Abstract

Continuous measurements of ambient ozone and carbon monoxide were obtained during the 2009 and 2010 trans-Atlantic AERosols and Ocean Science Expeditions, AEROSE-V and -IV, respectively. These shipboard experiments are designed to examine the influence of outflows of Saharan dust on marine boundary layer O3 and CO concentrations and on the aerosol chemistry in the tropical North trans-Atlantic Ocean. The concentrations for the gases were obtained using an infrared gas filter for CO and a UV photometer for O3. Analyses of data for carbon monoxide and ozone from both cruises will be presented and an interpreted based upon air mass history and aerosol loading. Comparisons to satellite sensing of tropospheric pollutants will also be presented.
