Estimation of the Outgoing Longwave Flux from NOAA AVHRR Satellite Observations

摘要

Operational satellites provide global data from multispectral narrowbandradiometric scanners such as the Advanced Very High Resolution Radiometer (AVHRR) found on the polar-orbiting NOAA series of satellites. For many years, the narrowband channels have been utilized to estimate the components of the earth's radiation budget (Gruber, et al., 1983), although more accurate broadband instruments specially designed to measure them have been available (Jacobowitz, et al., 1984). Unfortunately, these instruments have been very intermittent in their coverage, with large gaps in time occurring between the failure of an instrument and the launch of its successor. Since ANHRR instruments have been present on every NOAA satellite since 1979 (refer to publication by NOAA, 1988), continuous coverage has been possible, although the radiation budget components are obtained with reduced accuracy.
