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 (BRAT)

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).

Reading NetCDF data

For Jason-2 NetCDF, reading software are available on the aviso ftp: in the folder /geophysical-data-record/jason-2/documentation/software

Note that NetCDF data can be browsed and used through other software, like:

Marine Geospatial Ecology Tools

Marine Geospatial Ecology Tools (MGET) is an open source geoprocessing toolbox developed by Duke University Marine Geospatial Ecology Lab designed for coastal and marine researchers and GIS analysts who work with spatially-explicit ecological and oceanographic data. MGET includes over 150 tools (among which the Aviso downloading tool) useful for a variety of tasks, such as converting oceanographic data to ArcGIS formats. Currently under development are tools for identifying rings and eddy cores in sea surface height images, for analyzing connectivity networks, for estimating fishing effort when no effort data are available, for predicting hard bottom habitat from coarse grain bathymetry, and much more.
