<!--!introduction!--> This observational study provides variations of surface fluxes and other ancillary atmospheric/surface/soil data based on in-situ measurements made at Mukhrino field station located at in the middle taiga zone of the West Siberian Lowland. Turbulent fluxes of momentum, sensible and latent heat, CO2 and СH4 were measured with the EC technique. Measurements in the atmosphere were supplemented by measurements of heat flux through the soil, radiation balance and soil temperature at several levels and atmospheric boundary layer structure and dynamics. Most of the available energy is released as latent heat flux, while maximum sensible heat fluxes are more than 3 times lower. Net CO2 sink was comparatively high but was typical for a wetland area. Measurements show that the swamp is a source of methane. There is a gradual increase in the methane flux during the period under consideration, which is probably associated with soil heating. At night, the methane flux becomes smaller in absolute ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
