This Wiki contains documentation for the Western Air Quality Study (WAQS) and the Intermountain West Data Warehouse (IWDW) Project. Additional Project information can be found on the IWDW website About page.


The WAQS conducts meteorology, emissions, and air quality modeling to facilitate air resource analyses for federal and state agencies, and to provide up-to-date modeling platforms for the air quality research community.
