IPCC 4th Assessment Report (2007): Scenario COMMIT
Scenario: COMMIT
An idealised scenario in which the atmospheric burdens of long-lived greenhouse gasses are held fixed at AD2000 levels.More 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.
