Final Report of the ENSEMBLES Project

ENSEMBLES (Ensemble-based Predictions of Climate Changes and their Impacts):
The project aims to develop a regional ensemble prediction system for sesonal to interannual prediction (focusing on climate change) based on the principal state-of-the-art, high resolution, global and regional Earth System models developed in Europe, to produce for the first time, an objective probabilistic estimate of uncertainty in future climate at the seasonal to decadal and longer timescales. It also aims to maximise the exploitation of the results by linking the outputs of the ensemble prediction system to a range of applications, including agriculture, health, food security, energy, water resources, insurance and weather risk management.

Key Achievements of the project:

Contribution of the Santander Meteorology Group:
Our group contributes to RT2B in the following workpackages:

  • WP2B.2 (development of new methods for the construction of probabilistic regional climate scenarios based on output from RCMs and GCMs).

  • WP2B.3 (application of new methods for the construction of probabilistic high-resolution regional climate scenarios), focusing on the application of the new tools developed in WP2B.2 to output from RCMs (WP2B.1) and GCMs (RT2A).
  • Web portal for regional downscaling http://www.meteo.unican.es/ensembles.

The above two tasks will thus provide data inputs for the selected impacts studies in RT6 and probabilistic climate scenarios for study regions and Europe as a whole, for mean climate parameters and impact relevant indices including indicators of extremes (which will also be useful for impact studies not incorporated in ENSEMBLES). Application of these methods will also provide information on the most important sources of uncertainty in the final regional climate scenarios, which will be an important feedback to the climate modelling activities in ENSEMBLES (i.e., RT1, RT2A and RT3).
