[ Update this Record ]

Summary
Abstract: Our US NSF-funded project had two major parts: (1) measuring the quantum yields
for photolysis of nitrite (NO2-), nitrous acid (HNO2), and hydrogen peroxide
(HOOH) using laboratory ices, and (2) measuring the wavelength-dependent light
absorption by soluble species in snow samples from Dome Concordia and Summit,
Greenland. The laboratory photolysis ... View entire text
