TOOLS

Aura data products are mostly in the new HDF-EOS5 file format (level 2 and 3), however there are some products which are not (level 1 OMI is in the old HDF-EOS2.x, and level 1 MLS is in plain HDF5). You will need to choose the correct software to read a particular data product (see the descriptions of the data product levels below for more information).

In some cases, conversion tools exist to convert data from one format to another. One may convert older HDF-EOS2.x to the new HDF-EOS5 format. One may also convert files from old HDF4.x to the new HDF5 format, and vice versa. Note that HDF-EOS files are a collection of HDF objects. Thus HDF software will read HDF-EOS files, but you must choose the correct version, as HDF5 is not backward compatible with the old HDF4 format.

The table below lists some readers and visualization tools including **Giovanni**, an on-line visualization service.

Descriptions on other tools can be found at the HDF-EOS home page. For information about the HDF or HDF5 format, please see the HDF home page.

Readers and Visualization Tools for Aura Files in :
  • HDF4 & HDF-EOS2.x Formats (e.g. OMI Level 1B Products )
  • HDF5 and HDF-EOS5 Formats (e.g. OMI, MLS, and HIRDLS Level 2 Products)
