Ambient Air Carbon Monoxide Measurements

摘要

A new type CO monitor was applied to special ambient air measurement problems. The monitor, a gas filter correlation (GFC) instrument, was designed specifically for use in the St. Louis Regional Air Pollution Study (RAPS), but has been applied to several other measurement requirements. The monitor has an inherently fast response of less than one second and has proved useful in documenting extremely variable monitoring situations. The monitor was used in nine separate studies and typical data are presented. The most significant contribution from these studies has been the ability to document the extreme variability of carbon monoxide in urban environments.
