A global map of aerosol optical depth using the Polar Multi-Sensor Aerosol product for 3 March 2013
EUMETSAT indirectly contributed to the 6 th assessment report as a
key provider of input data for global numerical weather prediction
model-based reanalyses. Through its support to the Copernicus
Climate Change Service, operated by the ECMWF, EUMETSAT
delivered a significant number of data records to the fifth generation
of the ECMWF’s atmospheric reanalysis, ERA5. This reanalysis is
widely used in the IPCC 6 th assessment report.
MORE TO COME
Major evolutions in 2021 were the finalisation of a best calibrated
version of the Metop GOME-2 instrument data that enabled the
production of an aerosol data record utilising the latest algorithm
for the Polar Multi-Sensor Aerosol Product. Covering the lifespan
of Metop-A, and Metop-B until the end of 2019, it will be released
in 2022. The data record is useful to analyse temporal changes
in desert dust plumes, biomass burnings, anthropogenic
pollution, and volcanic emissions worldwide. In addition, a cloud
property data record has been derived from the Meteosat SEVIRI
instrument’s observations.
EUMETSAT provides examples of how its data are used in climate
applications. In 2021, the climate use cases centred around themes
of interest to the IPCC, such as long-term changes in sea ice
area, the effect of increased melt from the Greenland glacier on
temperatures in the North Atlantic, and using atmospheric wind
data to better understand changes in the North Atlantic Oscillation.
All climate use cases can be found on EUMETSAT's website.
