Radical chemistry over sunlit snow: interactions between HOx and halogen chemistry at Summit, GreenlandEditor(s): J. Dibb, J. Kaiser, J. Stutz, R. von Glasow, and J. Abbatt
More Information Overview Paper
Active radical chemistry has been observed in the air above sunlit snow surfaces. Past observations of hydroxyl radicals in Greenland showed evidence of unrecognized chemical processes leading to OH concentrations different from those predicted in constrained box models. To investigate if halogen chemistry could explain the observations of unusual hydroxyl radical levels the Greenland Halogen and Hydrogen Radical Photochemistry Experiment (GSHOX) was performed at Summit Greenland in the Summers of 2007 and 2008.
