Launched in October 2006 (Metop-A) and September 2012 (Metop-B), they are the first European polar-orbiting satellites dedicated to operational meteorology. The Metop satellites carry onboard a set of state-of-the-art sounding and imaging instruments that offer improved remote sensing capabilities to both meteorologists and climatologists. The Metop series is part of the Initial Joint Polar-Orbiting Operational Satellite System (IJPS) constellation, along with the NOAA-18 and NOAA-19 satellites. The last satellite in the Metop series, Metop-C, was launched in November 2018 and it is expected to be fully operational in summer 2019.
