Publikováno v: Biogeosciences, Vol 19, Pp 3151-3167 (2022)

Arctic tundra is facing unprecedented warming, resulting in shifts in the vegetation, thaw regimes, and potentially in the ecosystem–atmosphere exchange of carbon (C). However, the estimates of regional carbon dioxide (CO2) and methane (CH4) budget

Interpreting eddy covariance data from heterogeneous Siberian tundra: land-cover-specific methane fluxes and spatial representativeness

Autor: J.-P. Tuovinen, M. Aurela, J. Hatakka, A. Räsänen, T. Virtanen, J. Mikola, V. Ivakhov, V. Kondratyev, T. Laurila

Publikováno v: Biogeosciences, Vol 16, Pp 255-274 (2019)

The non-uniform spatial integration, an inherent feature of the eddy covariance (EC) method, creates a challenge for flux data interpretation in a heterogeneous environment, where the contribution of different land cover types varies with flow condit

Subsea permafrost and hydrates in the East Siberian Arctic Shelf (ESAS) constitute a substantial carbon pool, and a potentially large source of methane to the atmosphere. Previous studies based on interpolated oceanographic campaigns estimated atmo

Publikováno v: Atmospheric Chemistry and Physics, Vol 16, Pp 1271-1287 (2016)

Four years of continuous aerosol number size distribution measurements from the Arctic Climate Observatory in Tiksi, Russia, are analyzed. Tiksi is located in a region where in situ information on aerosol particle properties has not been previousl
