Description:
This report presents data on mean seasonal total suspended particulates (TSP), sulfates, nitrates and elemental concentrations collected by a 28-station, high volume sampler network operated over a 3-year priod in the Four Corners area of Arizona, New Mexico, Utah and Colorado. Estimates of data quality are made based on results of an external quality assurance audit program. TSP values generally range from 10 to 50 micrograms per cubic meter and the sulfate/nitrate concentrations are generally less than 3 micrograms per cubic meter. All the data collected in this program are available in the U.S. Environmental Protection Agency's SAROAD (Storage and Retrieval of Acrometric Data) data system.
