Abstract

The size, structure, spatial homogeneity and temporal thermal stability of some regions in Antarctica such as Dome-C, make them good candidates for the external calibration or validation of upcoming spaceborne L-band radiometers such as SMOS. As experimental observations are lacking at this frequency, an electromagnetic modelling approach is applied to qualitatively assess the potential of these areas.
