AB: The NOAA Center for Atmospheric Sciences (NCAS) conducted a combined atmospheric and oceanographic experiment aboard the NOAA Ronald H. Brown ship to characterize the physico-chemical evolution of the Saharan Aerosol Layer during its long-range transport into the eastern seaboard of the United States and the Caribbean and to quantify its effects on the regional environment and climate. The NCAS Trans-Atlantic Aerosol and Oceanographic Science Expedition (AEROSE-04) departed on its 27-day voyage February 29, 2004 from Bridgetown, Barbados and concluded in San Juan, Puerto Rico on March 26, 2004. During AEROSE-04, CO and O3 concentrations were measured to study the effects of Saharan dust on the chemistry of the atmospheric environment. Tropospheric O3 and CO were measured in-situ and on a continual basis during several dust storms that occurred during the month of March. This presentation will highlight the atmospheric measurements of CO and O3 that were taken during the AEROSE-04 mission.
