1. CLIMATE Action
Implementation of methodological tools and techniques
to develop the climatology of the Pyrenees
POCTEFA - EFA 235/11
Pyrenees Climate Change Observatory
(OPCC)

2. CLIMATE Action - OPCC
MAIN PARTNERS:
Universidad de Zaragoza (UNIZAR, Aragon)
Servei Meteorològic de Catalunya (SMC-Meteocat, Catalonia)
ASSOCIATED PARTNERS:
MétéoFrance (France)
Centre d’Estudis de la Neu i la Muntanya d’Andorra (CENMA, Andorra)

3. CLIMATE ACTION - OBJECTIVES
1. Share available meteorological (raw) data in the area (Pyrenees).
2. Use the same methodology for data processing (Action COST ES0601).
(HOME - Advances in homogenization methods of climate series: an integrated approach)
3. Develop an unique database of high quality climate series at the Pyrenees.
4. Obtain a basic climatology (based on T/PPT) of the Pyrenees (1950-2010).

4. TEMPERATURE STATIONS LOCATION

5. HOMOGENIZATION PROCESS
1. Detecting “aberrant” data (Quality Control)
2. Finding optimal neighbours

6. HOMOGENIZATION PROCESS
3. Detecting break-points and filling gaps with correlated homogeneous data

CURRENTLY WORKING: PRECIPITATION

13. FUTURE WORK
Finish currently work on T and PPT (trend analysis, indicators to monitor
climate evolution, …).
Strengthen the network in climate studies at the Pyrenees (universities,
research centers and meteorological services).
Increase the climate evolution studies with other variables (esp. snow
cover or snow depth).
Develop or improve knowledge about future climate scenarios at the
Pyrenees.
