This page updated April 26, 2006.

  ARB staff provided emissions modeling support to estimate winter season CO in several calendar years not previously calculated (2004, 2009, 2015).  These budgets were developed in close coordination with the South Coast Air Quality Management District and the Southern California Association of Governments.  The budgets include EMFAC 2002 data that were available at the time of budget development.  The following links provide more detailed information regarding the methodologies, model runs, and results used in the development of these budgets.
