摘要: Measurements of the microwave brightness temperature (TB) with Pushbroom Microwave Radiometer (PBMR) over Walnut Gulch Experimental Watershed were made on selected days during MONSOON 90 field campaign. The PBMR is an L-band instrument (21-cm wavelength) that can provide estimates nearsurface soil moisture a variety ofsurfaces. Aircraft observations in visible and near-infrared wavelengths collected also used to compute vegetation index. Continuous micromctcorological measurements daily samples obtained at eight locations experimental period. Two sites instrumented time domain refleciometry probes monitor profile. fraction available energy for cvapotranspiraii was computed by taking ratio latent heat flux
