Two-decade variability of climatic factors and its effect on the link between photosynthesis and meteorological parameters : example of Finland's boreal forest
Climate and forests are linked to each other via sophisticated feedback mechanisms. Recognizing the complexity of atmosphere-biosphere interactions, here we use a simplified approach aiming to establish connections between the parameters characterizing the boreal forest as a carbon sink and meteorol...

Climate and forests are linked to each other via sophisticated feedback mechanisms. Recognizing the complexity of atmosphere-biosphere interactions, here we use a simplified approach aiming to establish connections between the parameters characterizing the boreal forest as a carbon sink and meteorological parameters using a two-decade data set (1996-2017) from the Station for Measuring Ecosystem - Atmosphere Relations (SMEAR II), Finland. First, we quantify climate changes in Finland using growing season length and climatic indices.
