EUMETSAT Contribution to Global Ozone Monitoring - current programmes

• EUMETSAT is contributing to climate monitoring and in particular to global ozone monitoring through its current and future programmes.

• GOME-2 on the EPS/Metop series of satellites, which are providing global data in the 2006 to 2020 time-frame, continues the long series of measurements from GOME-1/ERS-2 and SCIAMACHY/ENVISAT, and provides global total column ozone and ozone profile information.

• In addition, key parameters relevant to ozone chemistry are provided. EUMETSAT’s Ozone Monitoring and Atmospheric Chemistry Satellite Application Facility, hosted by FMI, provides this information.

• Furthermore, EUMETSAT provides ozone information from IASI (Infrared Atmospheric Sounding Interferometer), the hyper-spectral infrared sounding mission on Metop, within the Level 2 global sounding product. Information on ozone, both in 3D and total column amount, complement the information provided by GOME-2.

EUMETSAT Contribution to Global Ozone Monitoring - future programmes

• A hyperspectral Infra-Red Sounding mission is envisaged to be flown onboard the geostationary satellites of the Meteosat Third Generation. The MTG-IRS will provide ozone monitoring on an hourly basis over the hemisphere as seen from the geostationary position.

• Further on, the GMES Sentinel-4 mission is planned to be embarked on the same MTG sounding satellite providing additional ozone monitoring capabilities in the UV/visible at a temporal resolution of one hour over a region of 4.5° N/S - 9°E/W centred on Europe.

• MTG, currently in its Preparatory Programme, and about to start Phase B activities at industry level, is expected to deliver measurements within the 2015 – 2030 timeframe.

• In the frame of the EPS follow-on programme (post-EPS) requirements for ozone and atmospheric chemistry monitoring are expressed, and are currently expected to be realised via the EC GMES initiative and in particular in the Sentinel 5 mission, which is planned to be embarked on post-EPS. This will provide continuity in the global ozone monitoring from polar sun-synchronous orbit.
