The Earth Observing System (EOS) is the major element in the National Aeronautic and Space Administration's Mission to Planet Earth. It will be a 15-year-long mission, employing space-based instrumentation and in situ measurements to provide a long-term, contiguous, calibrated, and validated data set that addresses geophysical and biochemical phenomena occurring in the Earth system. The EOS suite of satellites includes sun-synchronous, polar-orbiting spacecraft with morning or afternoon equator-crossing times. The EOS-AM series, the first of which is slated for launch in June 1998, will address geophysical and biogeochemical processes occurring at or near the Earth's surface; the EOS-PM platforms will address atmospheric phenomena, including the interaction between clouds and radiation. Synergy and complementarity within and between these and other platforms will play a major role in acquiring high-quality data. We discuss the following instruments: Moderate Resolution Imaging Spectroradiometer (MODIS), Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Multifrequency Imaging Microwave Radiometer (MIMR), Multiangle Imaging Spectroradiometer (MISR), and Atmospheric Infrared Sounder/Advanced Microwave Sounding Unit/Microwave Humidity Sounder) (AIRS/AMSU/MHS). Instrument heritage, design, capabilities, and realization are discussed in terms of satisfying scientific requirements. We also discuss the synergy resulting from cross-calibration of the instruments and validation of their resulting data products.
