FIELDS OF EXPERIENCE:

Mr. Wilkinson is a senior engineer with Alpine Geophysics. He is also a Ph.D. candidate in the Engineering and Public Policy program at Carnegie Mellon University, as well as a Ph.D. candidate in Environmental Engineering at the Georgia Institute of Technology. Mr. Wilkinson is currently conducting research in the areas of emissions uncertainty and economic-based incentives (e.g. market trading programs) to control regional emissions. More specifically, his current, primary research project is concerned with determining the geographic extent of areas whose sources may contribute to air quality exceedances. He is also interested in elucidating the impacts that uncertainty in biogenic emissions estimates have on urban- and regional-scale emissions control strategies.

Further, he is lead emissions and air quality modeler for the Southern Appalachian Mountains Initiative (SAMI) project. The SAMI is an multiepisodic, integrated (i.e. acid deposition, ozone, and visibility/particulate matter), regional-scale air quality modeling study over the eastern United States with particular focus on the southern Appalachian Mountains. Of note, the selected episodes are seven to fifteen days in length and span the years 1990 through 1995 with future years of 2010 and 2040. In the SAMI project Mr. Wilkinson is responsible for the preparation of all aspects of the air quality model ready inputs including, but not limited to, emissions estimates (e.g. the area source spatial surrogates, the mobile source emissions estimates, biogenic emissions estimates, emissions estimates speciation, and data management of the emissions data); conversion of prognostic meteorological modeling results from RAMS and MM5 to URM-ready meteorological fields; and diagnosis of boundary and inital air quality conditions. In the SAMI study, he designed, implemented, and currently maintains the geographic information system-based (GIS) components of the emissions and air quality modeling system. As part of the GIS for the SAMI project, Mr. Wilkinson maintains coverages of population, housing, urban areas, water, political boundaries (i.e. states, counties, national boundaries, and airsheds), forests, biogenic land cover, railroads, major roadways, water ports, airports, major stationary sources of air pollution, and air quality monitoring stations. The GIS-based data are used to disaggregate county-wide estimates of emissions from minor emissions sources into sub-county areas for the purposes of air quality modeling. Mr. Wilkinson uses the GIS-based data to link and display emissions estimates, to sources, to air quality observations, to air quality model predictions.

Mr. Wilkinson has completed a study to develop the first biogenic emissions inventory for northern Mexico. The new biogenic emissions inventory was integrated with existing anthropogenic emissions in an effort to better understand transboundary air pollution along the Mexico-United States border. The biogenic emissions inventory was developed from Mexican-supplied ground-truthed agricultural and forest coverage data as well as satellite-based land use data. The data were compiled for use in BEIS2.

Mr. Wilkinson has recently helped to complete a design of an air quality and meteorological monitoring network for the Breton Island National Wildlife Refuge Class I Area which is located in the Gulf of Mexico just east of New Orleans, Louisiana. Mr. Wilkinson designed the GIS emissions, air quality, and meteorological data base management system that will be used to house these data when the Breton Island Air Monitoring Program (BAMP) field program is implemented.

Recently, Mr. Wilkinson completed a study to evaluate and improve existing ammonia emissions estimates techniques for use in the San Joaquin Valley of California. This study included a comprehensive literature review which focused on the following: methods that were used to estimate ammonia emissions; the development of a new ammonia emissions inventory for the study domain; the implementation of a pilot field study to improve upon methods to estimate ammonia emissions from dairy livestock, soils, and wastewater treatment plants; and the development of methods to estimate quantitative values of uncertainty about the ammonia emissions estimates.

Mr. Wilkinson helped to complete the technical analysis for the state implementation plan (SIP) for Pittsburgh-Beaver Valley ozone non-attainment area which is located in the Pittsburgh, PA area. The technical analysis includes the emissions modeling, air quality modeling, and attainment demonstration work needed for the SIP. He also completed work to quantify ammonia emissions and their associated uncertainties in the Central California Valley. Finally, he completed work to determine the association of airborne pollutants to increased visits of children with respiratory problems to Atlanta-area emergency rooms.

Mr. Wilkinson was involved in examining the impacts that the horizontal advection solver in three dimensional air quality models had on emissions control strategies. In that study, he was responsible for statistical analysis of the air quality modeling outputs. The statistical analyses were conducted to isolate and quantify the numerical interference due to various horizontal advection solvers that were introduced into the UAM and CIT air quality models.

Mr. Wilkinson was recently involved in the Ozone Transport and Assessment Group's (OTAG) efforts to examine regional-scale air quality in the eastern United States. He was the primary engineer tasked with preparing emissions modeling inputs (e.g. area source spatial surrogates, on-road mobile source transportation network, and GIS-based EMS-95 foundation data) for the Emissions Modeling System version 1995 (EMS-95). He also provided technical support to the OTAG participants in the application of EMS-95 to the eastern United States and southern Canada.

Mr. Wilkinson's projects in the last ten years have included work with emissions modeling efforts in the Lake Michigan Ozone Study (LMOS) and the San Joaquin Valley Air Quality Study (SJVAQS) and Atmospheric Utility Signatures, Predictions, and Experiments (AUSPEX) Model Adaptation Project (SARMAP) using EMS-95. The LMOS and SARMAP are regional-scale air quality studies that were established to determine the regional emissions control strategies necessary to bring the associated ozone (and particulate matter for the SARMAP) non-attainment areas into compliance with the National Ambient Air Quality Standards (NAAQS).

Mr. Wilkinson's areas of expertise include emissions modeling systems (design, development, execution, and evaluation), design and development of data base management systems, and design and development of engineering graphics and analysis software. Mr. Wilkinson is or has been involved in the following projects:
