Org Chart - Air Quality Planning and Science Division

This page last reviewed July 30, 2018

Mission Statement: The Air Quality Planning and Science Division assesses the extent of the State's air quality problems and the progress being made to abate them, coordinates statewide development of clean air plans, maintains the CARB's databases pertaining to air quality and emissions, and applies practical and effective tools to use these data to explain the nature of California's air pollution problems in terms that may be used to design cost-effective strategies to improve the air quality. The Division's technical work provides a framework for clean air plans and ARB's regulatory programs. This support is provided in the areas of management and interpretation of emission inventory and aerometric (air quality and meteorological) data and of air quality modeling.
