NASA's Geostationary Earth Observatory and its optical instruments

Abstract

The baseline mission concept of the Geostationary Earth Observatory (GEO) calls for five Earth Science Geostationary Platforms (three by NASA, one by Europe, and one by Japan) to be deployed around the earth. This paper discusses the science goals of the GEO, the GEO platform concept, the instrument complement proposed for the GEO mission, and the various optical technology issues involved in the instrument operation. The instruments proposed include the Geostationary Microwave Precipitation Radiometer, the Geostationary Atmospheric Profiler, the Geostationary Earth Processes Spectrometer, the Advanced Lightning Mapper, and the High Resolution Earth Processses Imager. The instruments' design diagrams are included.
