Definition

  • The Scanning High-resolution Interferometer Sounder (S-HIS) is a cross-track scanning interferometer sounder which measures emitted thermal radiation at high spectral resolution between 3.3 and 18 microns. The measured spectrally resolved radiance is used for a variety of applications, including retrieval of temperature and water vapor profiles of the Earth's atmosphere, determination of surface emissivity and temperature, and validation of radiative transfer models and satellite measurements. The S-HIS produces sounding data with 2 kilometer spatial resolution (at nadir) across a 40 kilometer ground swath from an altitude of 20 kilometers (0.100 mrad FOV). The S-HIS instrument flies on a number of airborne platforms including the NASA ER-2, DC-8, Proteus, WB-57, and Global Hawk. On the Proteus and WB-57 aircraft, a zenith view is available, providing a means for calibration verification and studies of upper level water vapor. The S-HIS is an advanced version of the HIS NASA ER-2 instrument. The S-HIS was initially designed to fly on an unmanned aircraft vehicle (UAV) with limited payload capacity. This drove it to be small, lightweight, and modular, with low power consumption. It was developed between 1996 and 1998 at the University of Wisconsin (UW) Space Science and Engineering Center (SSEC) with the combined support of the US DOE, NASA, and the NPOESS Integrated Program Office. Its design and calibration techniques have matured from experience with the HIS and with the ground based Atmospheric Emitted Radiance Interferometer (AERI) instruments developed for the DOE Atmospheric Radiation Measurement (ARM) program. The nadir-only spatial sampling of the original HIS has been replaced by programmable cross-track coverage with similar sized footprints. The S-HIS is also smaller, more robust, and easier to operate. Since 1998, the S-HIS has flown in several field campaigns and has proven to be extremely dependable and effective. The S-HIS instrument is maintained and operated by the Space Science and Engineering Center at the University of Wisconsin-Madison in Madison, WI. The principal scientific investigator for the S-HIS is Dr. Joe K Taylor (en)
