Model Intercomparison Between ADMS 3.1, AERMOD AND AERMOD PRIME
A suite of tests have been built up over time to develop a model intercomparison protocol to aid the Environment Agency in assessing the regulatory implications of the release of new models or model versions. The Environment Agency has conducted a model intercomparison study of AERMOD (99211), AERMOD Prime (02091) and ADMS 3.1. The aim of this study was to inform on the regulatory implications of the use of these models. The study investigated the model calculations of plume rise, building entrainment and the plume interaction with terrain. The models were run to generate annual mean ground level concentrations and annual percentile statistics of hourly mean ground level concentrations. In addition, they were run to examine the model responses under meteorological conditions representative of neutral conditions, unstable and stable conditions.
