A new sensitivity analysis with the Comprehensive Air Quality Model Extensions (CAMx) using a traditional two-product scheme (SOAP) and newer Volatility Basis Set (VBS) algorithm for organic aerosol (OA) calculations is presented. The simulations include default versions of SOAP VBS schemes, as well parametrizations to calculate emissions volatility distributions semi- intermediate-volatile com...

The World Health Organization estimates that every year air pollution kills seven million people worldwide. As it is expected climate change will affect future quality patterns, the full understanding of links between and change, how they human health, are challenges for research. In this scope, a methodology to assess impacts on health was developed. WRF-CAMx modelling framework applied medium...

Abstract. Increasing evidence from experimental studies suggests that the losses of semi-volatile vapors to chamber walls could be responsible for underestimation organic aerosol (OA) in air quality models use parameters obtained experiments. In this study, a box model with volatility basis set (VBS) scheme was developed, and secondary (SOA) yields vapor wall loss correction were optimized by g...

We present a proof-of-concept analysis of the measurement of the health damage of ozone (O3) produced from nitrogen oxides (NOx = NO + NO2) emitted by individual large point sources in the eastern United States. We use a regional atmospheric model of the eastern United States, the Comprehensive Air Quality Model with eXtensions (CAMx), to quantify the variable impact that a fixed quantity of NO...

The deterministic approach of sensitivity analysis is applied on the solution vector of an Air Quality Model. In particular, the photochemical CAMx code is augmented with derivatives utilising the automatic differentiation software ADIFOR. The enhanced with derivatives version of the model is then adopted in a study of the effect of perturbations at the boundary conditions on the predicted ozon...

We report the results of year-long PM2.5 (particulate matter less than 2.5 µm in diameter) simulations over Northeast Asia for base year 2013 under framework Long-range Transboundary Air Pollutants (LTP) project. LTP is a tripartite project launched by China, Japan, and Korea cooperative monitoring modeling long-range transport (LRT) air pollutants. In aspect project, each country’s group emplo...

China has imposed an ultra-low emissions (ULE) standards policy regarding the emission concentrations of thermal power industry, and region Fen-Wei Plain (China), which is important area blue-sky protection, in urgent need accelerating transformation its units to conform with China’s ULE standards. Based on high-resolution industry inventory, this study used Comprehensive Air Quality Model exte...
