Data reading software
Reading software are provided with Aviso data for the various data formats available. Note that since we can't provide those for all existing languages and platforms, those programs may not work for your precise configuration.
Basic Radar Altimetry Toolbox
The Basic Radar Altimetry Toolbox is a collection of tools and tutorial documents designed to facilitate the use of radar altimetry data. It is able to read most distributed radar altimetry data from all the satellites, to do some processing, data editing and statistic over them, and to visualise the results. The Basic Radar Altimetry Toolbox is able to read ERS-1 and 2, Topex/Poseidon, Geosat Follow-on, Jason-1, Envisat, and the future Jason-2 and Cryosat missions altimetry data from official data centres (Esa, Nasa/JPL, Cnes/Aviso, Noaa), and this for different processing levels, from level 1B (Sensor Geophysical Data Record) to level 3/4 (gridded merged data).
NetCDF data
Reading software are available at ftp://ftp.cls.fr/pub/oceano/AVISO/software/
For NetCDF data (both gridded and along-track), two different sets of programs are available:
- Sources programs:
PublicReadDelivery.tar.gz contains read/write libraries plus sample ascii dump programs in C/Fortran. - Precompiled packages
PublicReadBinaries.Linux.tar.gz, PublicReadBinaries.MSWindows.zip, PublicReadBinaries.SunOS.tar.gz contain precompiled binary files corresponding to the above mentionned libraries.
Readme explaining the content of each tar files are provided inside.
Note that NetCDF data can be browsed and used through other software, like:
- ncBrowse
- NetCDF Operator (NCO)
- The Live Accesss Server is also a visualization tool that can be used to preview data (Ssalto/Duacs gridded NRT and DT data)
- Through the Opendap
GDR data
Dedicated reading software for Jason-1 (I)GDR and OSDR are available at ftp://avisoftp.cnes.fr/AVISO/pub/jason-1/documentation/software/
They are provided for the following languages : C, Fortran, IDL, Java, PVWave, VBasic. A Readme is available in the sub-directories containing the programs.
For Topex/Poseidon MGDR data, reading programs in Fortran (Unix and Vax) are delivered with the CD Roms.
