The first geostationary sensors produced dramatic images of storms on short time scales, permitting their evolution to be monitored as never before. Prediction of weather now benefits from numerical weather prediction models, which require temperature and humidity inputs from soundings. Significant weather is often located in cloudy areas where infrared (IR) soundings are degraded or fail, and since numerical weather models are often hypersensitive to such baroclinic regions, microwave sounders can improve predictions by providing needed data. Both theoretical studies and data from polar weather satellites make clear the superiority of combined IR and microwave sounder systems relative to either system operating alone [ 11. To date, the size and weight of microwave sounders have limited their use to low earth orbit. The use of higher frequencies can provide reduced antenna size so that a useful microwave sounder using a -2-meter diameter aperture can be packaged on a geosynchronous satellite [2].
