AB: In the summer of 2004 extensive forest fires were burning in Alaska and western Canada. The outflow of gas-phase and aerosol species was observed over the northeastern U.S. and southeastern Canada during multiple research flights of the NOAA WP-3D aircraft. Various satellite products and chemical forecasts were used to design the flight tracks prior to take off, and images from the GOES satellite at 1 km resolution were used during flights to target the plumes using near real-time information. The approach was highly successful in localizing the forest fire plumes. In-situ measurements of acetonitrile (CH$_{3}$CN) using PTR-MS (Proton Transfer Reaction Mass Spectrometry) and of individual particles containing both potassium and carbon using PALMS (Particle Analysis by Laser Mass Spectrometry) clearly distinguished the forest fire plumes from other (urban and industrial) sources of pollution. Different intercepts of the plume showed a varying degree of photochemical processing of the forest fire emissions. In addition forest fire smoke was observed close to the surface during a nighttime flight around Boston, with a clear impact on the regional air quality for a limited period.
