Earth Science in NASA Strategic Plan 4.2.2 Weather: Enable improved predictive capability for weather & extreme weather events.  Current GEO imager/sounder instruments operate at infrared wavelengths. Instruments operating at these wavelengths cannot “see” below the clouds, which are generally present whenever interesting meteorology is taking place. In order to take full advantage of GEO observations, it is necessary that the infrared instrument suite is complemented with microwave cloud-penetrating instrumentation. AIRS and AMSU have reached the maximum vertical resolution attainable with passive sounding. Improvements in the vertical resolution will be necessary to satisfy the requirements of the numerical weather prediction models of the next decade. Further improvements in vertical resolution may require the development of active (lidar and/or radar) sounding techniques.
