#A02 Climate sensitivity to marine organic aerosol emissions in ACME v0

Abstract

We performed sensitivity simulations (10 y) in a version of ACME v0 to test the model's climate response to emissions of marine organic matter with sea spray aerosol, under several sensitivity cases.  We will show selected results from these simulations.  We compare concentrations and composition of marine aerosol with in situ observations, and we examine the sensitivity to the new emissions of model aerosol properties, cloud distributions and properties, and climate variables (e.g., wind speed, TOA forcing).
