DATA TOOLS
Software available for reading and analysis of data files from GES DISC and related data centers
This page describes available tools that can be used with data you retrieve from us or other data centers. NASA is not endorsing any of the commercial products, but providing this information strictly as a service to our users.
Currently Available Data Tools
HDF, HDF-EOS, and other EOSDIS Science Data Processing Toolkit material
|
HDF-EOS and SDP Toolkit
This is the home for all releases of HDF-EOS, tools like EOSView, HEG, and the SDP Toolkit libraries used in the EOS data processing centers. HDF-EOS User Manuals can be downloaded from that site. You can use the downloading instructions below* and then change ftp directory straight to what you need.
HDF
The home of the HDF group at the National Center for Supercomputing Applications (NCSA). Find the new HDF5, and many new precompiled command-line utilities.
|
HDFView is a visual tool for browsing and editing NCSA HDF4 and HDF5 files. Using HDFView, you can:
- View a file hierarchy in a tree structure
- Create new file, add or delete groups and datasets
- View and modify the content of a dataset
- Add, delete and modify attributes
- Replace I/O and GUI components such as table view, image view and metadata view

HDFLook is a multifunctional GES DISC data processing and visualization tool for MODIS (Radiometric and Geolocation, Atmosphere, Ocean and Land data) and AIRS L1B data. HDFLook is a result of joint collaboration between LOA USTL, France, and NASA GES DISC, and is based on the very popular MSPHINX tool philosophy. Created as a flexible modular tool, it is easy to update and add new features, and is free.

The GES DISC provides read software for accessing Aura and TOMS data files stored in the EOS Hierarchical Data Format (HDF-EOS5).
- The software 'read_h5' is written in the C language. You will need the HDF5 libraries when you compile the source code. The program allows users to select a parameter, latitude range, and dump the data to screen, ASCII file.
- The software 'atmos_h5' is an IDL based code. This program not only creates the parameter subsets (with option of converting data to geophysical parameters) and writes in ASCII or binary format, it also displays quicklook image on the screen and creates jpeg files.
- The read software for accessing TOMS level 3 daily gridded products (ASCII Format) are also available from DAAC. Please see this table for additional software which can be used to read Aura and TOMS data.
Software for reading TRMM and TRMM version 2 data files.
Also available here.
The Precipitation Processing System/TRMM Science Data and Information System provides the PPS/TSDIS Science Algorithm Toolkit, the Orbit Viewer THOR, and the VIRS L1B Radiance Converter.
This UARS read software programs read and dump the contents of all UARS level 3A data files (3AL, 3AT, 3LP, 3TP, 3AS/3BS, and UARS Correlative). The input file may be either the actual data file (PROD extension) or the metadata file (META extension). Output can be redirected to an ASCII file. Subsetting by latitude and vertical height can also be done. These software programs are no longer extensively maintained.

The listed tools are available to help handle and manipulate AIRS data files. The AIRS Data Support Team at GES DAAC is researching, testing and enhancing various software packages to designed to handle the HDF-EOS data format (the AIRS standard format). Inclusion of an externally developed software tool in the list below does not represent an endorsement of that tool by the Goddard Earth Sciences DISC.
