IPCC 4th Assessment Report (2007): Scenario 20C3M

Scenario: 20C3M

Simulations of the 20th centuryMore details on scenarios here.

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)
The averaging period is relative to AD2000 for SRES scenarios A1B, A2 and B1, relative to AD1900 for the twentieth century run (20C3M) and relative to the start of the experiment for the pre-industrial control (PICTL) and the 1PCTO2X and 1PCTO4X runs.
