SMOS Microwave Imaging Radiometer using Aperture Synthesis (MIRAS) consists of a central structure and three arms that carry 69 antenna receivers. The instrument employs a new measuring technique in space by operating at frequencies around 1.4 GHz (L-band) to capture images of microwave radiation emitted from Earth.
From an altitude of 758 km and data obtained from a swath width of about 1000 km, SMOS achieves global coverage every three days.

Following cooperation between ESA and the National Spectrum Authority, SMOS data over Spain, shown in this image from July 2010, are now far less contaminated by radio-frequency interference.
