Short summary
The Yangtze River Delta is one of the most industrialized regions in China. In situ optical isotopic measurement in Nanjing, a city located in the Delta, showed unusually high atmospheric δ13C signals in the summer (−7.44 ‰, July 2013 mean), which we attributed to the influence of cement production in the region. Flux partitioning calculations revealed that natural ecosystems in the region were a negligibly small source of atmospheric CO2.
