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).

HOMOGENIZATION PROCESS

1. Detecting “aberrant” data (Quality Control)

2. Finding optimal neighbours

CURRENTLY WORKING: PRECIPITATION

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.
