Air temperature changes in Żagań (Poland) in the period from 1781 to 1792
Abstract The temperature measurements in Żagań were made within the Mannheim network of stations established for Europe and North America by the Palatine Meteorological Society in 1780. The meteorological observations made there in the period 1781–1792 were taken according to the rules for observers...
