Abstract. Past efforts to synthesize and quantify the magnitude change in carbon dioxide (CO2) fluxes terrestrial ecosystems across rapidly warming Arctic–boreal zone (ABZ) have provided valuable information but were limited their geographical temporal coverage. Furthermore, these been based on data aggregated over varying time periods, often with only minimal site ancillary data, thus limiting potential be used large-scale budget assessments. To bridge gaps, we developed a standardized...
Abstract Tundra and boreal ecosystems encompass the northern circumpolar permafrost region are experiencing rapid environmental change with important implications for global carbon (C) budget. We analysed multi-decadal time series containing 302 annual estimates of dioxide (CO 2 ) flux across 70 non-permafrost ecosystems, 672 summer CO 181 ecosystems. find an increase in sink but not despite similar increases uptake. Thus, recent non-growing-season losses have substantially impacted balance...
For the first time, information is summarized on history of establishment, state observations and main scientific results sites included in RuFlux, Russian eddy covariance network for monitoring greenhouse gases (GHG). Eddy technique provides estimates GHG fluxes at level ecosystems. The long-term series (more than 190 site-years observations) have been obtained. Up to end 2022, 86% RuFlux are located forests wetlands, 77% all middle southern taiga. Almost undisturbed ecosystems Russia sinks...
Inter-annual and seasonal variations of energy, vapor water, carbon fluxes associated climate variables in a middle taiga pine (Pinus sylvestris) forest on sandy soils northern larch (Larix gmelinii) permafrost central Siberia were studied from eddy covariance measurements acquired during the growing seasons 1998–2000 2004–2008, respectively. Both pure Scots 215-year-old Gmelin 105-year-old forests naturally regenerated after fires, differed by their tree stand characteristics, grew...
