Daily mean (s.d.) and minimum–maximum air temperatures (Tair; °C) and relative humidities (RH; %) for individual months of the 2010 and 2011 growing seasons inside glass domes with ambient (AC) and elevated (EC) CO2 concentrations. Sums of precipitation (Psum; mm) originate from a nearby meteorological station. Measurements were made automatically at 10-min frequency
