Comparing the Performance of Different Classifiers for Urban Change Detection: A Case Study in Kingston, Ontario

This study might be the first time to evaluate the effects of NO_x and SO₂ policies on acid species in precipitation in China from 2005 to 2016 on a nation scale, based on the remotely sensed data. The ratio of S to N decrease from 2005 to 2016, while the potential acidity increase from 2005 to 2011, then decrease until 2016. This study confirms that the only controlling SO₂ emissions might not be an effect way to decrease acid rain pollution, but the joint controlling SO₂ and NO₂ does.
