Abstract

The ground-based radiometer-scatterometer system of the University of Bern, RASAM, measures brightness temperatures and backscattering coefficients at frequencies between 2 and 12 GHz. Between 1984 and 1992 many campaigns were carried out on agricultural fields. Data from more than 70 bare agricultural soils have now been organized in a bare soil signature catalogue. In addition to the microwave data, detailed ground-truth information was collected including highly accurate surface roughness profiles. Information on the data base is given, together with short descriptions of the instruments and measurement procedures
