Description:
Objective:This is one of the projects conducted by the Research Consortium. The objective of this research project was to develop a state-of-the-science, three-dimensional (3D) gas-aerosol atmospheric model, which includes treatment of secondary organic aerosol formation, and apply that model to the South Coast Air Basin of California (SoCAB).
Summary/Accomplishments (Outputs/Outcomes):This project involved two independent subprojects. The first subproject was the development of a new advection algorithm. The advection equation is an important component operator in the splitting scheme that accounts for the transport of pollutants under a given wind field. Low-order numerical schemes provide poor accuracy. Higher order schemes are characterized by computational noise near regions of steep gradients. Oscillations increase in amplitude and propagate to neighboring grid points producing physically unrealistic values. The main outcome of this project is a new algorithm that is an order of magnitude faster than existing high-accuracy methods. The second subproject is the application of the 3D model to simulate the SoCAB to understand the dynamics of potential control strategies. This is an example of an atmospheric problem that can only be addressed using a computational laboratory. The question that the second project addressed was: What is the implication of controlling nitrogen oxides, volatile organic compounds, and ammonia in the formation of particulate matter (PM)? That work involved the processing, handling, and analysis of large data sets over many months of supercomputer time. As a result, we produced the first detailed PM isopleths that are of interest when considering various regulatory scenarios.
