Contributions of natural and anthropogenic sources to ambient ammonia in the Athabasca Oil Sands and north-western Canada [PDF]

Atmospheric Chemistry and Physics, 2018
Atmospheric ammonia (NH3) is a short-lived pollutant that plays an important role in aerosol chemistry and nitrogen deposition. Dominant NH3 emissions are from agriculture and forest fires, both of which are increasing globally.

Inverse modelling of carbonyl sulfide: implementation, evaluation and implications for the global budget [PDF]

Atmospheric Chemistry and Physics, 2021
Carbonyl sulfide (COS) has the potential to be used as a climate diagnostic due to its close coupling to the biospheric uptake of CO2 and its role in the formation of stratospheric aerosol.

Constraints and biases in a tropospheric two-box model of OH [PDF]

Atmospheric Chemistry and Physics, 2019
The hydroxyl radical (OH) is the main atmospheric oxidant and the primary sink of the greenhouse gas CH4. In an attempt to constrain atmospheric levels of OH, two recent studies combined a tropospheric two-box model with hemispheric-mean observations of ...
