SMUDP Level 2 data obtained by SMOS at 05:05 on 04 January 2011.

The ESA's Soil Moisture and Ocean Salinity satellite is a part of the Living Planet program and provides observations in the low frequency range of microwaves (L-band, 1.4 GHz) using an interferometric radiometer. The moisture content in a soil decreases its emissivity and thereby affects the microwave radiation emitted from the Earth's surface. The SMOS level 2 data provide both the soil moisture retrieval and the brightness temperature (Tb) measurements. The figure represents a full orbit acquisition of Tb at horizontal polarization, the region of interest is the Sahara desert, considering a multi-temporal data set small variation of soil moisture is expected.
