摘要

Due to the rapid growth of electricity demand and the absence of regulations, sulfur dioxide (SO_2) emissions from coal-fired power plants in India have increased notably in the past decade. In this study, we present the first interannual comparison of SO_2 emissions and the satellite SO_2 observations from the Ozone Monitoring Instrument (OMI) for Indian coal-fired power plants during the OMI era of 2005-2012. A detailed unit-based inventory is developed for the Indian coal-fired power sector, and results show that its SO_2 emissions increased dramatically by 71 % during 2005-2012. Using the oversampling technique, yearly high-resolution OMI maps for the whole domain of India are created, and they reveal a continuous increase in SO_2 columns over India. Power plant regions with annual SO_2 emissions greater than 50 Gg year~(-1) produce statistically significant OMI signals, and a high correlation (R = 0.93) is found between SO_2 emissions and OMI-observed SO_2 burdens. Contrary to the decreasing trend of national mean SO_2 concentrations reported by the Indian Government, both the total OMI-observed SO_2 and annual average SO_2 concentrations in coal-fired power plant regions increased by ＞60% during 2005-2012, implying the air quality monitoring network needs to be optimized to reflect the true SO_2 situation in India.
