The 1999 California Almanac of Emissions and Air Quality

Preface and Table of Contents

The Preface and Table of Contents is availabe in Acrobat format (PDF - 102K)

Preface

This almanac was prepared by the staff of the Air Resources Board to aid air quality professionals 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, Vijay Bhargava, Richard Hackney, Martin Johnson, Rachel Kirlis, Anna Komorniczak, Darryl Look, Carolyn Lozo, Kirk Rosenkranz, Ann Stewart, and Yosh Yajima.

This project was managed by Gary Agid, Assistant Division Chief of the Planning and Technical Support Division, Debora Popejoy, Manager of the Air Quality Analysis Section, and Dale Shimp, Manager of the Emission Inventory Analysis Section.

This is the first 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 related to air quality data, contact Marcella Nystrom at (916) 323-8543 or mnystrom@arb.ca.gov. For issues related to emission inventory information, contact Andy Alexis at (916) 323-1085 or aalexis@arb.ca.gov.
