ROLE OF MODELS IN AIR QUALITY MANAGEMENT DECISIONS
RAO, S.T., A. CIMORELLI, J. MOONEY, T. MACDONALD, AND A. VENKATRAM. ROLE OF MODELS IN AIR QUALITY MANAGEMENT DECISIONS. Presented at US India Workshop on Air Quality Management Decisions, Pune, INDIA, March 14 - 17, 2005.
The objective of this task is to thoroughly characterize the performance of the emissions, meteorological and chemical/transport modeling components of the Models-3 system, with an emphasis on the chemical/transport model, CMAQ. Emissions-based models are composed of highly complex scientific hypotheses concerning natural processes that can be evaluated through comparison with observations, but not truly validated. Static and Dynamic Operational, Diagnostic, and ultimately Probablistic evaluation methods are needed to both establish credibility and build confidence within the client and scientific community in the simulations results for policy and scientific applications. The characterization of the performance of Models-3/CMAQ is also a tool for the model developers to identify aspects of the modeling system that require further improvement.
Within the frame of the US-India bilateral agreement on environmental cooperation, a team of US scientists have been helping India in designing emission control policies to address urban air quality problems. This presentation discusses how air quality models need to be used for making emission management decisions.
