EURO4M Newsletter, February 2013

The European Reanalysis and Observations for Monitoring project is a EU funded project that provides timely and
reliable information about the state and evolution of the European climate. It combines observations from satellites,
ground-based stations and results from comprehensive model-based regional reanalyses. By closely monitoring
European climate, climate variability and change can be better understood and predicted.

This February 2013 newsletter highlights some of the the achievements of the project thus far. More information on
the EURO4M project can be found on the project website.

Regional reanalysis

Preliminary results for the high resolution regional reanalysis datasets for Europe developed in EURO4M have become
available. The UK MetOffice demonstrates a new 4DVar-based reanalysis system for an initial 3-month period during
summer 2010. Complementary to this, the HIRLAM 3D-VAR re-analysis system is set up by SMHI and run first for 2009
and then for 1989-1992. It is for a large region covering Europe (EEA members) and most of the North Atlantic.

The maximum surface temperature on 7 July, 2010, during the Russian heatwave based on E-OBS (KNMI),
ERA Interim, and the 4D-Var based reanalyses (UK-MO).

More information on the high resolution re-analyses activities of the project can be found here.

Surface Radiation

Comparison with ground-based measurements shows that the EURO4M surface radiation products are of high quality.
Within the EURO4M project KNMI delivers data sets of surface solar incoming radiation retrieved from SEVIRI satellite
data. An improved algorithm is used, decomposing the radiation into its direct and diffuse component, by considering
the effect of aerosol variations and by using a better dataset of the surface albedo. The estimates of surface solar
incoming radiation are validated by comparison with ground-based measurements.

Data rescue

New data series from countries in North Africa have become available. In the first two years of the project a team
from the University Rovira i Virgili (URV), Spain, has digitized more than two thirds of the observations from sites
in Tunisia, Libya, Egypt, Syria, Lebanon and Cyprus (see map below). Data from any station located in the
neighborhood of each site have been used for constructing long-term, as-complete-as-possible (after merging) and
reliable (after quality-checking and homogenization) time series.
Several quality controls are run such as gross check errors, tolerance tests, internal coherency and temporal and
spatial consistency checks.

Climate Indicator Bulletin

The first EURO4M Climate Indicator Bulletin has been published. A Climate Indicator Bulletin (CIB) is a user-driven
climate information product which provides a simple, effective and timely knowledge abstraction from the large
amount of raw observation and reanalyses data available in EURO4M. The bulletins focus on user groups in sectors
such as disaster prevention, health, energy, water resources, ecosystems, forestry, agriculture, transport, tourism and
biodiversity at European, national and local levels.
The first bulletin gives an overview of European temperature based on a large number of measurements.
The observations are presented in their historical context with special attention to trends and overviews of
recent temperature.

Observed surface air temperature aggregated into European temperatures as described in Van der Schrier et al., 2012.
The figure shows the annual mean values in this E-OBS dataset for the land area between 35°N-75°N and 25°W-45°E,
as shown in the small insert on the right.

The full CIB on European Temperature can be found here.

Interaction with Users

For the second time EURO4M will organize a User Workshop. The workshop will focus on the latest EURO4M products
(including in-situ data, satellite-derived products and reanalysis data sets) and climate applications. This workshop will
take place on the 14th and 15th May, 2013 at the German Weather Service, Offenbach, Germany. For more information
please send an email to

On the EURO4M website two short Podcosts are published explaining the objectives, expected results and impact of the
project. They can also be accessed directly here ( PodCast1 and PodCast2).
