Paper Abstract

The Navy Indian Ocean METOC Imaging (IOMI) mission for the Geostationary Imaging Fourier Transform Spectrometer (GIFTS) will begin in early 2006 for a period of five years. The IOMI-GIFTS will measure Earth's outgoing infrared radiation with spatial (~4 km), temporal (~half hour), and spectral (~0.625 cm-1) resolutions and spectral coverages from longwave (LW, 685 - 1150 cm-1) for temperature profiles and short midwave (SMW, 1650 - 2250 cm-1) for moisture profiles. Retrieval of boundary layer moisture from IOMI-GIFTS with high vertical resolution and accuracy, is a special interest of the Navy, can provide water vapor wind information over the ocean. The characteristics of boundary layer moisture retrievals from IOMI-GIFTS are demonstrated. Both theoretical analysis and a simulation study with a GIFTS forward model developed at UW-Madison show that the contrast between surface air temperature and surface skin temperature has significant impact on the accuracy of boundary layer moisture retrievals. A large contrast (> 5 K) will result in noticeable boundary layer moisture improvement over that with less contrast.
