Unprecedented atmospheric ammonia concentrations detected in the high arctic from the 2017 canadian wildfires
From 17-22 August 2017 simultaneous enhancements of ammonia (NH3), carbon monoxide(CO), hydrogen cyanide (HCN), and ethane (C2H6) were detected from ground-based solar absorptionFourier transform infrared (FTIR) spectroscopic measurements at two high-Arctic sites: Eureka (80.05◦N,86.42◦W) Nunavut, C...
