The AeroCom evaluation and intercomparison of organic aerosol in global models

Abstract: This paper evaluates the current status of global modeling of the organic aerosol (OA) in the troposphere and analyzes the differences between models as well as between models and observations. Thirty-one global chemistry transport models (CTMs) and general circulation models (GCMs) have participated in this intercomparison, in the framework of AeroCom phase II. The simulation of OA varies greatly between models in terms of the magnitude of primary emissions, secondary OA (SOA) formation, the number of OA spec… Show more

“…Non-negligible concentrations of OA can be found over Greenland and Antarctica due to the long-range transport of organic compounds and their condensation in the particulate phase under very low temperatures. The calculated total tropospheric OA burden is 3.3 Tg, which is higher compared to the calculated tropospheric burden of ORACLE v1.0 (2 Tg; Tsimpidi et al, 2016) but is within the range of OA tropospheric burdens (0.7 to 3.8 Tg) from 31 global CTMs reported by Tsigaridis et al (2014). Figure 3a depicts the annual average simulated O : C ratio of total OA at the surface.…”

“…For our analysis, we used model results from the Aerosol Comparisons between Observations and Models (AeroCom) project, an open international initiative aimed at understanding the global aerosol and its impact on climate (Samset et al, 2014;Myhre et al, 2013;Jiao et al, 2014;Tsigaridis et al, 2014). The project combines a large number of observations and outputs from fourteen global models to test, document, and compare state-of-the-art modelling of the global aerosol.…”
