VIEWS_OL is an aerosol chemistry dataset integrated for EPA and the Regional Planning Organizations (RPOs) [http:/vista.cira.colostate.edu/views]. It provides historical data on measurements of key components of PM2.5 (e.g. organic carbon, elemental carbon, ammonium sulfate, ammonium nitrate, inorganic soil) for many urban and rural monitoring sites across the U.S. The VIEWS chemical database is arguably the most valuable data source for quantification of dust, smoke and anthropogenic haze in different parts of the country. The VIEWS dataset is used by numerous analysis tools for the identification of dust, smoke and anthropogenic haze in different parts of the country. The VIEWS chemical dataset is provided to Datafed through a collaborative arrangement with CIRA. In a separate version of the VIEWS database, the PM2.5 concentrations are accessible for all networks, including the EPA FRM network.
