Statistical and Regional dynamical Downscaling of Extremes for European regions
A research project supported by
the European Commission
under the Fifth Framework Programme
and contributing to the implementation of the Key Action
"Global change, climate and biodiversity"
within the Environment, Energy and Sustainable Development.
Contract no: EVK2-CT-2001-00115
February 2002 to July 2005
Co-ordinated by Dr Clare Goodess, Climatic Research Unit
STARDEX will provide a rigorous and systematic inter-comparison and evaluation of statistical, dynamical and statistical-dynamical downscaling methods for the construction of scenarios of extremes.
The more robust techniques will be identified and used to produce future scenarios of extremes for European case-study regions for the end of the 21st century.
These will help to address the vital question as to whether extremes will occur more frequently in the future.
STARDEX 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 and PRUDENCE. This research is highly relevant to current climate related problems in Europe.

STARDEX Diagnostic Extremes Indices Software
Version 3.3.1 updated 2nd June 2004. See documentation for version history.
This software calculates 57 annual and seasonal extremes indices
(such as percentiles, growing season length and wet/dry day duration)
from daily temperature and precipitation time series.
It is provided free of use.
The two software elements (a Fortran subroutine that calculates all
the indices for a single location and a Fortran program that uses this
subroutine to process station data in a standard input format)
are accompanied by a user information document.
- Indices: STARDEX core extremes indices calculated for 491-station European data set
- Downscaled series: Calculated from NCEP data as well as control and perturbed GCM experiments - available here

The following data sets are available from other organisations and projects and are likely to be of use to STARDEX participants.
In some cases, registration may be needed before a data set can be downloaded or used and restrictions of use may apply.
STARDEX participants should quote the project name/funding body/contract number where appropriate.
Data sets which are restricted to the STARDEX consortium are available from the internal pages.
The following datasets are provided from the STARDEX data repository:
