Anomalies
For the SRES scenarios, SRA1B, SRA2, SRB1, anomalies are calculated relative to the 1961-1990 mean of the 20th century simulation, 20C3M. Anomalies for the 1PTO2X and 1PTO4X scenarios are relative to the pre-industrial control, PICTL.Further details

Data Tables
Each block in the table contains links to one or more data files and to one information page (the `info' link) with further information. The data files are 'tar' files with names of the form [model]_[scenario]_[variable]_[climatology].tar. The model, scenario and variable are determined by the position in the table. Each tar file contains several NetCDF files with names of the form: [model]_[scenario]_[ensemble number]_[variable]_[start-year]-[end-year].nc. Different climatologies are indicated by the links within each table entry.- 20x: Twenty year averages, +20-39, +46-65, +80-99, +180-199 (as used in Chapt. 10 of IPCC 2007)
- 30a: Thirty year averages, +01-30, +31-60, +61-90 (as used in the observational climatologies)
- 30b: Thirty year averages, +10-39, +40-69, +70-99 (for compatibility with the 3rd Assessment Report)
