Short summary
A global chemical transport model (GEOS-Chem) was employed to simulate surface ozone and its precursors at Summit, Greenland in the Arctic and compare them with 2-year in situ surface observations. The model performed well in simulating certain species (such as carbon monoxide and propane), but some significant discrepancies were identified for other species (e.g., nitrogen oxides, ethane, PAN, and ozone). We further investigated the exact causes for model–data biases.
