Results of radiometric measurements over bare soil obtained with a horizontally polarized microwave radiometer at 19#xB7;1#x2009; GHz frequency are presented. Radiometer measurements were made with incidence angles varying from 10 to 50#xB0;. Ground-truth acquisition of soil moisture in the 0#x2013;1#x2009; cm layer and of soil temperature near the surface was made concurrently with radiometer measurements. The measured brightness temperatures over a bare field are higher than those calculated from an emmissivity model.
