Long-range Transport of 2023 Canadian Wildfire Smoke into the Northeastern United States

Key Points

To examine the transport of smoke from Canadian wildfires into the northeastern United States and its impacts on air quality.
Utilized NASA's GEOS model for visualization.
Analyzed smoke transport dynamics from May 31 to July 7, 2023.
Focused on meteorological conditions driving transport.
Record-breaking poor air quality observed across the northeastern United States.
Significant smoke dispersion from Alberta and Quebec wildfires.
Visualized aerosol transport pattern during a critical impact period.

Abstract

In summer 2023, Canada experienced its most intense wildfire season on record. Smoke from wildfires in Alberta and Quebec was transported thousands of miles, driven by favorable meteorological conditions, resulting in record-breaking poor air quality across the northeastern United States. This animation, powered by NASA's GEOS model, visualizes aerosol transport from May 31 – July 7, 2023 — the period of most dramatic impact on eastern U.S. air quality.Originally published at https://svs.gsfc.nasa.gov/5631/.
