EUMETSAT Contribution to Global Ozone Monitoring Rosemary Munro Dieter Klaes

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. EUMETSATs 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.
