Air Quality in the Northern Colorado Front Range: FRAPPÉ and DISCOVER-AQ Campaigns

Gabi Pfister

Two large air quality studies involving four aircraft and extensive ground based measurements were conducted in the Northern Colorado Front Range in the summer of 2014: the NCAR/NSF/State of Colorado Front Range Air Pollution and Photochemistry Éxperiment (FRAPPÉ) and the 4th deployment of the NASA DISCOVER-AQ. The immensely rich data set from these campaigns is analyzed to characterize the driver of high ozone pollution in the Front Range. This is a complex task given the large variety of emission sources (urban emissions with the addition of a rapidly expanding oil and natural gas sector, industry and power generation units as well as animal feedlots), the complex topography and the influence of upwind pollution and poses a large challenge to atmospheric models. 

Detailed chemical and meteorological observations during these five weeks were collected from a range of platforms including aircraft, surface sites, mobile vans, lidars, wind profilers, ozone sondes and satellites. All these have different coverage in time and space and measure different sets of parameters. In order to fully exploit the data set, there is a need and an opportunity for statistical techniques to optimally integrate the different data sets and develop ways to efficiently and conclusively compare to model output.
