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.
You can browse the quicklooks available for selected S-HIS field campaigns, sorted by year.

Below is the link to the online archive of S-HIS data. Additional data from all field campaigns is being added.
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.
Algorithms using S-HIS data are being developed to retrieve remotely sensed temperature and water vapor profiles, sea surface skin temperature, land surface temperature and emissivity, cloud top temperature and emissivity, and trace gas total column amounts.
The S-HIS instrument was developed jointly with Bomem, Inc. Support for S-HIS development has been provided by the Department of Energy, NASA, and the Integrated Project Office (IPO).
