DESCRIPTION;LANGUAGE=en-US:Hi Everyone\,\n\nSOCAAR is pleased to announce o
ur next seminar:\n\nWednesday\, April 6\, 2016\n\n2 – 3 PM\n200 College
Street\, WB 407\n\n\n\nBridging cloud condensation nuclei activity and vol
atility of oxidized organic aerosol\n\n\nShunsuke Nakao\nAssistant Profess
or\n\nDepartment of Chemical & Biomolecular Engineering\nClarkson Universi
ty\n\n\nAging of atmospheric organic aerosol (OA) has been studied in term
s of average molecular properties such as elemental ratios (O/C\, H/C)\, v
olatility\, and hygroscopicity. Correlations between O/C and hygroscopicit
y (or cloud condensation nuclei activity)\, represented by κorg\, are a c
omputationally efficient approach to estimate the impact of aerosol aging
on cloud formation and climate\; however\, previously reported correlation
s between these two variables are largely empirical and vary widely in the
ir slopes and extrapolations to high O/C values. I will present a theoreti
cal framework based on inferred molecular formulas (CxHyOz) to constrain t
he relationships between κorg\, O/C\, volatility\, and molecular size. I
will use the theoretical framework to analyze previously-reported data for
observed κorg of highly oxidized OA to extract additional information on
physicochemical properties of organic aerosol.\n\n\nIf you are unable to
join us for the seminar in person\, we will be broadcasting the presentati
ons live during the seminar using GoToMeeting software. Please feel free t
o join us online using a web-browser or by calling in and using the webvie
wing software. If you do decide to join us\, please remember to mute your
