Hall, EricS AND J. Gilliam. Site Location Details, Air Pollution Monitoring Equipment Used, Aircraft Flight Path Information, and Deployment Configuration for the DISCOVER-AQ (Deriving Information on Surface Conditions from COlumn and VERtically Resolved Observations Relevant to Air Quality) Field Campaign in Colorado: Summer 2014. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-16/143, 2016.
Impact/Purpose:
The goal of this EPA Technical Report is to provide the details of the Denver CO, Summer 2014 DISCOVER-AQ field campaign in a single reference document to facilitate the generation of peer-reviewed, scientific journal article manuscripts that will be written about this field activity. This ensures that the important site and equipment configuration details are preserved for this research project and that journal articles written on this research effort use the same, consistent information, derived from a single baseline source.
Description:
For EPA, this Summer 2014, Denver CO, DISCOVER-AQ field research activity focused on assessing Federal Reference Methods (FRMs) and Federal Equivalent Methods (FEMs) for ozone (O3) and Nitrogen Dioxide (NO2), while comparing their operational performance to each other and to small sensors to determine how the measurement characteristics and capabilities of small sensors compare to regulatory monitoring methods. During DISCOVER-AQ, EPA provided key ground-based (in-situ and remote sensing) measurements at sites along the flight path of the project aircraft. The results of the ambient evaluations of current and potential regulatory methods for O3 and NO2 will inform current and future NAAQS reviews with respect to methods used for NAAQS compliance monitoring. The evaluation of small sensors for O3 and NO2, along with the associated ‘citizen science’ monitoring, were leveraged during the Denver DISCOVER-AQ field study. The information and data in this EPA Technical Report documents the monitoring equipment, monitoring configuration, monitoring site locations, site and equipment points-of-contact, aircraft flight path and flight plan information, etc., for the DISCOVER-AQ Denver CO (2014) field monitoring activity. This report was developed to preserve and document the key information and details associated with the 2014 DISCOVER-AQ field campaign in Denver CO.
