Effective temperature sums and durations of the vegetative period in Fennoscandia (1921-1950)
Maps present the beginning, the end, the duration and the effective temperature sum of the vegetative period which denotes the duration of daily, mean, screen air temperatures of 5°C or more calculated from observations over period of 30 years. The maps are reduced to sea level, to rural condition...
