SHOWCASE EUROGRID
Is there a need for a European core service component for
high-resolution gridded climate data and products?
Thomas Klein & Christer Persson
The EUROGRID-vision
• EUROGRID – A European resource for gridded
climate data and products,
• Delivering tailored information and added value
to a variety of users from
• Environment, meteorology+climatology,
hydrology, oceanography, energy-sector,
agriculture, forestry, insurance-sector, …
Showcase EUROGRID:
A EUMETNET/ECSN optional programme
Basic objectives:
• demonstrate how shared gridded historical meteorological
and environmental data from European NMSs can be used
for products and services for the European society
• Investigate the needs for and prepare for an efficient use of
results from future high-resolution European re-analyses
(EURRA) – but the build-up of a mature system and the
accomplishment of a consistent European reanalysis is not
included!
• prepare for the realization of the full-scale EUROGRIDconcept as support to user requirements and in line with
relevant European and Global initiatives
EUROGRID
vs
Showcase EUROGRID
Solid, sustainable funding
Mini-budget, 2-year project, in-kind
contributions by the 16 participants
Consistent high-resolution dataset
for whole Europe
Scattered national initiatives,
diverse in methodology, indata,
variables, resolution in time and
space
Infrastructure facilitating easy
discovery, access and dynamic
processing of information
Demo-system, illustrating basic
ideas and potential of a mature
system
Integration and interoperability with
other service components
Use of open standards and
protocols
Tailored information, addressing
specific user requirements
Investigation of user requirements
=> User questionnaire
Showcase EUROGRID Services and Products
• Essential climate variables:
temperature and precipitation
• 2 European datasets
(ERAMESAN, ENSEMBLES)
• 8 high-resolution datasets for
specific countries
• Selected years (2002+2003)
• Examples for ”Derived” Products
• Atmospheric Chemistry/Air
quality/Deposition example
• Geospatial and temporal
aggregation products
Showcase EUROGRID Services:
Part 1: MapView (2D-raster files)
• Data visualization
• Open protocols [OGC/ISO
WMS]
• Visualization of distributed
data (hosted at the members’
sites) using a common portal
[frontend OpenLayers]
• Pre-processed products
hosted at central site
• Data dissemination
• Open protocols [OGC WCS]
• Client-based product
generation [e.g., user’s GIS]
Showcase EUROGRID Services
Part 2: DataView (Time series from SQL-database)
• Data visualization
• Extraction of data at grid
points from MySQL5database by mouse-click
• Plot of time-series
• XHTML-table
• Data dissemination
• XHTML-table
• Other formats (to be
implemented if desired)

GMES & reanalyses
• The GMES Atmosphere Service (GAS) currently
addresses
• air quality, atmospheric composition, the radiative
forcing of climate, UV and renewable energies
• What about information on the physical state of the
climate (ECV’s), allowing for
• the assessment of multi-decadal trends
• the assessment of frequency and intensity of extreme
weather-related events
• timely, proportionate and cost-effective adaptation
measures
Why would Europe need high-resolution gridded climate data and products?
Coping with the
unavoidable consequences of climate change
• Climate change a global phenomenon with local impacts, affecting
agriculture, ecosystems, business, industries, water resources, public
health, i.e., people’s daily lives and neighbourhoods
• Spatial heterogeneity of vulnerability to impacts of weather- and
climate-related events such as storms, floods, flash floods, soil
erosion, coastal erosion, landslides, droughts, …
• ”…adaptation measures will be required at regional and local levels to
reduce the adverse impacts of projected climate change and
variability…” (IPCC, 2007)
Conclusions
Showcase EUROGRID results:
• Clearer picture of the EUROGRID-idea
• Demo system,
• using open standards and technologies,
• providing examples of high-resolution gridded data
and products
• There are many promising existing assets
• Need for high-resolution European data
