The California Almanac of Emissions and Air Quality
This page last reviewed April 5, 2012
Much of the information used to develop the Almanac is accessible through a variety of databases and tools available on the ARB website.
The following are links to some of this valuable information that lies on the ARB's website.
Real-time Air Quality Data - Air Quality and Meteorological Information System (AQMIS2) - Allows access to near real-time air quality and meteorological data. These data are available in tabular summary reports.
Historical Air Quality Data - Aerometric Data Analysis and Management System (iADAM) - Allows access to historical data (data for record) in tabular summary reports or displayed as graphs.
Emission Inventory Data - Allows access to historical and projected emissions, vehicle activity, and human population. Data is available for 2004, as well as for the years 1975-2020 at five year intervals.
Facility Search Engine - Allows users to locate criteria or toxics emissions data for a specific facility.
Top 25 Source Categories - Provides users with emissions for the top 25 highest emitting source categories by geographic area.
Community Level Emissions - Community Health Air Pollution Information System (CHAPIS) - Allows users to query and view emissions using a map interface.
Toxics Emission Factors - California Air Toxics Emission Factor database (CATEF) - Provides over 2000 emission factors to estimate toxic air emissions for specific industrial processes or emissions.
Area Designations - Provides information regarding the designation areas in California with respect to the State Ambient Air Quality Standards.
Biomass Burning Alternatives - Information on alternatives to burning and provides information on service providers in this effort.
Central California Air Quality Studies (CCAQS) - Comprises two studies with the goal of providing an improved understanding of par-ticulate matter and visibility in central California.
Climate Change - Information regarding ARB's Climate Change Program.
Goods Movement (GMP) - Presentation material and policy information on California's Goods Movement Plan.
Outdoor residential waste burning information - Provides infor-mation on regulations for outdoor residential waste burning and includes resources on alternatives to burning.
Air Quality Data Quality Assurance Site Index - Air monitoring web site that allows the user to gain access to the most recent qual-ity assurance information on any particular air monitoring site. This information consists of pollutants monitored, location, operation information, and photos of the site if available.
Transport - Information on the movement of ozone and ozone pre-cursors between basins or regions and established mitigation require-ments.
