Recent Air Quality Research Findings

California Regional PM10/PM2.5 Air Quality Study (CRPAQS).

Central California Ozone Study (CCOS) The Central California Ozone Study (CCOS) is operating during the summer of 2000.

1995 Integrated Modeling Study (IMS95) The 1995 Integrated Monitoring Study (IMS95) was a preliminary field program designed to collect PM10 and PM2.5 data to more effectively plan the California Regional PM10/2.5 Air Quality Study. The IMS95 had three primary components: a two week fall sampling program in November 1995; a four week winter sampling program in December 1995 and early January 1996; and a two week fog sampling program in January 1996.

Final Report of the Northern Front Range Air Quality Study. This shows how to deal with primary and secondary aerosol. It contains the results of extensive dynamometer testing of gasoline and diesel vehicles, especially high emitters.

The MOHAVE final report The US EPA has made availabile the final Project MOHAVE report, which assessed the extent to which the Mohave Generating Station, located in Laughlin, Nevada, contributes to visibility impairment at Grand Canyon National Park.

The California Air Resources Board's proposed network for PM2.5 monitors. This shows an example of network design for our largest state.

Air Quality Modeling

Chemical Mass Balance Version 8 receptor model. CMB8MAN.EXE is a self-extracting files with the users manual that tells how the model works and what are in the other files. CMB832.EXE contains the software for Windows 95. The other files are test data sets.

EPA's modeling web site. This contains software for models such as UAM and ISC3.

EPA's experimental modeling web site. Contains software for models such as CALMET and CALPUFF.

Models3 home page. The new, super-duper modeling package that is supposed to do everything.

This explains EPA AP-42 emissions factors and their activity data bases. There are many references to different control technologies, including desulfurization methods.
