  1. Sources of Climate Information and the WB Climate Data Portal Michael I. Westphal CC Team ENV SDN Week 26/2/08

  2. Oft-heard Questions • What’s out there? • What data are easily accessible? • What data are useful and important in the development context? - timeframe, variables, spatial scale (Are GCMs too coarse?) • Is it all too uncertain? (Or the Paralysis of Uncertainty)

  3. Sources of Climate Information I.) Documents/ Reports • IPCC Fourth Assessment Report (www.ipcc.ch) • Limitations: - Informational only, no data - Generated by and for (?) climate scientists - Qualitative, difficult to bore down to regions - Most projections end of 21st Century

  4. II) Data Sites • IPCC Data Portal (WCRP CMIP3 multi-model database) (https://esg.llnl.gov:8443/) - abstruse (netCDF) format, unusable to development professionals

  5. II) Data Sites • Various CRU historical datasets Tyndall: http://www.cru.uea.ac.uk/~timm/data/index-table.html CGIAR: http://cru.csi.cgiar.org/CRU_data_structure.asp University of East Anglia http://www.cru.uea.ac.uk/cru/data/ -requires programming/GIS sophistication

  6. II)Data Sites • WorldClim (www.worldclim.org) - Historical bioclim variables ands downscaling from 3 GCMs (IPCC 3AR) -no measures of extreme precipitation; rainfall variability -requires programming/GIS sophistication

  7. III) Visualisation Sites • Hadley Centre -One model, one point in time, limited variables (http://www.metoffice.gov.uk/research/hadleycentre/models/modeldata.html) • National Center for Atmospheric Research - More variables, more interactive but still one point in time - can download data - one model - missing variables to development? (rainfall variability, variability, variability) (www.gisclimatechange.org)

  8. III) Visualisation Sites – Current/historical climate • International Research Institute for Climate and Society – climatologies, drought, anomalies, etc. (http://portal.iri.columbia.edu/portal/server.pt) • NOAA Africa Desk - climatologies, drought, anomalies, station data, etc.(http://www.cpc.ncep.noaa.gov/products/african_desk/)

  9. IV) What about “desktop” models? • MAGICC (http://www.cru.uea.ac.uk/~mikeh/software/magicc.htm) -More for exploring emissions; only basic temp and SLR • PRECIS (Hadley Centre) - (http://precis.metoffice.com) - More for Met Bureaus -A typical experiment (100 x100 grid) run on a 2.8GHz machine: 4.5 months to complete a 30-year simulation!

  10. … hence the need for a Climate Data Portal

  11. Niche of our Climate Data Portal • ‘Light’ and quick, ease-of-use • Visualization, querying, data summarization • Pixel-level and country aggregation • More consonant with development timeframe and variables (extreme precipitation/ temperature) http://essdcharts.worldbank.org

  12. Niche of our Climate Data Portal • Historical and Projected • GCMs and downscaling • Multimodel, model concordance/discordance (uncertainty) • Not just 1 Climate Data • - Climate-related (natural disaster, crop yield projections) • - Non-climate (socioeconomic)

  13. Some Global Datasets

  14. Some Global Datasets

  15. Planned Functionality • Linkages with other tools, wiki • Interfacing with Bank databases • Spatially-referenced Knowledgebase

  16. Acknowledgements • Data suppliers: - IPCC Data Portal (LLL) - MRI, Japan • SDN IT Group - Reza Firuzabadi - Arvind Gowda, Dany Jones, Michael Kane, Ritesh Sanan, Varuna Somaweera

  17. Climate Needs for Bank? • Variables • Spatial Scale • Time Frame • Display of uncertainties • Format • Will this portal be useful? When? Modifications, extensions?
