Measurements show three time periods characterized by high ozone mixing ratios (OMRs) in the troposphere on 8, 11, and 18–20 August 2013 during the Asian summer monsoon (ASM) season. Here, we verified two different sources for the enhanced ozone values in the troposphere. First, transport of polluted air from the boundary layer, and second downward transport from the stratosphere by stratospheric intrusions. Air pollution from South Asia through convective and long-range transport plays a key role in enhancing middle tropospheric OMRs up to 90 % on 8 August and up to 125 % on 11 August 2013 compared to monthly mean ozone of August 2013. Stratospheric air intruded from the northern high-latitudes to the southeastern flank of the ASM anticyclone to the troposphere and is identified as the source of enhanced ozone according to backward trajectory calculation and satellite measurements by the Ozone Monitoring Instrument (OMI) and the Atmospheric Infrared Sounder (AIRS). Air parcels with high ozone moved from the high-latitude lower stratosphere to the middle and upper troposphere. These air parcels are then transported to Lhasa over long distances and enhanced upper and middle tropospheric ozone over Lhasa during 18–20 August 2013. Our findings demonstrate that the strong variability of ozone within the ASM anticyclone in the free troposphere is caused by transport from very different regions of the atmosphere. 000858787 536__ $$0G:(DE-HGF)POF3-244$$a244 - Composition and dynamics of the upper troposphere and middle atmosphere (POF3-244)$$cPOF3-244$$fPOF III$$x0 000858787 588__ $$aDataset connected to CrossRef 000858787 7001_ $$0P:(DE-Juel1)129164$$aVogel, Bärbel$$b1$$ufzj 000858787 7001_ $$0P:(DE-Juel1)129138$$aMüller, Rolf$$b2 000858787 7001_ $$0P:(DE-HGF)0$$aBian, Jianchun$$b3 000858787 7001_ $$0P:(DE-Juel1)129123$$aGünther, Gebhard$$b4 000858787 7001_ $$0P:(DE-HGF)0$$aLi, Qian$$b5 000858787 7001_ $$0P:(DE-HGF)0$$aZhang, Jinqiang$$b6 000858787 7001_ $$0P:(DE-HGF)0$$aBai, Zhixuan$$b7 000858787 7001_ $$0P:(DE-HGF)0$$aVömel, Holger$$b8 000858787 7001_ $$0P:(DE-Juel1)129145$$aRiese, Martin$$b9$$ufzj 000858787 773__ $$0PERI:(DE-600)2069847-1$$a10.5194/acp-18-17979-2018$$gVol. 18, no. 24, p. 17979 - 17994$$n24$$p17979 - 17994$$tAtmospheric chemistry and physics$$v18$$x1680-7324$$y2018 000858787 8564_ $$uhttps://juser.fz-juelich.de/record/858787/files/invoice_Helmholtz-PUC-2019-7.pdf 000858787 8564_ $$uhttps://juser.fz-juelich.de/record/858787/files/acp-18-17979-2018.pdf$$yOpenAccess 000858787 8564_ $$uhttps://juser.fz-juelich.de/record/858787/files/acp-18-17979-2018.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000858787 8564_ $$uhttps://juser.fz-juelich.de/record/858787/files/invoice_Helmholtz-PUC-2019-7.pdf?subformat=pdfa$$xpdfa 000858787 8767_ $$8Helmholtz-PUC-2019-7$$92019-01-03$$d2019-01-07$$eAPC$$jZahlung erfolgt 000858787 909CO $$ooai:juser.fz-juelich.de:858787$$pdnbdelivery$$popenCost$$pVDB$$pVDB:Earth_Environment$$pdriver$$pOpenAPC$$popen_access$$popenaire 000858787 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)173997$$aForschungszentrum Jülich$$b0$$kFZJ 000858787 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129164$$aForschungszentrum Jülich$$b1$$kFZJ 000858787 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129138$$aForschungszentrum Jülich$$b2$$kFZJ 000858787 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129123$$aForschungszentrum Jülich$$b4$$kFZJ 000858787 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129145$$aForschungszentrum Jülich$$b9$$kFZJ 000858787 9131_ $$0G:(DE-HGF)POF3-244$$1G:(DE-HGF)POF3-240$$2G:(DE-HGF)POF3-200$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bErde und Umwelt$$lAtmosphäre und Klima$$vComposition and dynamics of the upper troposphere and middle atmosphere$$x0 000858787 9141_ $$y2018 000858787 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000858787 915__ $$0LIC:(DE-HGF)CCBY4$$2HGFVOC$$aCreative Commons Attribution CC BY 4.0 000858787 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000858787 915__ $$0StatID:(DE-HGF)9905$$2StatID$$aIF >= 5$$bATMOS CHEM PHYS : 2017 000858787 915__ $$0StatID:(DE-HGF)0501$$2StatID$$aDBCoverage$$bDOAJ Seal 000858787 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000858787 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000858787 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000858787 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000858787 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000858787 915__ $$0StatID:(DE-HGF)0030$$2StatID$$aPeer Review$$bDOAJ : Peer review 000858787 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bATMOS CHEM PHYS : 2017 000858787 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000858787 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000858787 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List 000858787 9201_ $$0I:(DE-Juel1)IEK-7-20101013$$kIEK-7$$lStratosphäre$$x0 000858787 9801_ $$aAPC 000858787 9801_ $$aFullTexts 000858787 980__ $$ajournal 000858787 980__ $$aVDB 000858787 980__ $$aI:(DE-Juel1)IEK-7-20101013 000858787 980__ $$aAPC 000858787 980__ $$aUNRESTRICTED 000858787 981__ $$aI:(DE-Juel1)ICE-4-20101013
