Satellite observations reveal that China has been amount in these regions from 2013–2016 is 11.0 %–17.2 % leading the global greening trend in the past 2 decades. We higher that from 2001–2004. We compared the long-term assessed the impact of land cover change as well as cli- HCHO vertical columns (VC) from the satellite-based Ozone mate variability on total biogenic volatile organic compound Monitoring Instrument (OMI) with the estimation of iso- (BVOC) emission in China from 2001–2016.
