Abstract
Using the incomplete adjoint operator method in part I of this series of papers, the total emission source S can be retrieved from the pollutant concentrations ρob obtained from the air pollution monitoring network. This paper studies the problem of retrieving anthropogenic emission sources from S. Assuming that the natural source Sn is known, and as the internal source Sc due to chemical reactions is a function of pollutant concentrations, if the chemical reaction equations are complete and the parameters are accurate, Sc can be calculated directly from ρob, and then Sa can be obtained from S. However, if the chemical reaction parameters (denoted as γ) are insufficiently accurate, both γ and Sc should be corrected. This article proposes a “double correction iterative method” to retrieve Sc and correct γ and proves that this iterative method converges.
