Abstract

Tropospheric wind is a top priority NPOESS EDR that can be retrieved by tracking high spatial resolution altitude-resolved water vapor sounding features in imagery provided by a humidity imaging sounder. A Wedge-filter Imaging Sounder (WIS) can provide the required humidity imagery and has already been studied for application in geostationary orbit by Puschell, Huang and Woolf. The Wedge-filter Imaging Sounder for Humidity (WISH) incorporates the same technology and is suitable for flight on the NPOESS C2 or C3 spacecraft. WISH would take advantage of payload capacity available for P3I demonstrations in NPOESS and would serve as a risk reduction and technology demonstration for future NOAA environmental satellite missions. In this paper, we present our analysis of a preliminary WISH sensor concept design, specification and expected radiometric sensitivity. The practicality of WISH for current NPOESS spacecraft configurations will also be discussed. The performance of WISH toward achieving NPOESS P3I's tropospheric wind objective will be discussed in a companion paper by Huang et al. in SPIE conference 5655.
