International audience The abundance of NH 3 can influence new particle formation rates, aerosol chemical and optical properties, as well as N-sensitive ecosystems via deposition. Sources and sinks of gas-phase ammonia (NH 3 ) are poorly constrained in the High Arctic due to a lack of field observat...
