ARB Air Quality and Climate Change Studies

book The Legislature created the Boardís research program in 1971 and identified it as an integral part of an effective air pollution control program. With the mandate as its foundation, the program encompasses all aspects of air pollution. The program has and continues to sponsor relevant research of the highest scientific quality that accordingly serves as the foundation for effective regulatory decisions. Below, we link to various Air Quality and climate change studies sponsored by the ARB. View also ARB's complete research program.


The study will answer important scientific questions about emissions, chemical transformations, climate processes,transport, and meteorology in California. The air quality and meteorological data collected during CalNex will improve ARB’s emission inventories of greenhouse gases, traditional air pollutants and precursors.

The Central California Air Quality Studies (CCAQS) comprise two studies, the California Regional Particulate Air Quality Study (CRPAQS) and the Central California Ozone Study (CCOS). CCAQS is a multi-year effort of meteorological and air quality monitoring, emission inventory development, data analysis, and air quality simulation modeling.

The SCOS97 - NARSTO meteorological network and most of the air quality network collected data from June 16 through October 15, 1997. During intensive operational periods, emission data and additional meteorological and air quality data were captured for five different types of multi-day ozone episodes of interest to the sponsors.

The objective of the Lake Tahoe Atmospheric Deposition Study (LTADS) was to update estimates of atmospheric deposition to Lake Tahoe. The LTADS study quantified the direct atmospheric deposition of nutrients and particulate matter that reduce the clarity of Lake Tahoe. The LTADS study also addressed the relative contribution of local and regional sources of the atmospheric inputs.


The objective of this study is to improve accuracy of emissions inventories for GHG & aerosols, characterize composition/chemistry over SoCAB and Central Valley, characterize offshore emissions of sulfur and other pollutants from shipping and natural sources, characterize upwind BCs necessary to model local ozone and aerosols, and relate airborne & satellite observations.
