POOLE-KOBER, E. PAST AND PRESENT: 50 YEARS OF AIR QUALITY MODELING RESEARCH AND ITS APPLICATIONS BY THE NOAA ATMOSPHERIC SCIENCES MODELING DIVISION. Presented at Southeast Affiliate of IAMSLIC Annual Meeting, Ocean Springs, MS, May 09 - 12, 2006.
Impact/Purpose:
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.
Description:
The NOAA Atmospheric Sciences Modeling Division (ASMD) celebrated its Golden Jubilee in September 2005. The partnership between NOAA and EPA began when the Air Pollution Unit of the Public Health Service, which later became part of the EPA, requested the Weather Bureau provide it with meteorological expertise. Thus, in 1955, a special Weather Bureau air pollution unit was formed, integrated with the Public Health Service, and located in Cincinnati, Ohio, until it moved in 1969 to Raleigh, North Carolina. This paper focuses on 50 years of air quality research performed by ASMD in collaboration with the U.S. Environmental Protection Agency and predecessor agencies.
