Abstract

This paper reviews activities over the past nine years involving the evaluation, verification and development of atmospheric transport and diffusion models applied to air pollution assessments in complex/ mountainous terrain settings. Results from experiments performed at different complex terrain settings under stably stratified flow conditions have been emphasized. Comparisons of model predictions to observations are made. Physical modeling laboratory tests simulating flow conditions for full-scale experiments complement the data bases and provide information on systematic variations of modeling parameters and input conditions for mathematical model development purposes. Principal findings from these and other experiments on specific technical issues are summarized.
