Aerosol Physicochemical Mixing State and Cloud Nucleation Potential during Tracking Aerosol Convection Interactions Experiment (TRACER) Campaign.

Aerosol-cloud interactions remain a major source of uncertainty in estimating global radiative forcing due to the complex nature of the aerosol physicochemical properties. This study investigates the physicochemical characteristics of aerosols collected during the DOE's TRacking Aerosol Convection interactions Experiment (TRACER) campaign, conducted from June to September 2022 in the Greater Houston area. Aerosols were sampled at coastal (Galveston) and inland (Hempstead and Jersey Village) sites during sea-breeze initiated convection and outflow events and analyzed using Raman microspectroscopy.
