Chemical Speciation Network (CSN)
The CSN was established to meet the regulatory requirements for monitoring speciated PM2.5 to determine the chemical composition of these particles. The purpose of the CSN is to determine, over a period of several years, trends in concentration levels of selected ions, metals, carbon species, and organic compounds in PM2.5.The program began in 1999 with 54 Speciation Trends Network (STN) sites across the nation located primarily in or near larger Metropolitan Statistical Areas (MSAs) and has increased to 200 sites nationwide. In the database and in most of the references on the VIEWS website, this network is currently referred to as the "EPA PM2.5 Speciation - Daily" network.
