Ship-based detection of glyoxal over the remote tropical Pacific Ocean
Ship-based detection glyoxal the remote tropical Pacific Ocean
2010/12/20
We present the first detection of glyoxal (CHOCHO) over the remote tropical Pacific Ocean in the Marine Boundary Layer (MBL). The measurements were conducted by means of the University of Colorado Shi...
Impact of biomass burning on ocean water quality in Southeast Asia through atmospheric deposition: field observations
biomass burning ocean water quality Southeast Asia atmospheric deposition field observations
2010/12/20
Atmospheric nutrients have recently gained considerable attention as a significant additional source of new nitrogen (N) and phosphorus (P) loading to the ocean. The effect of atmospheric macro nutrie...
Impact of Manaus City on the Amazon Green Ocean atmosphere: ozone production, precursor sensitivity and aerosol load
Manaus City the Amazon Green Ocean atmosphere ozone production precursor sensitivity aerosol load
2010/10/11
We used a Single Column Chemistry and Transport Model (SCM) to infer the urban pollution emission fluxes of Manaus City, implying observed mixing ratios of CO, NOx and VOC. The model can reproduce the...
Modelling the chemically aged and mixed aerosols over the eastern central Atlantic Ocean – potential impacts
the chemically aged and mixed aerosols the eastern central Atlantic Ocean
2010/8/13
Detailed information on the chemical and physical properties of aerosols is important for assessing their role in air quality and climate. This work explores the origin and fate of continental aerosol...
Circumpolar measurements of speciated mercury, ozone and carbon monoxide in the boundary layer of the Arctic Ocean
Circumpolar measurements speciated mercury ozone and carbon monoxide the boundary layer the Arctic Ocean
2010/8/13
Using the Swedish icebreaker Oden as a platform, continuous measurements of airborne mercury (gaseous elemental mercury (Hg0), divalent gaseous mercury species HgIIX2(g) (acronym RGM) and mercury atta...
Measurement and modelling of tropospheric reactive halogen species over the tropical Atlantic Ocean
tropospheric reactive halogen species the tropical Atlantic Ocean
2010/8/13
Although tropospheric reactive halogen chemistry is well studied in coastal and polar environments, the presence of halogens over the open ocean environment has not been widely reported. The impacts o...
The chemistry of OH and HO2 radicals in the boundary layer over the tropical Atlantic Ocean
OH and HO2 radicals boundary layer tropical Atlantic Ocean
2010/2/21
Fluorescence Assay by Gas Expansion (FAGE) has been used to detect ambient levels of OH and HO2 radicals at the Cape Verde Atmospheric Observatory, located in the tropical Atlantic marine boundary lay...
Technical Note: Ensuring consistent, global measurements of very short-lived halocarbon gases in the ocean and atmosphere
Ensuring consistent very short-lived halocarbon gases ocean atmosphere
2010/2/1
Very short-lived halocarbons are significant sources of reactive halogen in the marine boundary layer, and likely in the upper troposphere and lower stratosphere. Quantifying ambient concentrations in...
On the representativeness of coastal aerosol studies to open ocean studies: Mace Head – a case study
representativeness coastal aerosol Mace Head
2009/12/31
A unique opportunity arose during the MAP project to compare open ocean aerosol measurements with those undertaken at the Mace Head Global Atmosphere Watch Station, a station used for decades for aero...
Air-sea fluxes of biogenic bromine from the tropical and North Atlantic Ocean
Air-sea fluxes biogenic bromine tropical and North Atlantic Ocean
2009/3/13
Air-sea fluxes and bulk seawater and atmospheric concentrations of bromoform (CHBr3) and dibromomethane (CH2Br2) were measured during two research cruises in the northeast Atlantic (53–59° N, June–Jul...
Open ocean DMS air/sea fluxes over the eastern South Pacific Ocean
Open ocean DMS air/sea eastern South Pacific Ocean
2009/3/12
Air/sea fluxes of dimethylsulfide (DMS) were measured by eddy correlation over the Eastern South Pacific Ocean during January 2006. The cruise track extended from Manzanillo, Mexico, along 110° W, to ...
On the origin of tropospheric O3 over the Indian Ocean during the winter monsoon: African biomass burning vs. stratosphere-troposphere exchange
tropospheric O3 Indian Ocean winter monsoon African biomass stratosphere-troposphere exchange
2009/3/12
This study investigates the origin of a commonly observed feature in the O3 profiles: mid tropospheric O3 maxima (300--500 hPa) over the tropical Indian Ocean. A comparison and analysis of model simul...
