Study Site: Arctic–boreal regions
Purpose: Unprecedented warming of Arctic–boreal regions (ABR) has poorly understood consequences on carbon cycle processes. Limited winter data add uncertainty to annual methane (CH4) budgets. In this study, winter CH4 flux measurements were conducted using the snowpack diffusion gradient method over five ABR ecosystem types in Canada and Finland: closed–crown and open–crown coniferous boreal forest, boreal wetland, erect–shrub and prostrate–shrub tundra.
Abstract: Non-growing season CH4 fluxes over boreal and arctic environments using the snowpack diffusion gradient method. This dataset consists of 802 snowpack diffusion gradient measurements made over five different boreal and arctic ecosystems in Canada and Finland: closed-crown coniferous boreal forest, open-crown coniferous boreal forest, erect tundra shrubs, prostrate tundra shrubs and boreal wetlands. Snow and soil data are incorporated into the dataset as environmental variables.
