- •
Atmospheric CO2 and CH4 mole fractions at Shangdianzi regional background station located at northern China are reported.
- •
The observed records were selected into locally influenced, BTH influenced, and RMI influenced.
- •
The observed CO2 and CH4 were influenced by air masses from Northwest (RMI) or from South and Southeast (BTH).
- •
The annual growth rate of CO2 and CH4 in Beijing-Tianjin-Hebei plain are 3.8 ± 0.01 ppm yr−1 and 10 ± 0.1 ppb yr−1.
- •
The strengths of CO2 and CH4 emission in Beijing-Tianjin-Hebei plain increased more than 20% every year.
