FRAPPE: Front Range Air Pollution and Photochemistry Experiment


FRAPPE is looking at the air quality in the Northern Front Range Metropolitan Area (NFRMA) around Denver, Colorado and has important science and societal aspects.

FRAPPE is focused on the following issues:  

  1. The factors that control NFRMA surface ozone and whether current emission controls are sufficient to reduce ozone below standard
  2. The relative contributions of local mountain-valley recirculation patterns and long-range transport to buildup of photochemical oxidants and particulates during smog episodes in the NFRMA in the summer
  3. The relative contributions of the diverse local sources of pollution to air quality degradation and photochemical oxidant formation in the NFRMA
  4. To what degree does pollution from both NFRMA sources and long-range transport contribute to photochemical smog / ozone pollution, visibility degradation, and nitrate deposition in Rocky Mountain National Park and other Wilderness Regions to the West of NFRMA; and
  5. What is the impact of ozone precursor emissions from oil and gas exploration on the photochemical regime and the ozone production efficiency.
