Interannual variations of radiometric time profile and crop yield: coupling of functional model and short wavelength remote sensing observations

摘要

Temporal profiles of satellite radiometric signals were simulated for an agricultural area, at field (SPOT HRV) and regional (NOAA AVHRR) scales, using a vegetation process model (AFRCWHEAT2) and a radiative transfer model (SAIL). Furthermore, the authors show that assimilation of real satellite observations in a crop model leads to improved simulation of vegetation functioning.
