PREFACE

This almanac was prepared and published by the Air Resources Board (ARB) staff to aid air quality professionals and the public in evaluating air quality in California (State). The ARB, as part of the California Environmental Protection Agency (CalEPA), is the State board responsible for achieving and maintaining healthful air quality in California. This responsibility is shared with local air districts and the United States Environmental Protection Agency (U.S. EPA).

The following staff and managers of the Planning and Technical Support Division contributed to the production of this almanac: Andy Alexis, Dr. Michael Benjamin, Vijay Bhargava, Chris Halm, Martin Johnson, Darryl Look, Elizabeth Melgoza, Sylvia Morrow, Theresa Najita, Chris Nguyen, John Nguyen, Michael Redgrave, Dale Shimp, Jon Taylor, and Xijie Zhang. The project was approved by Dr. Linda Murchison, Chief of the Planning and Technical Support Division. The project was managed by Karen Magliano, Chief of the Air Quality Data Branch, Richard Bode, Chief of the Emission Inventory Branch, Mena Shah, Manager of the Air Quality Data Section, and Gayle Sweigert, Manager of the Air Quality Analysis Section.

This is the tenth edition of this almanac which is updated annually as additional air quality and emission inventory data become available. If you find errors or have suggestions for improvements, please let us know. For general issues or issues related to air quality data, contact Paul Cox at (916) 327-7609 or pcox@arb.ca.gov. For issues related to emissions data, contact Andy Delao at (916) 324-7169 or adelao@arb.ca.gov. For issues related to air toxics data, contact Robert Weller at (916) 322-6158 or rweller@arb.ca.gov.
