Daily values of weather observations
The data contains calculated and measured daily values from the Finnish Meteorological Institute's weather observation stations starting from 1844. Calculated values are the daily average air temperature and the daily precipitation. The measured values are minimum and maximum air temperature, minimum ground temperature and snow depth. The extremes of the air temperature are measured at 06 and 18 UTC and the minimum ground temperature at 06 UTC. These represent extreme values over the last 12 hours (18-06 and 06-18 UTC).
