Prediction of secondary organic aerosol from the multiphase reaction of gasoline vapor by using volatility-reactivity base lumping

Sanghee Han et al.

Summary: This study used the UNIPAR model to simulate the formation of secondary organic aerosol (SOA) from gasoline fuel and evaluated the model using experimental data. The results showed that gasoline SOA formation is mainly driven by aerosol-phase reactions and is sensitive to seed conditions, with a positive correlation with humidity and aerosol acidity. There is also a significant difference in SOA formation potential between arid and humid regions. Additionally, aqueous reactions and temperature have an impact on the formation of gasoline SOA.

Prediction of Phase State of Secondary Organic Aerosol Internally Mixed with Aqueous Inorganic Salts

Zechen Yu et al.

Summary: This study developed a regression model to predict aerosol phase separation relative humidity for various organic and inorganic mixes, showing that organic compounds with lower oxygen to carbon ratios, higher molecular weights, and higher aerosol acidity have greater phase separation relative humidity. Conversely, a larger fraction of inorganic nitrate led to lower phase separation relative humidity. The resulting model was demonstrated for three different SOA systems, showing liquid-liquid phase separation at relative humidity below 80%.

Simulation of Monoterpene SOA Formation by Multiphase Reactions Using Explicit Mechanisms

Zechen Yu et al.

Summary: The study simulated the formation of terpene secondary organic aerosol using a unified partitioning aerosol phase reaction model. By predicting oxygenated products and classifying them into groups based on volatility and reactivity, the model revealed three formation pathways including partitioning, oligomerization, and aqueous phase reactions. The model also included a peroxy radical autoxidation mechanism to form less volatile products.

James H. Crawford et al.

Summary: The KORUS-AQ field study conducted in 2016 provided a multi-perspective view of air quality conditions in South Korea through the use of aircraft, ground-based networks, and ships, along with air quality forecast models. The study also served as a test bed for future air quality observing strategies involving geostationary satellite instruments.

Chemical transport models often underestimate inorganic aerosol acidity in remote regions of the atmosphere

Benjamin A. Nault et al.

Summary: Observations show that the acidity of inorganic aerosols in remote areas is often higher than predicted by chemical transport models, leading to a potential underestimation of direct radiative cooling effects. Aerosol pH and ammonium balance increase with remoteness, and these differences between observations and predictions may result in underestimating direct radiative cooling effects for sulfate, nitrate, and ammonium aerosols.

Multi-model intercomparisons of air quality simulations for the KORUS-AQ campaign

Rokjin J. Park et al.

Summary: The KORUS-AQ study conducted in 2016 aimed to understand air quality factors in South Korea through extensive aircraft and ground observations. Models evaluating against these observations showed successful reproduction of certain pollutants, but systematic biases for carbon monoxide. Stratospheric ozone influxes and missing carbon monoxide sources in East Asia were identified as contributing factors to model-observation discrepancies. Ongoing model development and evaluation, along with emissions inventory improvements, are necessary for better air quality forecasting.

Influence of biomass burning vapor wall loss correction on modeling organic aerosols in Europe by CAMx v6.50

Jianhui Jiang et al.

Summary: Experimental studies suggest that vapor wall loss may lead to the underestimation of organic aerosol (OA), thus a model with vapor wall loss correction was developed for more accurate OA simulations. The optimized parameterizations were applied in a regional air quality model, showing that the VBS scheme with vapor wall loss correction performs the best in predicting OA in Europe during winter.
