- Аннотация: The continuous measurement of CO 2 fluxes at the open-top chamber experiment in the ombrotrophic peatland (located in the middle taiga zone, West Siberia, Russia) has been provided during the warm season of 2022 (beginning of June to beginning of October). The R eco , NEE and GPP were calculated for this period; abiotic factors related to CO 2 emissions, such as PAR, air temperature, water table level and precipitation, were also measured. The monthly average values showed a negative NEE of -9.89 C g m -2 month -1 in July, a negative GPP of -34.19 C g m -2 month -1 in July, and a positive values R eco of 41.68 C g m -2 month -1 in August. In 2022, the studied peatland hollows were only a carbon stock in July, while in the remaining months they were a source of CO 2 , which could be caused by small precipitation amount. The monthly average diurnal variations of CO 2 fluxes showed similar behaviour for both the OTC plot and control plot fluxes, which may be explained by the similarity in vegetation cover.
