Introduction
The Terra-aqua eXperiment 2002 (TX-2002) is being conducted from the former Kelly AFB in San Antonio, Texas from November 20 to December 13, 2002 to assess MODerate resolution Imaging Spectroradiometer (MODIS) and Atmospheric Infrared Sounder (AIRS) L1B and science products from the Terra and Aqua satellites.

Instrument Summary
The Scanning High-resolution Interferometer Sounder (S-HIS) is a scanning interferometer which measures emitted thermal radiation at high spectral resolution between 3.3 and 18 microns (specifications).  The measured emitted radiance is used to obtain temperature and water vapor profiles of the Earth's atmosphere.  S-HIS produces sounding data with 2 kilometer resolution (at nadir) across a 40 kilometer ground swath from a nominal altitude of 20 kilometers onboard a NASA ER-2 aircraft or 20 kilometer ground swath from a nominal altitude of 10 kilometers aboard the NASA DC-8 aircraft.

Related Links Software
S-HIS data are stored in network common data format (netCDF).  Programs for reading S-HIS data in this format are available in Fortran, IDL, Matlab source code.  To visualize S-HIS data, a Matlab browser is available for basic image viewing.
