Distribution of CO₂ in Western Pacific, Studied Using Isotope Data Made in Taiwan, OCO-2 Satellite Retrievals, and CarbonTracker Products.

ABSTRACT: To assess sources and processes that affect the variability of CO₂ at local to regional scales, we have analyzed the mixing ratio [CO₂] and stable isotopic compositions (δ¹³C and δ¹⁸O) of atmospheric CO₂ for three years (2014-2016) in urban and sub-urban areas in Taipei, Taiwan. The data are compared with those from some background sites, viz., Lulin, Mauna Loa, and Minamitorishima, to evaluate how local emissions affect CO₂ level regionally. [CO₂] over the urban and sub-urban stations are significantly higher than that observed at the three aforementioned remote sites mainly due to local emissions, which partly mask the seasonal cycle caused by photosynthesis and respiration. Likewise, significantly low δ^13<
