摘要：
The Salar de Uyuni is a large, flat and radiometrically homogeneous area. Its extent is several tenths the SMOS footprint and its emissivity is high and rather homogeneous except when flooded (about 3 months per year). It is located in a rather un-inhabitated area with no RFI. Therefore it provides a perfect calibration site for SMOS brightness temperature and the dielectric constant product validation. In this paper several calibration/validation issues were assessed: SMOS and AMSR-E brightness temperature cross-validation over the site, the influence of Full/Dual polarisation mode on SMOS angular signature and L2 dielectric constant product validation.
