Mission objective: Take measurements of the concentrations of carbon monoxide, carbon dioxide, and methane gases
Expectations: Stagnant to slightly increased levels of each gas
Hypothesis: Concentrations have increased during the course of the year ◦ Not enough time to see effects of transition◦ Effects of Fourmile Canyon, Loveland, and Grand County
fires

Purpose of Mission: The team’s interest in the quality of air and changes that were recently experienced over the past few years◦ World’s recent transition to more environmentally
sustainable resources and fuels◦ Recent forest fires in Colorado◦ Document any measured changes◦ Data retrieved from this flight will provide
standard
