Description

The Continuous Non-Methane Hydrocarbon (NMHC) Measurements Study was a measurement program carried out at the Centre for Atmospheric Research Experiments (CARE) at Egbert, ON. Approximately 30 C2 to C8 hydrocarbons were collected and analyzed every three hours by an automated, in-situ gas chromatograph system. Data were collected continuously since from March, 2001 to February 2011. The objectives of the study were to collect speciated hydrocarbon data for assessing clean and polluted air masses that arrive at the site to track long term trends in of NMHC mixing ratios in this quickly developing rural area to provide input for chemical transport models and other special studies carried out at the site, and to provide a long term intercomparison data set with co-located NMHC canister sampling carried out every third day by the National Air Pollution Surveillance Network (NAPS).
