Precipitation Retrieval From Spaceborne Microwave Radiometers and Combined Sensors

Abstract

Applications of space-based microwave radiometry to precipitation retrieval is addressed, focusing on model-based inversion techniques and optimal combination with other satellite sensors. Statistical integration of microwave radiometers with space-borne radars and thermal infrared radiometers is sketched. Examples of measurements and products are shown to emphasize the physical background of combined techniques. The concept of the newly approved NASA/NASDA Global Precipitation Mission (GPM), considered to be the Tropical Rainfall Measuring Mission follow-on international space program on precipitation remote sensing, is finally illustrated together with concluding remarks on current status of precipitation retrieval.
