Dataset of monthly mean and annual carbon budget at Takayama in a cool-temperate deciduous forest in central Japan from 1994 to 2021

<p>This dataset contains monthly mean and annual net ecosystem production (NEP), gross primary production (GPP) and ecosystem respiration (Rec) estimated from the carbon dioxide (CO₂) flux measurement at Takayama (36&deg;09&rsquo;N, 137&deg;25&rsquo;E, 1420 m a.s.l.) in a cool-temperate deciduous forest in central Japan from 1994 to 2021. The CO₂ flux measurements were initially obtained by aerodynamic method beginning in September 1993, replaced by eddy covariance method in July 1998. This dataset was used in the manuscript &ldquo;Interannual variation and trend of carbon budget observed over a 28-year period at Takayama in a cool-temperate deciduous forest in central Japan&rdquo;, to be submitted to a scientific journal for publication.</p>
