HO2 and RO2 measurements during OASIS Barrow field intensive Spring 2009


A measurement intensive campaign was carried out in Barrow, Alaska, in spring 2009 as part of the Ocean Atmosphere Sea Ice Snowpack (OASIS) program. The central focus of this campaign was the role of halogen chemistry in the Arctic. This dataset contains HO2 and RO2 measurements.

These data were collected using a Chemical Ionization Mass Spectrometer (CIMS) based instrument. An inlet collects ambient air from the free air stream and adds reagents, including O2 or N2 diluents, and NO and SO2 reagent gases. Data were gathered from 01 March 2009 through 14 April 2009.
