Abstract :
Precipitation sensitivity calculations suggest that a geosynchronous microwave (GEM) sounder/imager using millimeter- and submillimeter-wave channels at 50-57, 118, 183, 340, 380, and 424 GHz with a 2-3 meter diameter real aperture antenna will provide time-resolved radiance data valuable for tracking convective precipitation events using a numerical weather prediction (NWP) model. Presented are scattering-based Jacobian simulations of a landfalling hurricane that illustrate the capabilities of GEM for precipitation measurement and NWP-based radiance assimilation.
