Application of a balanced identification method for gap-filling in CO2 flux data in a sphagnum peat bog

Abstract: В работе рассматривается применение метода сбалансированной идентификации для построения многофакторной функциональной зависимости нетто СО 2-обмена (NEE) от факторов внешней среды и ее дальнейшего использования для заполнения пропусков в рядах наблюдений за потоками СО 2 на верховом сфагновом болоте в Тверской области. Измерения потоков на болоте проводились с помощью метода турбулентных пульсаций в период с августа по ноябрь 2017 года. Из-за дождливых погодных условий и высокой повторяемости периодов с низко… Show more

“…gets using the gap-filled time series. Partitioning of the NEE into GPP and ER is also needed for better understanding of interannual and spatial variability of the carbon fluxes (Sokolov et al 2019). The fundamental ecosystem processes (including photosynthesis and respiration) are common to mires and other terrestrial ecosystems, so changes in photosynthetically active radiation (PAR), air temperature (Ta), and precipitation may affect the C cycle in peatlands, e.g.…”
