Short summary

Ammonia (NH₃) is an important air pollutant which, as a precursor of fine particulate matter, raises public health concerns. Models have difficulty predicting events of pollution associated with NH₃ since ground-based observations of this gas are still relatively sparse and difficult to implement. We present the first relatively long (2.5 years) and continuous record of hourly NH₃ concentrations in Paris to determine its temporal variabilities at different scales to unravel emission sources.
