Abstract

The Geosynchronous Imaging Fourier Transform Spectrometer (GIFTS) is the first hyper-spectral remote sounding system to be orbited aboard a geosynchronous satellite. The GIFTS is designed to obtain revolutionary observations of the four dimensional atmospheric temperature, moisture, and wind structure as well as the distribution of the atmospheric trace gases, CO and O<sub>3</sub>. Although GIFTS will not be orbited until 2005, a glimpse at its measurement capabilities has been obtained by analyzing data from a series of aircraft flights of the National Polar-orbiting Operational Environmental Satellite System (NPOESS) Airborne Sounder Test-bed- Interferometer (NAST-I). In this paper we review the GIFTS experiment and empirically assess measurement expectations based on meteorological profiles retrieved from the aircraft data.
