ClimatePrediction.net model runs on worldwide personal computer network

The Climateprediction.net project is harnessing the spare CPU cycles of tens of thousands of individual users' PCs to run a massive ensemble of climate simulations using the Met Office's Unified Model. A multi-thousand member ensemble of simulation results from the perturbed physics climate sensitivity experiment is available for research purposes.

Distribution format

Name	Version
Availability of data and file format The data is divided into a series of volumes with a consistent directory structure. Volumes are filled in the order data is submitted and therefore a single volume may contain simulations from multiple Climateprediction.net experiments. The first volume in the dataset (vol-000) is a quality controlled subset of early Climateprediction.net data that is documented seperately here. This volume contains aproximately 2500 runs with a total size of 13Gb. Subsequent volumes will be an order of magnitude larger. Each simulation is stored within a volume at a URL matching the following pattern: ftp://ftp.ceda.ac.uk/badc/cpdn/volumes/vol-xxx/model/yy/result-name Where xxx is a zero-padded volume number, model identifies the type of Climateprediction.net simulation (e.g. standard for the HadSM3 slab model experiment or sulphur for the HadSM3 + sulphur cycle experiment) and yy is a directory branch designed to limit the size of individual directories. The directory branch yy is currently calculated as the first 2 characters of the simulation's UM id, which is usually also part of the result-name. However, this feature should not be assumed as future volumes may use a different convention. Within each simulation directory data is stored as a series of NetCDF files conforming to the CF metadata standard.

Availability of data and file format

The data is divided into a series of volumes with a consistent

directory structure. Volumes are filled in the order data is submitted and

therefore a single volume may contain simulations from multiple

Climateprediction.net experiments.

The first volume in the dataset (vol-000) is a quality controlled subset of early Climateprediction.net data that is documented seperately here. This volume contains aproximately 2500 runs with a total size of 13Gb. Subsequent volumes will be an order of magnitude larger.

Each simulation is stored within a volume at a URL matching the following pattern:

ftp://ftp.ceda.ac.uk/badc/cpdn/volumes/vol-xxx/model/yy/result-name

Where xxx is a zero-padded volume number, model

identifies the type of Climateprediction.net simulation

(e.g. standard for the HadSM3 slab model experiment or

sulphur for the HadSM3 + sulphur cycle experiment) and

yy is a directory branch designed to limit the size of

individual directories. The directory branch yy is currently calculated

as the first 2 characters of the simulation's UM id, which is usually

also part of the result-name. However, this feature should not

be assumed as future volumes may use a different convention.

Within each simulation directory data is stored as a series of NetCDF files conforming to the CF metadata standard.
