Europe’s first MetOp Second Generation, MetOp-SG-A1, weather satellite – which hosts the Copernicus Sentinel-5 mission –  has launched aboard an Ariane 6 rocket from Europe’s Spaceport in French Guiana. The rocket lifted off on 13 August at 02:37 CEST (12 August 21:37 Kourou time).

MetOp-SG-A1 is the first in a series of three successive pairs of satellites. The mission as a whole not only ensures the continued delivery of global observations from polar orbit for weather forecasting and climate analysis for more than 20 years, but also offers enhanced accuracy and resolution compared to the original MetOp mission – along with new measurement capabilities to expand its scientific reach.

This new weather satellite also carries the Copernicus Sentinel-5 mission to deliver daily global data on air pollutants and atmospheric trace gases as well as aerosols and ultraviolet radiation.
