Title: Cal-Mex 2010: US and Mexico collaborative project on air quality and climate change in the California-Mexico border region

Principal Investigator / Author(s): Russell, Lynn

Contractor: UC San Diego

Contract Number: 09-356

Research Program Area: Atmospheric Processes

Topic Areas: Area Sources, Field Studies, Greenhouse Gas Emissions


Although substantial progress has been made in achieving the Border 2012 goals, air quality is still a major concern throughout the California-Mexico border region. The pressures associated with industrial and population growth, the increase in the number of old vehicles, differences in governance and regulatory frameworks, and topographic and meteorological conditions present a challenging context in which to address air quality management. These same factors also present many opportunities for binational cooperation.

The Cal-Mex 2010 Campaign is the first intensive study to investigate the cross-border transport of emissions and the impacts on regional air quality. Even though the field campaign was limited in scope, this field study has generated an extensive data set that will take years to analyze and evaluate fully. Nevertheless, many interesting results are emerging and have already added to our understanding of the transport of pollutants within the San Diego-Tijuana Air Basin and have provided valuable new information about the air quality in Tijuana.
