Regional evapotranspiration can be estimated with the equilibrium surface temperature and surface reflectance, both of which can be measured with scanning radiometers from airplanes or satellites. In case of vegetation covered soils information about the availability of soil moisture in the root zone can be obtained with the vegetation itself. For bare soil conditions the surface temperature variation in space and time supplies information about evaporation losses and apparent surface thermal admittance. In this paper the applicability of remotely sensed thermal images for vegetation covered and bare soil conditions is demonstrated by presenting some results of investigations in the Netherlands and Libya. In humid areas like the Netherlands in the near future the application of remote sensing will be mainly based on scanning techniques from airplanes. Satellite systems are of great importance in studying the water management in arid areas. |
