Title: Sources of Climate Information and the WB Climate Data Portal


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
  • Whats 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.gov8443/)
  • - abstruse (netCDF) format, unusable to
    development professionals

6
  • II) Data Sites
  • Various CRU historical datasets
  • Tyndall http//www.cru.uea.ac.uk/timm/data/inde
    x-table.html
  • CGIAR http//cru.csi.cgiar.org/CRU_data_structur
    e.asp
  • University of East Anglia http//www.cru.uea.ac.u
    k/cru/data/
  • -requires programming/GIS sophistication

7
  • 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

  • III) Visualisation Sites
  • Hadley Centre
  • -One model, one point in time, limited variables
  • (http//www.metoffice.gov.uk/research/hadleycentr
    e/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)

  • 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/)

  • IV) What about desktop models?
  • MAGICC (http//www.cru.uea.ac.uk/mikeh/software/m
    agicc.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!

16
hence the need for a Climate Data Portal
17
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

18
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)

19
Some Global Datasets
Type Variables Institute Resolution
Climate Change Projections (High resolution GCM) Temp, Precip, extreme rainfall metrics Meteorological Research Institute, Japan 20 km.

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

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