Analysis of the 21-years long carbon dioxide flux dataset from a Central European tall tower site
Popis výsledku v původním jazyce
Eddy-covariance based carbon flux datasets spanning decades are becoming available worldwide due to the effort of associated scientists. Tall tower based monitoring stations are relatively rare, but provide important information about the carbon balance of a larger region surrounding the tower. In this study we report and analyze the 21-year-long dataset provided by the Hungarian tall tower site, Hegyhatsal. The daily and annual cycles of net ecosystem exchange (NEE), gross primary production, and total ecosystem respiration are presented. Footprint analysis reveals that the fluxes mostly originate from the surrounding arable lands, the main source region is located within 1 km around the tower. Long-term, mean NEE was -0,467 gC m(-2) day(-1), or -170 gC(-2) year(-1), revealing that the complex region was a net carbon sink from the atmospheric perspective. Trend analysis indicates that overall, NEE decreased (i.e. became more negative, which means stronger sink) by 12 gC m(-2) year(-1), a trend that
