%X This dataset is constructed based on the FLUXNET2015 data framework, with extraction and compilation of monthly aggregated data from flux tower sites in the Arctic region. FLUXNET2015 is a standardized global flux network data product that integrates eddy covariance flux observations from various regional flux networks under consistent quality control. It includes measurements of material and energy exchanges such as CO₂, latent heat, and sensible heat, along with auxiliary meteorological variables. These data undergo unified processing workflows to generate products at multiple temporal resolutions (e.g., daily, weekly, monthly, and annual). In the original FLUXNET2015 processing, monthly (MM) aggregated data are derived from half-hourly or hourly data through gap-filling and QA/QC procedures. These monthly data include quality-controlled flux and driver variables, along with corresponding uncertainty estimates and quality flags.This dataset specifically selects monthly aggregated products from flux observation sites within Arctic ecosystems (sites located inside the Arctic Circle). It includes key flux variables and their associated environmental factors, adhering to the FLUXNET2015 standard variable naming conventions and quality control protocols. All site-specific monthly data are provided in a uniform format to facilitate comparative analysis and spatiotemporal synthesis across different sites.
