The Joint Airborne IASI Validation Experiment was an international cal/val campaign in support of the NPOESS and MetOp series of operational satellites. Although all measurements on the MetOp-A and A-train satellites were of interest, the focus of JAIVEx was on the validation of radiance observations and meteorological products from the Infrared Atmospheric Sounding Interferometer, IASI. IASI, on MetOp-A launched 19 October, 2006, was the first of the advanced ultra- spectral resolution temperature, humidity, and trace gas sounding instruments flown on the Joint Polar System (JPS) of NPOESS and MetOp operational satellites for the purpose of improved weather, climate, and air quality observation and forecasting. IASI measured radiation emission from the surface and atmosphere in the 645 – 2760 cm-1 (i.e., 3.6-15.5 ìm) spectral band with high spectral resolution (i.e., 8461 spectral channels with a spacing of 0.25 cm-1). As MetOp- A orbited overhead, IASI scanned the Earth between ± 49° providing a swath of data across the Earth of 2132 km. The scan swaths were made with a frequency to provide contiguous coverage across the Earth’s surface as the satellite orbited overhead. Seven consecutive orbits, each with a 101 minute period, provideed total Earth coverage every twelve hours. The aircraft employed were the NASA WB-57 and the FAAM BAe 146.The aircraft base location, dates of the experiment, satellite, airborne, and surface resources used for JAIVEx, as well as the participants and sponsors, are summarized below.
