Table 2. Montly total gross primary production(GPP), ecosystem respiration(Re), soil respiration(Rs), aboveground respiration(Rabove, the difference between Re and Rs), and net ecosystem production(NEP) from Nov. 1st 2019 to Oct. 31st 2020 at an approximately 57-year old Korean pine plantation on the Mt. Taehwa Seoul National University Forest, Gyeonggi-do, Republic of Korea. Total amount of carbon flux during this study period and contribution of each carbon flux component to GPP are also shown below.
