The Multispectral Imaging Radiometer (MIR) on METEOSAT-2, -3, -4, and -5 collects data over the Earth in three spectral regions, one in the visible and two in the infrared. The satellite scans the Earth from east to west and, if the water vapor channel (6.7 um) is turned off, is capable of producing a resolution of 2.5 km.
