SHOWCASE EUROGRID

Is there a need for a European core service component forhigh-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 EUROGRID-concept 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 ServicesPart 2: DataView (Time series from SQL-database)

• Data visualization

• Extraction of data at grid points from MySQL5-database by mouse-click

• Plot of time-series

• XHTML-table

• Data dissemination

• XHTML-table

• Other formats (to be implemented if desired)

• http://www.e-grid.eu/products/ (still restricted)

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
