Operational satellite support to scientific programs

Abstract : This report examines the role of operational environmental satellites in science programs undertaken to study the Earth system. It centers on the satellite systems operated by the National Oceanic and Atmospheric Administration (NOAA). Other satellite systems are referenced as appropriate. NOAA's operational satellites are serving the research community extensively. Research programs such as climate studies, ocean dynamics investigations, and global vegetation surveys benefit from the special characteristics of operational satellites. Among these characteristics are routine global coverage in many spectral intervals; reliability, resulting from a commitment to continue the service; speed in data access because of real-time applications; repeatability of measurements because of matched, calibrated instruments; and data handling methods that provide output products in conventional, usable formats and with traceable histories.
