ClimGen data for the TOPDAD project
About ClimGen scenarios
ClimGen scenarios are constructed by scaling patterns of climate change by a gradually changing global-mean temperature, to represent the gradually changing climate signal. This is then superimposed on the observed mean climatology. Finally, observed monthly anomalies are superimposed, to represent a plausible sequence of climate, combining a gradually changing climate that begins from observed values with one possible sequence of climate variability.
The output files, provided as yearly values or as 5-year, 10-year and 30-year means, thus include one possible sequence of variability. Even for a scenario that is monotonically increasing, the climate may still show some fluctuations up and down due to this variability. If partners wish to use an ensemble of multiple scenarios, each with a different sequence of climate variability, then we can produce an ensemble with ClimGen.
The version of ClimGen used to make the TOPDAD is v1-22. See the main ClimGen webpage for further information about ClimGen.
The data files (and in some case, graphics files containing figures) are grouped according to the structure below. It is essential to read the log, latest entry first, for each group so that you are aware of errors, updates, caveats etc.
When you click on the link to each group of files, you will then be able to download them manually or with automated software such as wget. Some files are in zip files to make downloading quicker.
All data files are text (i.e., ASCII) files. The layout of the contents is fairly self-explanatory. Descriptions of the file format and the file naming system are available on the main ClimGen webpage.
Log -- please check this for updates, corrections, etc.
