A webpage displaying a validation of the RCM simulations produced within RT3 is performed for key impact variables here
A webpage depicting
the observation datasets available (and the associated caveats) to
validate the RCM simulations performed over West Africa within the
RT3.5 framewok is available here
Note also that an intercomparison of ERA40-NCEP and CMAP concerning the mean onset date of the WAM
can be viewed here (EMS conference talk, page 9). This highlights the sensitivity of the selected observed reference...
The blue tongue disease
(catarrhal fever) is a non contagious, insect-borne viral disease of
ruminants, affecting mainly sheep and less frequently the cattle.
It is
caused by the bluetongue virus, transmitted by different culicoides
(fly). A significant increase of the disease has been seen since the
last decade over
Northern Europe. This work is a first attempt to
relate climate change (as the virus is temperature driven) and the
possible change in the affected areas over Europe for the
next upcoming
decades, based on the ENSEMBLES RCM simulations and ECA&D observations.
Here is a short report concerning preliminary results.
Validation Atlas for ENSEMBLES RCM runs
This is a link
to a short document including few validation maps
(climatology, variance) for 4 models of the ENSEMBLES RCM database. The
recent climate linear trends are also
highlighted, and few climate
projections are shown (2030-2050 minus 1961-2000). This is done for the
summer (JJA) and winter (DJF) seasons and for 4 impact variables
(Rainfall, Tmean, Tmin, Tmax) over Europe.

Validation Atlas for ENSEMBLES stream1 and DEMETER seasonal forecasts over Africa.
This is a validation atlas of the main African monsoon
features using different validation tools (Mean/Stddev biases,
time series, box and whisker plots, Potential Predictability maps,
correlations, ROC and Brier skill scores...).
The document can be retrieved as a .pdf file here (or click the image below)

An extended list of available observation and simulation dataset achieved in ENSEMBLES
is available through the RT2B regional web portal.
Details and links are also provided in accessing the data on this portal.
Note that you must be registered as an ENSEMBLES partner to access certain datas.
In the following, just find all the usefull links to retrieve the main ENSEMBLES products and other reference datasets.
ENSEMBLES s2d global hindcasts (stream1 and stream2)
The seasonal forecast database is mainly maintained at ECMWF
Details about accessing and downloading the data can be found on the RT1 webpage
The files are publicly disseminated through the (1) MARS archive system maintained at ECMWF (the same link for DEMETER)
(2) OPeNDAP server
Note that a direct download link is now provided.
Read carrefully the conditions of use before downloading the data.
ENSEMBLES anthropogenic climate change (ACC) global simulations (GCM)
These anthropogenic climate change simulations provide anthropogenic and natural forced climate response
for the historical period from 1860 to present and projected response to 2100 for 3 SRES scenario: A2, A1B and B1.
These centennial predictions have been performed with seven different coupled atmosphere-ocean general circulation models
(AOGCMs) of the ENSEMBLES partners:
BCM2 (NERCS-BCCR), CNRM-CM3 (CNRM), ECHAM5/MPI-OM (MPIMET, DMI), EGMAM (FUB)
HadCM3 and HadGem1 (both METO-HC) and IPSL-CM4 (IPSL).
Results from these simulations are reported in the IPCC working group 1 Fourth Assesment report and
provide the focus of ENSEMBLES climate change downscaling activities
Links to data archives:
CERA (central ENSEMBLES ACC GCM archived based in Hamburg, access restricted to ENSEMBLES partners)
ENSEMBLES RT2A (links to the CERA database and others download links, public access)
PCMDI data archives (Registration with IPCC required)
IPCC DDC data archives (public)
Examples of Korn Shell scripts to retrieve the data
Note that a PCMDI/CMIP3 account should be created first...
Note also that kermit sould be installed on your linux/unix system
First download getIPCCfile and place it in you $HOME/bin directory (you must add your username and password in the file)
if the file is not executable type: chmod +x getIPCCfile
Then download and modify retrieve_IPCC.ksh
If the file is not executable type chmod +x retrieve_IPCC.ksh then type ./retrieve_IPCC.ksh to get the datas
By default 25 models are selected.
ENSEMBLES Regional Climate Simulations (RCM)
The RCM runs are mainly archived at DMI and the access is strictly restricted to ENSEMBLES partners.
Historical (20c3m) and climate scenarios (SRESA1B emission scenario) are available.
You can acces the file on the "RCM data overview" section of the ENSEMBLES RT3 webpage
through dods/opendap server or direct download links.
If you do not want to download the files "manually" find here 2 cshell
scripts (linux) to proceed several monthly mean model files:
retrieve_RCM_ctl.csh and retrieve_RCM_a1b.csh
Check that the file are executables otherwise type
chmod +x retrieve_RCM_ctl.csh
./retrieve_RCM_ctl.csh
You'll need wget and gunzip utilities installed on your unix/linux system.
ENSEMBLES Gridded observational data set at high resolution
ECA&D / ENSEMBLES projects. Details can be found on the RT5.1 web page.
4 impact variables are available (T, Tmin, Tmax, Rainfall) at high
resolution (25km2, 50km2, rotated grid) over the period 1950-2006
(European domain).
You need to register (read carrefully the conditions of use) first before accessing the files.

A registration is needed first. To register send an email to Antonio
