Pollution transport
Air quality is influenced by both local emissions and transported quantities. Using a combination of ground-based and satellite-based remote-sensing measurements helps disentangle local and transported sources of trace gases such as carbon monoxide. The satellite instrument 
MOPITT has long been measuring atmospheric CO, and requires validation for accurate comparisons.

Wildfire impacts
Wildfires are an important contributor to air quality, emitting large amounts of a range of trace gases and aerosols relevant for health and climate. We aim to understand the impact of emission uncertainty on resulting variability in atmospheric composition. Global modeling of atmospheric composition with variable fire emission inventories helps to determine the contributions to model uncertainty.

Climate can drive many components of pollution emissions, including influencing wildfire. Fire emissions are related to the amount, type and dryness of fuel available to burn, which is in turn are related to climate. Climate modes of the major ocean basins in the Southern Hemisphere, can be linked directly to atmospheric carbon monoxide, potentially providing predictive capability of poor air quality.
