英文摘要	Past studies have suggested that ozone in the troposphere has increased globally throughout much of the 20th century due to increases in anthropogenic emissions and transport. We show, by combining satellite measurements with a chemical transport model, that during the last four decades tropospheric ozone does indeed indicate increases that are global in nature, yet still highly regional. Satellite ozone measurements from Nimbus-7 and Earth Probe Total Ozone Mapping Spectrometer (TOMS) are merged with ozone measurements from the Aura Ozone Monitoring Instrument/Microwave Limb Sounder (OMI/MLS) to determine trends in tropospheric ozone for 1979-2016. Both TOMS (1979-2005) and OMI/MLS (2005-2016) depict large increases in tropospheric ozone from the Near East to India and East Asia and further eastward over the Pacific Ocean. The 38-year merged satellite record shows total net change over this region of about C6 to C7 Dobson units (DU) (i.e., ∼ 15 %-20%of average background ozone), with the largest increase (∼ 4 DU) occurring during the 2005- 2016 Aura period. The Global Modeling Initiative (GMI) chemical transport model with time-varying emissions is used to aid in the interpretation of tropospheric ozone trends for 1980-2016. The GMI simulation for the combined record also depicts the greatest increases of C6 to C7DU over India and East Asia, very similar to the satellite measurements. In regions of significant increases in tropospheric column ozone (TCO) the trends are a factor of 2-2.5 larger for the Aura record when compared to the earlier TOMS record; for India and East Asia the trends in TCO for both GMI and satellite measurements are ∼ +3DUdecade-1 or greater during 2005-2016 compared to about C1:2 to C1:4DUdecade-1 for 1979-2005. The GMI simulation and satellite data also reveal a tropospheric ozone increases in ∼ +4 to C5DU for the 38-year record over central Africa and the tropical Atlantic Ocean. Both the GMI simulation and satellitemeasured tropospheric ozone during the latter Aura time period show increases of ∼ +3DUdecade-1 over the N Atlantic and NE Pacific. © Author(s) 2019.
