The oxygen concentration data in a forest canopy in 2020 in Beijing Gongqing Forestry Farm

Background: With the outbreak of global climate problems in recent years, more and more countries have proposed carbon neutral plans. The measurement of forest carbon sinks is gradually becoming a research hotspot in the field of carbon sinks. Methods: : Based on observations of the amount of change in oxygen concentration in the forest canopy, we propose a simple and accurate method of forest carbon sinks measurement. Conclusions: : In this data note, we provide the data of oxygen concentration in the canopy of a 160-hectare forest in Beijing, and give a convenient equation for calculating the carbon sequestration and carbon sink according to the changes of 15 days oxygen concentration.
