Modellers deplore 'short-termism' on climateThe PRUDENCE participation in the recent workshop in Lund 29/3-2/4 "High-resolution climate modelling: Assessment, added value and applications" made it as a news item in Nature, 428, 593, by Quirin Schiermeier. Some quotes: "We're not yet at the promised level where regional climate models can really influence policy-making," Georgios Amanatidis, a scientific officer at the European Commission's research directorate, told the meeting. "If you don't believe in the value of global climate models then there's no point in downscaling them," says Filippo Giorgi, an atmospheric physicist now at the ICTP in Trieste, Italy]. "But if you do - and global models do provide a quite consistent pattern of climate change - then it makes sense to translate global patterns into local information." Thanks to Prudence, Europe is currently leading the field, Giorgi adds. "There is quite some envy over here of how well things are organized and funded in Europe," says Francis Zwiers, head of the Canadian Centre for Climate Modelling and Analysis in Victoria,British Columbia. American and Canadian modellers are seeking funds for a similar collaboration of their own. "This would really come at the right time," says René Laprise, principal investigator at the Canadian regional climate modelling group in Montreal, "now that we are finally understanding what we're doing - some of the time!"

27/3/2008:
The file evap.HC.adhfa.2070-2100.nc.gz has been replaced due to some errors (in one month).
19/12/2007:
The site has been down since yesterday due to an upgrade of the disk system. We are up again, but the restoration of the entire data archive is expected to last at least a week. We apologize for your inconvenience!
11/7/2007:
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 prudencerestricted.dmi.dk 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.
19/4/2007:
The missing ETH Psurf data have not been put into the archive.
18/1/2007:
The DMI 12km daily data are now online. Recall that this is a standard PRUDENCE simulation with 4 times the resolution,
using the Baltic SST's from the RCAO simulation. This means that this pair, F12/S12, corresponds to the HC1/HS4 simulation pair in 50km resolution. Note that each field is split into
3 decadal files with indices corresponding to the decade. Direct download from
http://prudence.dmi.dk/data/daily/DMI/F12
and DODS download from http://ensemblesrt3.dmi.dk/cgi-bin/nph-dods/data/prudence/daily/DMI/F12/
and correspondingly for S12.
13/10/2006:
An inconsistency in the SMHI files for t2min and t2max has been identified.
The data in each field of these files belongs to the previous day (D-1)
instead of the actual day (D). As a consequence t2m(D) (the daily mean
temperature) is not always in the range [t2min(D),t2max(D)] which it
should be.
14/8/2006:
A few updates: Some Hadley Centre manuscripts have been added to the publications list. Some corrupted orography/lsm files have been repaired. And most importantly: The accepted manuscripts for the special PRUDENCE issue of Climatic Change are now accessible here.
7/6/2006:
Erroneous coordinates in the HIRHAM scenario B2 data (HB1) have been corrected. The data were OK but pertained to the coordinates in the standard HIRHAM grid.
25/4/2006:
An error has been found in the HIRHAM Greenland data (ARA, ARB, and ARC) that are stored on this server, part of the Nordic project Climate and Energy. The evaporation fields were a factor of 3 too small. This has been corrected today. Sorry!
16/3/2006:
For the first time in a very long while there are new data at the site. A global atmospheric 25km run made by the Japanese Meteorological Research institute (MRI) has been put up in directories MRI_JMA. We have clcov, evap, radiation fluxes, MSLP, Psurf, q2m, snow, soilw and t2m for a control experiment and for 2071-2100 from an A1B scenario on the original grid in the database, over an area covering the PRUDENCE region of interest. Thanks!
14/3/2006:
After about a month of uploading files, the PRUDENCE site has been reopened after a disk crash on the old server. I believe that the
files are OK now, but it is human to err. So, please,
13/9/2005:
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:

The Lund meeting 29/3-2/4 2004 now has a home page (at least I did not know about it till now...) with all presentations there for download.
24/2/2005:
I have received the following from Dave Rowell at the Hadley Centre:
As some of you will remember, Phil Graham found that the surface moisture budget did not balance in the Hadley Centre data submitted to the PRUDENCE archive. We have now finally made significant progress with resolving this problem, and have found that the daily surface runoff fields contain erroneous values. (The actual data in the archive is the sum of the surface and sub-surface runoff). We suspect that it may be due to a problem with the packing of the data, but are still investigating this. In any case, it is most unlikely that it will be possible to apply any kind of correction to these fields. However, there is some good news, which is that the problem does not affect other meaning periods, such as monthly means (these are made while the model runs, and not made from the archived daily data).
Therefore we must withdraw all daily runoff data in the PRUDENCE archive for all Hadley Centre models, including the monthly means that Ole has made from them. We will however submit in it's place the monthly mean runoff fields referred to above. We all at the Hadley Centre sincerely apologise for this, and acknowledge the inconvenience it will cause some of you.
We hope that the monthly mean data will be sufficient for all/many of you that require runoff? However, if the absence of reliable daily runoff data causes anyone major problems, please let us know.
15/2/2005:
The PRUDENCE final report has been finished and can be downloaded
from here. Furthermore, in connection with the COP10 meeting, a document with
country-by-country climate projections has been made by Jens.

PRUDENCE is 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.
