CO₂ exchange fluxes in raised bogs of Southern Patagonia (Tierra del Fuego, Argentina)

This dataset contains raw CO₂ exchange flux measurements collected in raised bogs of Southern Patagonia (Tierra del Fuego, Argentina), during the growing seasons of 2021–2022 and 2022–2023. Measurements were conducted across contrasting microforms (hummocks and lawns) under light and dark conditions in eight raised bogs and 42 permanent collars, measured repeatedly throughout the growing seasons. The dataset includes net ecosystem exchange (NEE) and associated environmental and vegetation variables measured during each flux assessment, including air temperature, chamber temperature, soil temperature at 10 cm depth, water table level, vascular plant cover, and photosynthetically active radiation (PAR).
