CO₂ and CH₄ fluxes and energy balance at the Kopytkowo eddy-covariance site (Biebrza National Park, northeastern Poland), 2013–2024
收藏资源简介：
The file PL_Biebrza_Kopytkowo_fluxes_2013_2024.csv contains monthly mean values of eddy-covariance greenhouse gas fluxes and associated meteorological variables collected at the Kopytkowo eddy-covariance site (53°35'30.7"N, 22°53'32.6"E; WGS84) located in Biebrza National Park, Poland. The dataset covers the period 2013–2024. Fluxes were derived from high-frequency measurements processed using EddyPro 6.0 (LI-COR Biosciences) following standard eddy-covariance procedures including quality control, coordinate rotation, density corrections, and uncertainty estimation. Monthly values were calculated from hourly measurements after quality filtering and gap-filling where applicable.
