Short summary

Measurements of the gas sulfur dioxide (SO₂) were made in a forest downwind of oil sands mining and production facilities in northern Alberta. These measurements tell us the rate at which SO₂ is absorbed by the forest. The measured rate is much higher than what is currently used by air quality models, which is supported by a previous study in this region. This suggests that SO₂ may have a much shorter lifetime in the atmosphere at this location than currently predicted by models.
