Abstract: Andorra has three historical climate series of temperature, precipitation and snow thickness recorded by FEDA (Forces Elèctriques d'Andorra, in his moment FHASA), since September of 1934 in three different sites: Central Encamp (1,145 m), Engolasters (1,640 m) and Ransol (1,640 m). These observations record series of continuous 83 years, one of the longest in the Pyrenees and covering the last three international climatic periods. Within the framework of the CLIM'PY project (Interreg V - POCTEFA), whose objective is the analysis of climate change in the whole of the Pyrenean massif, an exhaustive work of quality control and analysis of the databases daily scale as well as the homogenization of the series on a monthly and daily scale. This work describes the behavior and the evolution of the principal snow variables in Andorra: snow thickness and snow duration. On one hand, based on the daily-accumulated snow thickness series, the analysis focuses on the seasonal and annual values obtained from the total thickness and the number of days with snow on the ground. On the other hand, the analysis of the series also aim to detect the existence of a statistically significant climate trend, both in the snow precipitation and the duration of the snowpack and deepen in the possible effects of Climate Change on nivological variables.
