ICARE Data and Services Center and other collaborators tools

Anapol, is an IDL graphic interface for POLDER and PARASOL data visualization and analysis.
The functionalities of the program are:
Selection of the region of interest, Visualization of parameters, pixels extraction, composites creation, histograms plots, etc

This tool processes the average of multiple products and computes some additional statistics like the standard deviation, maximum and minimum per pixel. The input files and the output files are in HDF format.

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.

This page contains the code of a tool for giving informations on correlations between two variables or two images.

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.

A set of routines to compute latitudes, longitudes, azimutal and zenithal angles from rows and columns in the satellite grid (and the reverse)

This tool compress the datasets of a source HDF4 file using a gzip algorithm to a destination one. It also duplicates the SDS and file attributes.

This package contains some tools for manipulating HDF4 files :
- hdf2raw : write a HDF4 SDS to a binary file
- raw2hdf : write a 2D binary data to a HDF4 file
- ncf2hdf : convert a NETCDF file to an HDF one

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.

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.

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

Tool for comparing visually the POLDER2 and the MODIS coincident data

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

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)

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 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.

Tool for visualising several CALIOP data products through a graphic interface. Allows geographical selection, thresholding, export to images...

Tool for visualising several GLAS ( Geoscience Laser Altimeter System ) data products through a graphic interface. Allows geographical selection, thresholding, export to images...

A tool to provide coincidences between aeronet measurements and satellite aerosol products.

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).
