The data displayed in the following table were collected at the INRA research centre near Avignon (43°55'N, 4°53'E, south of France) in 1993. Emissivity values were estimated from the measurements made by the PORTOS radiometer. The atmospheric and sky contributions were removed from the brightness temperature measured by PORTOS by an algorithm described in Calvet et al. (1995). Atmospheric and sky contributions were estimated using the outputs of the Meteo France 15 levels weather forecast model PERIDOT and the cloud observations made at the experimental site along with the radiometric acquisitions. The surface effective temperature was estimated by the skin temperature measured by a thermal infrared radiometer. The expected error in microwave emissivities is ±0.015.
