Continuous measurement of atmospheric CO2 and 未13C in Beijing.
未13C depleted in heating season and enriched in vegetative season.
Diurnal variation of 未13C showed two peaks in heating season.
Coal combustion was the main local CO2 source.
未13C showed significant liner relationship with air quality index (AQI).
