The '''California Air Resources Board''', also known as ('''CARB''') is the "clean air agency" in the [[Government of California|government of California]]. CARB was formed in 1967 by combining the Bureau of Air Sanitation and the Motor Vehicle Pollution Control Board and it is a department within the  [[California Environmental Protection Agency]].<ref>[http://www.arb.ca.gov/knowzone/history.htm A brief history of the ARB]</ref>


The stated goals of CARB include attaining and maintaining healthy [[air quality]], protecting the public from exposure to toxic air contaminants and providing innovative approaches for complying with national and state [[air pollution]] control rules and regulations.
==Governance==
CARB is governed by a board made up of eleven members appointed by the state's [[governor]].<ref>[http://www.arb.ca.gov/board/about.htm Selection of CARB's Board]</ref>
Five of the members represent the regional air quality control districts:
*One from the [[South Coast Air Quality Management District]] (Greater Los Angeles Region)
*One from the San Francisco Bay Area Air Quality Management District
*One from the San Diego Air Pollution Control District
*One from the San Joaquin Valley Unified Air Pollution Control District
*One from any other air pollution control district within California
Three of the members must fit into specific categories:
*One having expertise in automotive engineering or a closely related field.
*One having expertise in science, agriculture, or law.
*One being a physician or health effects expert.
The remaining three members are public members, one of whom must have air pollution control experience or fit into one of the above three specific categories.
==CARB's Organizational Structure==
CARB has nine major Divisions:<ref>[http://www.arb.ca.gov/html/org/org.htm CARB's Divisions]</ref>
*Administrative Services Division
*Enforcement Division
*[[Air pollution dispersion terminology|Mobile Source]] Control Division
*Mobile Source Operations Division
*Monitoring and Laboratory Division
*Office of Information Services
*Planning and Technical Support Division
*Research Division
*[[Air pollution dispersion terminology|Stationary Source]] Division
===Planning and Technical Support Division===
The Planning and Technical Support Division assesses the extent of California's air quality problems and the progress being made to abate them, coordinates statewide development of clean air plans and maintains databases pertinent to air quality and emissions.  The Division's technical support work provides a basis for clean air plans and CARB's regulatory programs. This support includes management and interpretation of emission inventories, air quality data, [[Meteorology|meteorological]] data and of [[air pollution dispersion modeling]].
The Planning and Technical Support Division has five branches:<ref name=PTSD>[http://www.arb.ca.gov/html/org/orgptsd.htm Planning and Technical Support Division]</ref>
*[[Emission inventory|Emission Inventory]] Branch
*[[Atmospheric dispersion modeling|Modeling]] & [[Meteorology]] Branch
*Air Quality Data Branch
*Air Quality & [[Transportation planning|Transportation Planning]] Branch
*[[Air pollution dispersion terminology|Mobile Source]] Analysis Branch
====Atmospheric Modeling & Support Section====
The Atmospheric Modeling & Support Section is one of three sections within the Modeling & Meteorology Branch. The other two sections are the Regional Air Quality Modeling Section and the Meteorology Section.<ref name=PTSD/>
The air quality and [[Atmospheric dispersion modeling|atmospheric pollution dispersion models]]<ref>{{cite book |author=Turner, D.B. |title=Workbook of atmospheric dispersion estimates: an introduction to dispersion modeling|edition=2nd Edition|publisher=CRC Press |year=1994 |id=ISBN 1-56670-023-X}} [http://www.crcpress.com/shopping_cart/products/product_detail.asp?sku=L1023&parent_id=&pc= www.crcpress.com]</ref><ref>{{cite book|author=Beychok, Milton R.|title=[[Fundamentals of Stack Gas Dispersion]]|edition=4th Edition|publisher=author-published|year=2005|id=ISBN 0-9644588-0-2}} [http://www.air-dispersion.com www.air-dispersion.com]</ref> routinely used by this Section include a number of the models recommended by the [[United States Environmental Protection Agency|U.S. EPA]]:<ref name=CarbSoft>[http://www.arb.ca.gov/HTML/Soft.htm Software-Utilities and Modeling]</ref>
*[[AERMOD]]: Maintained by the U.S. EPA and available from their website.<ref name=SCRAM>[http://www.epa.gov/scram001/aqmindex.htm Air Quality Models]</ref>
*[[SCREEN3]] and [[T-SCREEN]] screening models: Maintained by the U.S. EPA and available from their website.<ref name=SCRAM/>
*[[ISCST3]]: Maintained by the U.S. EPA and available from their website.<ref name=SCRAM/>
The Section also uses models which were either developed by CARB or whose development was funded by CARB, such as:<ref name=CarbSoft/>
* [[CALPUFF]]: Development funded by CARB. Currently maintained by TRC Companies.<ref>[http://www.src.com/calpuff/calpuff1.htm The CALPUFF Modeling System]</ref>
* [[CALINE-4]]: Maintained by the California Department of Transportation (Caltrans) and available from their website.<ref>[http://www.dot.ca.gov/hq/env/air/pages/calinemn.htm CALINE4 Manual]</ref>
* [[CALGRID]]: Developed by CARB and currently maintained by CARB.<ref>[http://www.arb.ca.gov/eos/soft.htm#calgrid|CARB's CALGRID Model]</ref>
