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 scope of the IRS mission is to provide the user community with information on time evolution of humidity and temperature distribution, as function of latitude, longitude and altitude. In this context, EUMETSAT has established the IRS Mission Advisory group (IRS-MAG) with the mandate of providing independent advice on the scientific concepts, Cal/Val approaches, and data usability of the IRS mission.
