Data for constructing climate scenarios

GCM outputs

• IPCC scatter plots of multi-GCM 30-year average, seasonal temperature and precipitation projections in the 21st Century for 32 IPCC world regions (link to the documentation,  scatter plots and underlying data) 
• Outputs from experiments forced by the SRES emissions scenarios and peformed with 9 GCMs assessed by the IPCC Third Assessment Report (TAR) (link to the data archive)  
• Outputs from experments forced by the SRES emissions scenarios and incremental emissions scenarios performe with 23 GCMs assessed by the IPCC Fourth Assessment Report (AR4) (link to the data archive)   

GCM outputs processed for use with the Statistical DownScaling Model (SDSM)

• Daily outputs for common large-scale air flow indices simulated by HadCM3 and CGCM1 to be directly used with the Statistical DownScaling Model (SDSM) prepared by the Canadian Institute for Climate Studies (CICS) (access the data)
