Monitoring of SO₂ column concentration change over China from Aura OMI data

摘要

The spatiotemporal variation in sulphur dioxide (SO₂) concentration during 2005-2008 over China was monitored from the planetary boundary layer (PBL) SO₂ column concentration retrieved from Aura ozone monitoring instrument (OMI) data, in this study. The obtained results indicate that SO₂ concentration has an imbalanced spatial distribution with the highest level in central East China. Of the 31 provinces/municipalities/autonomous regions in mainland China, 23 still exhibited a rising trend of SO₂ concentration during 2005-2008, against eight that showed a sign of decrease. The correlation coefficient between the mean SO₂ concentration during 2005-2008 and coal consumption per unit area is as high as 0.760 if Shanghai is excluded from the analysis. With the exception of Beijing, all other provinces increased their coal consumption per unit area. Therefore, there is much more work to be done to bring down SO₂ concentration.View full textDownload full textRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/01431161.2011.603380
