PRUDENCE and what came after


PRUDENCE ended in 2004. The next EU-financed major effort in regional climate modelling was the ENSEMBLES project, financed under Framework Programme 6. A major archive of data in 25km resolution covering the transient periods 1951-2100 or 1951-2050 according to the SRES A1B scenario is available at the DMI -Actually at the same physical machine as this PRUDENCE page.

ENSEMBLES ended in 2009; immediately a new major project was started up: CORDEX, which is an international WCRP project without funding. The CORDEX archive is set up in the ESGF infrastructure known from CMIP5. One access point is here. There is a lot of data, and the archive is still growing (updated 20150819). Read more about CORDEX in the links at this page.

18/9/2014 OPeNDAP functionality is back. Note that the URLs are different from before.


We are now running again on a new server. Sorry for your inconvenience! Let me know if you run into any technical glitches.


As you are probably aware, this archive has been having huge performance problems for a while. We now believe that we have found one reason, and this reason is one particular user. I will give some details below, not to place blame, but to inform you all how NOT to do.

Somebody, a Mac user probably from Italy, has been using a download manager called iGetter to access data files at This is of course OK. The problem is that this piece of software starts a number of parallel downloads. The setup of this user started a number so large that we hit the ceiling of the apache server here, basically excluding the rest of the world.

It is probably not this particular user and program who is responsible for all the downtime, but he/she certainly has been a major part of the cause this week. Please, all users, be aware that parallel downloads may give you better access time now; but you are in fact taking the bandwidth from other users. Next time you will be the one unable to get through. So, be nice!

Two important updates: The special issue of Climatic Change (Vol. 81 2007) concerning the PRUDENCE project is now available. And, I have removed the participants-only data from this server. This means that just points to this page. If you REALLY need the data, and if you are allowed (you probably are not...), then write me a mail.

Plots of the biases and climate signals have been made public and are available as follows: The organization of the plots is explained here.

Also climate change maps are present:

PRUDENCE (2001-2004): Project EVK2-CT2001-00132 in the EU 5th Framework program for Energy, environment, and sustainable development.

PRUDENCE (2001-2004) was a European-scale investigation with the objectives:

PRUDENCE is part of a co-operative cluster of projects exploring future changes in extreme events in response to global warming. The other members of the cluster are MICE (Modelling the Impact of Climate Extremes) and STARDEX (Statistical and Regional Dynamic downscaling of Extremes for European regions). This research is highly relevant to current climate related problems in Europe. To find out more visit the MPS Portal.
