ARB's Meteorology Program

This page last reviewed September 1, 2018

Welcome to the ARB's Meteorology Section web page. The Meteorology Section provides forecasting services in support of the State's agricultural and prescribed burning program. ARB meteorologists issue daily agricultural burning control notices specifying the burn/no burn status for 11 of the State's 15 air basins, and coordinate with air quality staff from the other 4 basins. The Meteorology Section also provides meteorological and climatological services to other ARB programs.

As per Title 17 Section 80110, the ARB shall specify each day of the year as a permissive burn day, or a no-burn day for each air basin or other specified area. Also, the ARB may declare a marginal burn day if meteorological conditions approach the criteria contained in Title 17. The following are the definitions from Title 17 Section 80101(n), (q) and (t): Permissive Burn Any day on which agricultural burning, including prescribed burning, is not prohibited by the state board and burning is authorized by the district consistent with these Guidelines. Marginal Burn A day when limited amounts of agricultural burning, including prescribed burning, for individual projects in specific areas for limited times is not prohibited by the state board and burning is authorized by the district consistent with these Guidelines. No Burn Any day on which agricultural burning, including prescribed burning, is prohibited by the state board or the air district in which the burning will occur.
