The study of historical climatic data in the Pyrenees mountain range could help with forecasting future climatic conditions to fight water deficit in region of Catalonia (North East Spain). However, the limitations in obtaining historical data series from high elevation areas increase the difficulty and complexity on studying its variability of climate. To overcome these challenges, further exploration is needed. For the purpose of this study, climatic data from meteorological stations located in the Pyrenees was gathered to study the role of elevation on precipitation, evapotranspiration and temperature patterns.
