136x11136 values for the high resolution channel HRV (in native 16-bit integer, or scaled simple or double precision floating point values, depending on the options set by the user).

Source codes are distributed as compressed archives (.tar.Z or .tar.gz). To uncompress them, you can use :

  • "uncompress" : .Z files
  • "gunzip" : .gz files
  • "tar xzf" : tar.gz and .tgz files
  • "tar xjf" : tar.bz2 files

For IDL tools, both the source code (.pro) and the compiled version (.sav) are provided. The use of source codes may require a proper IDL licence, while the compiled version can be used through the IDL virtual machine that can be downloaded from the IDL website : www.ittvis.com
