摘要
Satellite data, principally from SPOT, were used to make regional forecasts of sugar beet production in England. Crop canopy cover f was estimated from vegetation index measurements and used to adjust parameters of an empirical-agrometeorological model of the f profile. Production forecasts within 0.1 t/ha were achieved for over half the regions. SAR data also gave promising results, with lower absolute precision but greater regularity of acquisition.
