Nucleation and condensation associated with biogenic\nvolatile organic compounds (BVOCs) are important aerosol formation pathways,\nyet their contribution to the upper-tropospheric aerosols remains\ninconclusive, hindering the understanding of aerosol climate effects. Here,\nwe develop new schemes describing these organic aerosol formation processes\nin the WRF-Chem model and investigate their impact on the abundance of cloud\ncondensation nuclei (CCN) in the upper troposphere (UT) over the Amazon\nBasin. We find that the new schemes significantly increase the simulated CCN\nnumber concentrations in the UT (e.g., up to \u223c\u2009400\u2009cm\u22123\nat 0.52\u2009% supersaturation) and greatly improve the agreement with the\naircraft observations. Organic condensation enhances the simulated CCN\nconcentration by 90\u2009% through promoting particle growth, while organic\nnucleation, by replenishing new particles, contributes an additional 14\u2009%.\nDeep convection determines the rate of these organic aerosol formation\nprocesses in the UT through controlling the upward transport of biogenic\nprecursors (i.e., BVOCs). This finding emphasizes the importance of the\nbiosphere\u2013atmosphere coupling in regulating upper-tropospheric aerosol\nconcentrations over the tropical forest and calls for attention to its\npotential role in anthropogenic climate change.\n <\/jats:p>","DOI":"10.5194\/acp-23-251-2023","type":"journal-article","created":{"date-parts":[[2023,1,13]],"date-time":"2023-01-13T07:02:04Z","timestamp":1673593324000},"page":"251-272","source":"Crossref","is-referenced-by-count":1,"title":["Strong particle production and condensational growth in the upper troposphere sustained by biogenic VOCs from the canopy of the Amazon Basin"],"prefix":"10.5194","volume":"23","author":[{"given":"Yunfan","family":"Liu","sequence":"first","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0003-4889-1669","authenticated-orcid":false,"given":"Hang","family":"Su","sequence":"additional","affiliation":[]},{"given":"Siwen","family":"Wang","sequence":"additional","affiliation":[]},{"given":"Chao","family":"Wei","sequence":"additional","affiliation":[]},{"given":"Wei","family":"Tao","sequence":"additional","affiliation":[]},{"given":"Mira L.","family":"P\u00f6hlker","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0001-6958-425X","authenticated-orcid":false,"given":"Christopher","family":"P\u00f6hlker","sequence":"additional","affiliation":[]},{"given":"Bruna A.","family":"Holanda","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0002-3321-6655","authenticated-orcid":false,"given":"Ovid O.","family":"Kr\u00fcger","sequence":"additional","affiliation":[]},{"ORCID":"http:\/\/orcid.org\/0000-0003-0939-271X","authenticated-orcid":false,"given":"Thorsten","family":"Hoffmann","
