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

Description

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).

Steps to reproduce

CO₂ exchange fluxes were measured in the field using a closed-chamber method and a Q-Box CO650 gas analyzer under light and dark conditions. Measurements were conducted repeatedly throughout the growing seasons in 42 collars distributed across eight raised bogs. Environmental and vegetation variables were recorded concurrently at each measurement.
