PREFACE

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

The following staff made contributions to the production of this almanac: Jeff Austin, Edith Chang, Martin Johnson, Norma Montez, Michael Redgrave, Carolyn Suer, and Jeff Wright.

This project was managed by Robert Fletcher, Chief of the Planning and Technical Support Division, Dr. Linda Murchison, Assistant Division Chief of the Planning and Technical Support Division, Debora Popejoy, Manager of the Air Quality Analysis Section, Dennis Goodenow, Manager of the Emission Inventory Systems Section, Dale Shimp, Manager of the Emission Inventory Analysis Section, and Richard Bode, Manager of the Emission Inventory Methods Section.

This is the second edition of this almanac. It will be 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 Marcella Nystrom at (916) 323-8543 or mnystrom@arb.ca.gov. For issues related to emission inventory, contact Andy Alexis at (916) 323-1085 or aalexis@arb.ca.gov.
