Development of a Chemical Kinetic Mechanism for the U.S. EPA (Environmental Protection Agency) Regional Oxidant Model

摘要

A new generalized mechanism for use in EPA's Regional Oxidant Model has been developed. The mechanism is based on the carbon-bond concept in which organics are grouped according to the type of carbon bonding that is found in the various classes of organics. The mechanism treats biogenic as well as anthropogenic hydrocarbons. The mechanism was tested against multi-day chamber data collected by the University of California, Riverside and against isoprene/NOx data obtained in the outdoor chamber facility of the University of North Carolina. In addition to a description of the mechanism, guidance is also given on how emission data should be partitioned into the various organic groupings that are used in the mechanism.
