On-line Monitoring of Atmospheric Inorganic Gases and Aerosols in the Southeastern and Northwestern USA

Atmospheric aerosols exert a large but uncertain negative (cooling) radiative forcing on regional climate. The data in this application note are compared to data collected in the Paci­fic Northwest, a comparison which helps to isolate the roles of varying regional SO₂ sources, humidity, and temperature on aerosol composition and loading.
