Processing and Application of Digital AVHRR (Advanced Very High Resolution Radiometer) Imagery for Land and Sea Surfaces

摘要

A software-package for reading NOAA AVHRR-data tapes, calibration of the raw data, cloud detection, calculation of Earth surface parameters, and geometric correction of images was adjusted to perform automatically. Applications of AVHRR data, including observation (and perhaps warning) of damage in the agriculture caused by drought, night-frost etc; monitoring of meteorology related, troublesome situations for traffic like fog, snow and frost; locating fronts in the sea surface temperature, which might be areas with increased occurrence of certain fish-species, and input of sea surface temperature data for meteorological, oceanographic, and climate models were assessed. Results show that the AVHRR is a powerful tool for the monitoring of processes in the Earth-atmosphere system, especially for the monitoring of sea (lake) surface parameters. The coarse spatial resolution renders Advanced Very High Resolution Radiometer (AVHRR) data less suitable for land surfaces.
