The recent decline in forest carbon (C) sink across the Nordic countries has been partly attributed to increased water limitations, that is, droughts, on forest productivity. However, empirical evidence for this remains limited. This study combines ERA5‐Land reanalysis datasets with long‐term C and water flux observations from Swedish and Finnish coniferous forest eddy covariance (EC) towers to assess the conditions under whic...

Rewetting drained peatland forests restores pristine ecosystem functions, improves peatland ecological status, and has been considered to mitigate climate change. We quantified climate impact of rewetting boreal peatland forests in Northern Europe by comparing the radiative forcing of alternative restoration pathways to that of continued forestry use. We considered changes in soil carbon dioxide, methane and nitrous oxide bala...

Information on terrain conditions is a prerequisite for planning environmentally and economically sustainable forest harvesting operations that avoid negative impact on soils. Current soil data are coarse, and collecting such data with traditional methods is expensive. Forest harvesters can be harnessed to estimate the rolling resistance coefficient ( $$\mu _{RR}$$ μ RR ), which is a proxy for forest trafficability. Using spat...

The terrestrial net ecosystem productivity (NEP) has increased during the past three decades, but the mechanisms responsible are still unclear. We analyzed 17 years (2001–2017) of eddy‐covariance measurements of NEP, evapotranspiration (ET) and light and water use efficiency from a boreal coniferous forest in Southern Finland for trends and inter‐annual variability (IAV). The forest was a mean annual carbon sink (252 [42] gC )...

Earth observing systems are now routinely used to infer leaf area index ( LAI ) given its significance in spatial aggregation of land surface fluxes. Whether LAI is an appropriate scaling parameter for daytime growing season energy budget, surface conductance ( G s ), water‐ and light‐use efficiency and surface–atmosphere coupling of European boreal coniferous forests was explored using eddy‐covariance ( EC ) energy and CO 2 f...
