RCM data archives

This page provides direct links to outputs from the ENSEMBLES, PRUDENCE and DEMETER regional climate model (RCM) simulations.

 

 

ENSEMBLES ACC RCM runs:

These anthropogenic climate-change simulations consist of ENSEMBLES reanalysis (from RT3) and scenario (from RT2B) runs and are archived at DMI. Monthly outputs for these runs (and the PRUDENCE runs) are also available in Climate Explorer. The RT3 ERA40@50 and ERA40@25 RCM European simulations are forced by ERA-40 reanalysis data and have grid resolutions of 50 and 25 km respectively. The RT2B RCM simulations use the same model versions, common domain and grids as the ERA40@25 simulations. They are run for 1950-2050 or 1950-2100 using boundary conditions taken from the ENSEMBLES stream 1 ACC GCM simulations focusing on the SRES A1B scenario.

PRUDENCE ACC RCM runs:

PRUDENCE RCM simulations are also archived at DMI. A PRUDENCE special issue of Climatic Change was published in May 2007. See also the list of publications on the PRUDENCE web site.

ENSEMBLES and DEMETER s2d RCM runs:

These runs are archived at ECMWF in MARS. This system is not public, but asking ECMWF for an account is straightforward.
