摘要: Abstract Arid and semiarid rangelands comprise a significant portion of the earth's land surface. Yet little is known about effects temporal spatial changes in surface soil moisture on hydrologic cycle, energy balance, feedbacks to atmosphere via thermal forcing over such environments. Understanding this interrelationship crucial for evaluating role cycle surface-atmosphere interactions. This study focuses utility remote sensing provide measurements moisture, albedo, vegetation biomass, temperature at different scales. Remote-sensing may only practical means estimating some more important factors controlling processes large areas. Consequently, use remotely sensed information biophysical geophysical models greatly enhances their ability compute fluxes catchment regional scales routine basis. However, model cal...
