We have found some numerical errors in our paper “The
role of ammonia in sulfuric acid ion induced nucleation”
by I. K. Ortega et al. (Atmos. Chem. Phys., 8, 2859–
2867, 2008). We discovered that i...
Ice condensation on sulfuric acid tetrahydrate: Implications for polar stratospheric ice clouds
Ice condensation sulfuric acid tetrahydrate polar stratospheric ice clouds
2009/3/11
The mechanism of ice nucleation to form Type 2 PSCs is important for controlling the ice particle size and hence the possible dehydration in the polar winter stratosphere. This paper probes heterogene...
