AB: The University of Wisconsin Scanning High-resolution Interferometer Sounder (S-HIS) provides the high spectral resolution infrared observations on the high altitude NASA ER-2 aircraft to complement the MODIS Airborne Simulator (MAS) and the NASA Cloud Physics Lidar (CPL) on the same aircraft platform. These instruments provided high spatial resolution aircraft measurements during the NASA TC4 experiment in July-Agust 2007 in a manner similar to the lower spatial resolution observations from the AIRS, MODIS, and CALIPSO sensors on the NASA A-train. The S-HIS measures the upwelling infrared spectral radiance between 3.3 and 18 microns at 0.5 cm-1 (unapodized) spectral resolution in a cross-track swath of 14 fields of view of approximately 2 km diameter. The S-HIS is an airborne version of the advanced sounder AIRS found on the NASA Aqua satellite, the IASI sensor on the METOP-A satellite, and the CrIS sensor on the NPP/NPOESS platforms. During the TC-4 campaign based out of San Jose, Costa Rica, the S-HIS compiled a nearly perfect record of measurements for each ER-2 flight. Highlights of these missions will be presented in this paper, including measurement of the elevated dry layer associated with a Saharan Air Layer (SAL) sampled on 19 July 2007 in the Caribbean sea, measurement of upper level water vapor over the Galapagos Islands coincident with in situ validation, and retrieved levels of carbon monoxide associated with biomass burning. The retrieval uses Bayesian estimation based upon a maximum a posteriori (MAP) method which combines information contained in the spectral radiances with a priori information provided by climatological measurements for the TC4 domain. This paper includes a description of the S-HIS observations, the inversion method, prelimianry results, and comparison to model and validation data.
