Fourier transform infrared time series of tropospheric HCN in eastern China: seasonality interannual variability, and source attribution
peer reviewed We analyzed seasonality and interannual variability of tropospheric hydrogen cyanide (HCN) columns in densely populated eastern China for the first time. The results were derived from solar absorption spectra recorded with a ground-based high-spectral-resolution Fourier transform infra...
