An Overview of CEPS1.0: Version 1.0 of the Canadian Emissions Processing System for Regional-Scale Air Quality Models

摘要

Environment Canada, Canada's national environment ministry, uses a number of regional-scale air quality models for acid deposition and photochemical oxidant modelling studies and assessments. Each model requires detailed emissions input files tailored for its domain, map projection, grid discretization, time period, time step, and chemical mechanism. To meet this need, a new and flexible regional-scale emissions preprocessor, the Canadian Emissions Processing System (CEPS1.0), has recently been developed to process current Canadian and U.S. annual national inventories of criteria air pollutants and then to generate emission input files for each air quality model as required.
