Abstract

TELLUS' main goals were a) to ascertain whether remote sensing can contribute to the evaluation of evapotranspiration and moisture in agricultural soils, and to what extent; b) to evaluate the influence of physiographic characters of land on surface temperature distribution; c) to investigate anthropogenic heat release from space. A systematic approach was adopted for the development and testing of ET algorithms using remotely sensed radiative temperature and albedo. Evapotranspiration and soil moisture mapping was obtained as a result of the methodical Joint Flight Experiment applications on areas of homogeneous nature with regard to crops and soil moisture content in the upper soil layer was obtained from the thermal inertia. The investigation has confirmed also that the HCMM satellite was very pertinent to the evaluation of anthropogenic heat release on a regional scale and thermal pollution of large water bodies. Day-and subsequent night description of surface temperature distribution appeared to be essential to assessments of thermal daily variability of heat sources on the scene.
