Spatio-temporal changes in variability of temperature, precipitation and runoff in Finland during the period 1962-2014
This study assesses spatio-temporal changes in inter-annual variability of temperature, precipitation and runoff for 1962-2014 at sub-basin scale in Finland. The analysis is based on 1) interpolated areal average temperature and total precipitation based on corrected observations, and 2) modelled ru...
