TABLES AND FIGURES
Table 1: Climatic variables of the three study sites. They include: average annual precipitation (mm), seasonality (number of months in which the precipitation is less than 100 mm), mean maximum temperature (°C), mean minimum temperature (°C), absolute minimum temperature (°C), number of frost events (number of days in which temperatures lower than 0°C) and frost hours (number of hours in which the recorded temperature is less than 0°C). These data were collected for 2013 (year in which we conducted the measurements) from the database of the General Directorate of Water (DGA) of Chile.
