摘要：
A map of instantaneous latent heat flux for a shrubsteppe site in south-central Washington was produced using Landsat Thematic Mapper data and simple ground based measurements. Latent heat nux ranged from <50 W m(-2) in rocky areas with little green vegetation to 100 W m(-2) at high elevations with cool temperatures to 160 W m(-2) in areas of high temperature and leaf area index. Quantitative remote sensing allowed us to predict absolute values of latent heat flux rather than relative values. This work supports efforts to produce a more mechanistic model for general use.
