Sources of Nitrate and Ozone in the Marine Boundary Layer of the Tropical North Atlantic
During the period April 1989 through December 1990, °3 concentrations in the marine boundary layer at Barbados, West Indies, show a pronounced seasonal cycle. Daily averaged values in the winter and spring often fall in the range of 25-35 ppbv for periods of several days, and they seldom fall below 20 ppbv. In contrast, during the summer, values typically fall in the range of 10-20 ppbv. During...
متن کاملStable isotopes in the atmospheric marine boundary layer water vapour over the Atlantic Ocean, 2012–2015
The water vapour isotopic composition (1H216O, H218O and 1H2H16O) of the Atlantic marine boundary layer has been measured from 5 research vessels between 2012 and 2015. Using laser spectroscopy analysers, measurements have been carried out continuously on samples collected 10-20 meter above sea level. All the datasets have been carefully calibrated against the international VSMOW-SLAP scale fol...
متن کاملMarine biogenic and anthropogenic contributions to non-sea-salt sulfate in the marine boundary layer over the North Atlantic Ocean
[1] As a part of the Atmosphere/Ocean Chemistry Experiment (AEROCE), daily aerosol samples were collected in the marine boundary layer at Barbados, West Indies (13.17 N, 59.43 W), Bermuda (32.27 N, 64.87 W), and Mace Head, Ireland (53.32 N, 9.85 W), and in the free troposphere at Izaña, Tenerife, Canary Islands (28.30 N, 16.48 W; 2360 m asl). In this report, we use multiple variable regression ...
متن کاملOzone, hydroperoxides, oxides of nitrogen, and hydrocarbon budgets in the marine boundary layer over the South Atlantic
The NASA GTE TRACE A mission sampled air over the South Atlantic and western Indian Oceans. Thirteen flight legs were flown within the marine boundary layer (MBL). The MBL was typically the cleanest air sampled (e.g., CH 4 < 1680 ppb, CO < 70 ppb, C2H 6 < 400 ppt, C3H 8 < 40 ppt, NOx < 15 ppt, and midday NO < 5 ppt) but was overlain by polluted air. The photochemistry of the MBL was influenced ...
متن کاملOzone in the boundary layer air over the Arctic Ocean: measurements during the TARA transpolar
A full year of measurements of surface ozone over the Arctic Ocean far removed from land is presented (81 N– 88 N latitude). The data were obtained during the drift of the French schooner TARA between September 2006 and January 2008, while frozen in the Arctic Ocean. The data confirm that long periods of virtually total absence of ozone occur in the spring (mid March to mid June) after Polar su...
