The Meteosat Third Generation (MTG) series of future European geostationary meteorological missions consists of two satellites: the imaging satellites (MTG-I) and the sounding satellites (MTG-S). The Infrared Sounder (IRS) is one of the two instruments hosted on board the MTG-S satellites.
The MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) International Arctic Drift Expedition) expedition (http://www.mosaic-expedition.org) successfully delivered a benchmark dataset involving in situ and satellite measurements of active (Ka-, Ku-, X-, C- and L-band) and passive (P, L, C, X, K, and Ka-band) microwave data and fiducial reference measurements of snow and sea ice physical properties over a complete annual cycle in 2019-2020.
