At Čertovo Lake in Bohemia, mean daily and monthly air temperatures were reconstructed back to 1961 and 1781 respectively, using daily data from Churáňov (Bohemian Forest) and monthly data from Hohenpeissenberg (Germany). Daily air temperatures varied between -17.7 degrees C and 23.2 degrees C in the 1961-2001 period, with an average of 3.8+-0.7 degrees C (+- mean error). Mean monthly air temperatures were predicted with mean absolute error of 0.5 degrees C and varied from -12.0 to 16.2 degrees C in the 1781-2001 period, with long-term averages between -5.3 degrees C in January and 12.3 degrees C in July-August. Mean annual air temperatures varied between 2.1 degrees C and 5.1 degrees C, with the 1781-2001 average of 3.4 degrees C. Long-term trend in mean annual air temperature exhibited 3 distinct periods: (i) fluctuation along the 1781-2001 average between 1781 and 1830, (ii) colder period from 1830 to 1940 and (iii) increasing temperature since the 1960s, with the most rapid increase between 1980 and 2001.
