Two-layer Model for Monitoring Drought Using Remote Sensing
农田蒸散双层模型及其在干旱遥感监测中的应用

In this paper a tow-layer model for evaportranspiration is estiblished in partial vegetation canopy. The vegetation canopy has two layers, the first one extends. from a refrence height in the atmosphere to the virtual sink for momentum and the second one from the virtual sink to the soil surface. NOAA-AVHRR data and the two-layer model are applied to estimate evaportranspiration and drought of wheat grown in Huang Huai Hai plain.
