A balloon-borne gondola carrying a particle analysis system, a backscatter sonde, and pressure and temperature sensors was launched from Kiruna, Sweden, on 25 January …
Large particles containing nitric acid (HNO3) were observed in the 1999/2000 Arctic winter stratosphere. These in situ observations were made over a large altitude range (16 to 21 …
Simultaneous in situ measurements of hydrochloric acid (HCl) and chlorine monoxide (ClO) in the Arctic winter vortex showed large HCl losses, of up to 1 part per billion by volume …

Homogeneous freezing of nitric acid hydrate particles can produce a polar freezing belt in either hemisphere that can cause denitrification. Computed denitrification profiles for one …
Polar stratospheric clouds (PSCs) play a key role in stratospheric ozone depletion. Surface- catalyzed reactions on PSC particles generate chlorine compounds that photolyze readily to …
Thermodynamic data are presented for hydrates of nitric acid: HNO3⋅ H2O, HNO3⋅ 2H2O, HNO3⋅ 3H2O, and a higher hydrate. Laboratory data indicate that nucleation and …
