However, there are still challenges in accurately representing aerosol processes in regional and global simulations. In this seminar, I will discuss how accounting for humidity dependence of organic aerosol is essential for predicting liquid-particle morphology, aerosol mass concentrations, cloud condensation nuclei, and optical absorption enhancements. I will highlight experiments using the Aerosol Optical Tweezers to inform on liquid-particle morphology and phase-separation. Those experiments then feed into the Binary Activity Thermodynamics model, which accounts for co-condensation and liquid-liquid phase separation of organic species in GEOS-Chem. Lastly, I\u0026rsquo;ll cover my emerging research into the humidity dependence of aerosol absorption, which ties the previous topics to aerosol radiative transfer and global climate simulations.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"A seminar by Dr. Kyle Gorkowski, Earth and Atmospheric Sciences"}],"uid":"34458","created_gmt":"2020-08-18 14:33:16","changed_gmt":"2020-09-09 11:51:24","author":"nlawson3","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2020-09-24T12:00:00-04:00","event_time_end":"2020-09-24T13:00:00-04:00","event_time_end_last":"2020-09-24T13:00:00-04:00","gmt_time_start":"2020-09-24 16:00:00","gmt_time_end":"2020-09-24 17:00:00","gmt_time_end_last":"2020-09-24 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"638015":{"id":"638015","type":"image","title":"Kyle Gorkowski","body":null,"created":"1597759014","gmt_created":"2020-08-18 13:56:54","changed":"1597759014","gmt_changed":"2020-08-18 13:56:54","alt":"","file":{"fid":"242658","name":"K.
