Contribution of Arctic seabird-colony ammonia to atmospheric particles and cloud-albedo radiative effect

The climatic impact of ammonia emissions from Arctic seabird-colony guano is poorly understood. Here, using observations and a chemical transport model, Croftet al. illustrate that guano-associated particles promote cloud-droplet formation, resulting in a pan-Arctic cooling tendency of approximately...

Description
Summary:The climatic impact of ammonia emissions from Arctic seabird-colony guano is poorly understood. Here, using observations and a chemical transport model, Croftet al. illustrate that guano-associated particles promote cloud-droplet formation, resulting in a pan-Arctic cooling tendency of approximately −0.5 W m−2.
