AREA SULPHUR DIOXIDE EMISSIONS OVER CHINA EXTRACTED FROM GOME2/METOPA OBSERVATIONS

摘要

As part of EU FP7 Monitoring and Assessment of Regional air quality in China using space Observations, Project Of Long-term sino-european co-Operation, MarcoPolo, project, the long trends of atmospheric sulphur dioxide, SO2, have been studied from a spade of satellite instruments and algorithms [Koukouli et al., 2016]. Point sources with negative trends have been identified, pointing to the implementation of air quality technologies, as well as locations with positive trends, pointing to the Chinese economy and industry increasing need for energy.Using mathematical tools, as well as apriori SO2 emission fields used in a renowned regional chemistry transport model, we investigate the possibility of improving the current emission fields by calculating a top-down emission inventory for China based on GOME2/MetopA SO2 measurements.
