Wow, has it been a crazy couple of days. Despite some forest fires and cold temperatures (including rain), the trek continues. We sampled at four sites today, and we are seeing ozone concentrations at much lower levels compared to a few days ago where more methane flares were present. The map below shows our updated travels and ozone concentrations at each site. Note that measurements were taken at different times throughout the day (sunlight plays a large role); therefore,the sites cannot be compared directly at this point. Four more sampling days left, and more data to follow.
