Preface and Table of Contents
This almanac was prepared and published by the California Air Resources Board (CARB) staff to aid air quality professionals and the public in evaluating air quality in California (State). The CARB, 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 Air Quality Planning and Science Division contributed to the production of this almanac: Jagjeet Arce, Stephen Francis, Martin Johnson, Vivian Lerch, LinYing Li, Elizabeth Melgoza, Chris Nguyen, Michael Redgrave, Jon Taylor, and Xijie Zhang. The project was approved by Kurt Karperos, Chief of the Air Quality Planning and Science Division. The project was managed by Karen Magliano, Assistant Division Chief, Carla Takemoto, Chief of the Area Source & Emission Inventory Programs Branch, Sylvia Vanderspek, Chief of the Air Quality Planning Branch, Stephen Zelinka, Manager of the Emission Inventory Development Section, Mena Shah, Manager of the Air Quality & Statistical Studies Section, and Gayle Sweigert, Manager of the Air Quality Analysis Section.
This is the eleventh edition of this almanac which has been 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 Andrews at (916) 327-7609. For issues related to emissions data, contact the Emission Inventory Branch at (916) 323-8461.
