SMUDP Level 2 data obtained by SMOS at 11:16 on 01 July 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, in particular the lesson will focus on the central area of North America where multi-temporal data set is considered to show the seasonal changes of soil moisture over temperate climate areas.
