Short summary
The analysis of IASI lower tropospheric ozone columns over the North China Plain for the 2008–2016 period reveals two distinct periods: one before 2013 without any significant trend, and one after 2013 with a significant negative trend (−1.2 % yr−1). Our results suggest that the negative trend could be attributed to a reduction of the stratosphere-to-troposphere transport combined with the recent reduction of regional NOx emissions.
