                         using active microwave remote sensing. With the existence of 
                         airborne systems, it is now possible to estimate this variable on 
                         a regional scale. Data from a helicopter-borne scatterometer show 
                         that the surface water content reductions during a 9-day period 
                         are quite different from one field to another. A simple model 
                         describing the water budget of the soil surface layer due to 
                         evaporation and drainage is applied. From this model, a 
                         pseudodiffusivity can be calculated for each field using only the 
                         remotely sensed data. This new parameter gives a quantitative 
                         estimate of the observed drying heterogeneities.",
