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)
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
II) Data Sites

IPCC Data Portal (WCRP CMIP3 multimodel database)
(https://esg.llnl.gov:8443/)
- abstruse (netCDF) format, unusable to
development professionals
II) Data Sites
 Various CRU historical datasets
Tyndall:
http://www.cru.uea.ac.uk/~timm/data/indextable.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
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/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)
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_des
k/)
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!
… hence the need for a Climate
Data Portal
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
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)
