Abstract
Anthropogenic emissions of nitrogen oxides and sulfur dioxide in Northeast Asia are of great concern because of their impact on air quality and atmospheric chemistry on regional and intercontinental scales. Satellite remote sensing based on DOAS (Differential Optical Absorption Spectroscopy) technique has been preferred to measure atmospheric trace species and to investigate their emission characteristics on regional and global scales. Absorption spectra obtained by the satellite-born instrument, SCIAMACHY (Scanning Imaging Absorption Spectrometer for Atmospheric Chartography) have been utilized to retrieve the information of and over Northeast Asia. levels over Northeast Asia were in order of East China, Yellow Sea, South Sea and Korean Peninsula with mean vertical columns of , , , , respectively. levels were in order of East China, Yellow Sea, Korean Peninsula, and South Sea with mean vertical columns of , , , , respectively. High levels of and were observed over East China, in particular in winter by the contribution of heating fuel combustion exhausts. The and levels over East China were the highest in January with 34% and 42% higher over the annual means. Low levels of ranged over Korean peninsula, while levels were relatively high, in particular in winter. The and levels over Yellow Sea were relatively higher compared to those over Korean peninsula and South Sea, which could be mainly attributed to their transport from East China.
