Using remotely sensed data to estimate surface albedo and absorbed photosynthetic active radiation

Field spectrometer and pyranometer data from the First ISLSCP Field Experiment (FIFE) of the Konza tall grass prairie were used to study algorithms for estimating surface albedo and absorbed photosynthetic active radiation (APAR). The purpose is towards developing an approach to use repetitive and synoptic satellite data such as from the NOAA Advanced Very High Resolution Radiometer (AVHRR) to derive biophysical parameters at the land surface. Several algorithms and corrections are studied-to reduce the error from using remotely sensed data to estimate surface albedo and APAR
