Job Description and Duties
The On-Road Model Implementation Section develops emission inventory methods, models, databases, and tools to support on-road emissions assessment needs in the areas of air quality planning, transportation planning, photochemical modeling, and project level assessment. Major projects include the development and refinement of EMFAC, an on-road emissions model and inventory tool for air quality and transportation planning, and developing custom tools to estimate on-road emissions on refined spatial and temporal scales for project level assessments and photochemical modeling. The section also works to update and improve on-road activity assumptions and forecasts utilizing available vehicle and socioeconomic data while reconciling estimates with those developed by regional transportation planning agencies and measurements from the federal highway performance monitoring systems (HPMS).

Under the direction of the Section Manager, the incumbent will assist in the development and applied use of mobile source emission inventory models and emissions assessments for policy planning and regulation development. The successful applicant will be responsible for mining and analyzing available mobile source related data and scientific literature in order to craft defensible and well documented methodologies based on sound scientific principles. The position requires close interaction and teamwork with Section and Branch staff as well as other clients, which span the entire agency. Specific tasks may include developing emission inventory methods and computer programming to implement those methods; optimizing MySQL databases in the EMFAC model and subsequent emissions summary and analysis tools; designing database queries and Python code to improve and update the EMFAC model, and performing quality assurance checks on emission model inputs, calculations, and output. Often assignments will require the need to derive creative solutions to new technology and policy issues.

In addition to technical data analysis and model development, staff are routinely asked to review the work of others, and to communicate with a wide variety of internal and external clients. We expect applicants to have an ability to communicate effectively on a technical and policy level, with a wide variety of stakeholders including other ARB Divisions, government agencies, policymakers, industry, environmental organizations, and the public.
