Investigation of the evolution of atmospheric particles with integration of the stochastic particle-resolved model PartMC-MOSAIC and atmospheric measurements
… the recently-developed particle-resolved model PartMC-MOSAIC, the mixing state and other physico-chemical properties of individual aerosol particles can be tracked as the particles undergo aerosol aging processes. However, existing PartMC-MOSAIC applications have mainly been based on idealized …

Black carbon mixing state in Paris during MEGAPOLI: Connecting particle resolved observation to particle resolved modeling
… models. The particle resolved aerosol model PartMC-MOSAIC, on the other hand, is a suitable interface to connect to these observations from the modeling side. In this work, we present the first PartMC-MOSAIC case study that uses data from an aerosol time-of flight mass spectrometer (ATOFMS) …

Sub-grid process analysis of the sensitivity of black carbon aging to particle microphysical properties at emission
… we use the particle-resolved aerosol model PartMC-MOSAIC to assess the aging mechanisms of black carbon-containing particles of varied initial size. PartMC-MOSAIC explicitly tracks the mass composition of each particle and is uniquely capable of resolving changes in the particle mixing state …

Sensitivity of black carbon aging to modeling assumption in CAM-chem
… more detailed particle-resolved simulations with PartMC-MOSAIC. We carried out a 1-year simulation with the global CAMChem model, where a 4-mode modal aerosol model is used. BC aerosol is transferred from a fresh, hydrophobic mode (primary carbon mode) to an aged, hydrophilic mode (accumulation …

Particle-resolved modeling for evaluating assumptions in aerosol studies
… be made regarding aerosol size and composition. PartMC-MOSAIC, being particle-resolved, does not require such assumptions. Thereby, the model provides a useful tool to evaluate assumptions and limitations within aerosol studies. This thesis, I show two applications that highlight the potential of …

Particle-resolved aerosol modeling on the regional scale – insights into importance of capturing aerosol mixing state
… the development of the particle-resolved model PartMC-MOSAIC, it became possible to simulate the aerosol mixing state in great detail. However, previous applications of PartMC-MOSAIC have lacked spatial resolution, which only a three-dimensional chemical transport model can provide. To address …

Investigating the impacts of entrainment on nucleation scavenging of black carbon particles through particle-resolved simulations
… research, we used the particle-resolved model PartMC-MOSAIC, which has the ability to track the individual size and composition of thousands of particles through the aging processes of condensation, coagulation, and chemistry. Through PartMC-MOSAIC, an urban plume scenario was simulated and an …

Black carbon mixing state impacts on aerosol activation investigations using particle-resolved model simulations
… the recently-developed particle-resolved model PartMC-MOSAIC, the mixing state and other physico-chemical properties of individual aerosol particles can be tracked as the particles undergo aerosol aging processes. As part of this dissertation this model framework was extended, and a …

Improving model representations of black carbon using a particle-resolved aerosol model
… just a few independent variables. Second, I used PartMC-MOSAIC as a benchmark for comparing other aerosol modeling frameworks. I found that cloud condensation nuclei activity can often be modeled with high accuracy using very simple representations of aerosol composition, but more complex …
