The Front Range Air Pollution and Photochemistry Éxperiment (FRAPPÉ)

The Northern Front Range Metropolitan Area (NFRMA) exceeds the NAAQS for ozone on a regular basis in summer. The complex meteorology and mix of sources present challenges with respect to characterizing, modeling and forecasting the transport and photochemical processes contributing to local air quality (AQ). Additionally, long-range transport of pollution into the area and the effect of NFRMA outflow on the surrounding areas are poorly characterized.  The Front Range Air Pollution and Photochemistry Éxperiment (FRAPPÉ) was aimed at characterizing those processes which control AQ in this region during the summer, particular NFRMA surface ozone.  It was a collaborative effort in July-August 2014, and included participants from CDPHE, universities, NASA, NOAA, NCAR, and the National Park Service.  NPS focused on measurements in Rocky Mountain National Park.  Measurements at this site include organic and inorganic gases and particles, ozone and meteorology.
