A sea-state based source function for size- and composition-resolved marine aerosol production
source function size- and composition-resolved marine aerosol production
2011/2/25
A parameterization for the size- and composition-resolved production fluxes of nascent marine aerosol was developed from prior experimental observations and extrapolated to ambient conditions based on...
An integrated modeling study on the effects of mineral dust and sea salt particles on clouds and precipitation
mineral dust sea salt particles clouds
2011/2/24
This report addresses the effects of pollution on the development of precipitation in clean ("pristine") and polluted ("hazy") environments in the Eastern Mediterranean by using the Integrated Communi...
Ozone production during the field campaign RISFEX 2003 in the sea of Japan: analysis of sensitivity and behaviour based on an improved indicator
Ozone production the field campaign RISFEX 2003 the sea of Japan an improved indicator
2010/10/21
The ratio Φ=kHC+OH[HC]/kNOx+OH[NOx] is used as an indicator for the sensitivity of ozone production (P(O3)) to HC and NOx in the field campaign RISFEX 2003 (RIShiri Fall EXperiment 2003) at Rishiri Is...
The effect of Arctic sea-ice extent on the absorbed（net）solar flux at the surface, based on ISCCP-D2 cloud data for 1983–2007
Arctic sea-ice absorbed solar flux ISCCP-D2 cloud data
2010/2/1
We estimate the effect of the Arctic sea ice on the absorbed (net) solar flux using a radiative transfer model. Ice and cloud input data to the model come from satellite observations, processed by the...
Constraining the concentration of the hydroxyl radical in a stratocumulus-topped marine boundary layer from sea-to-air eddy covariance flux measurements of dimethylsulfide
hydroxyl radical stratocumulus-topped marine boundary layer sea-to-air eddy covariance flux measurements
2009/12/31
The hydroxyl radical (OH) is an important oxidant in the troposphere due to its high reactivity and relative abundance. Measuring the concentration of OH in situ, however, is technically challenging. ...
A modelling system for the exhaust emissions of marine traffic and its application in the Baltic Sea area
modelling system exhaust emissions marine traffic Baltic Sea area
2009/12/31
A method is presented for the evaluation of the exhaust emissions of marine traffic, based on the messages provided by the Automatic Identification System (AIS), which enable the identification and lo...
Elevated nitrogen-containing particles observed in Asian dust aerosol samples collected at the marine boundary layer of the Bohai Sea and the Yellow Sea
Elevated nitrogen-containing particles Asian dust aerosol samples Bohai Sea Yellow Sea
2009/9/23
Low-Z particle electron probe X-ray microanalysis (low-Z particle EPMA) shows powerful advantages for the characterization of ambient particulate matter in environmental and geological applications. B...
What can we learn about ship emission inventories from measurements of air pollutants over the Mediterranean Sea?
ship emission inventories air pollutants Mediterranean Sea
2009/9/23
Ship emission estimates diverge widely for all chemical compounds for several reasons: use of different methodologies (bottom-up or top-down), activity data and emission factors can easily result in a...
Photoinduced oxidation of sea salt halides by aromatic ketones: a source of halogenated radicals
Photoinduced oxidation sea salt halides aromatic ketones halogenated radicals
2009/7/15
The interactions between triplet state benzophenone and halide anion species (Cl, Br and I have been studied by laser flash photolysis (at 355 nm) in aqueous solutions at room temperature. The decay o...
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...
The impact of diurnal variability in sea surface temperature on the central Atlantic air-sea CO2 flux
sea surface temperature central Atlantic air-sea CO2 flux
2009/3/12
The effect of diurnal variations in sea surface temperature (SST) on the air-sea flux of CO2 over the central Atlantic ocean and Mediterranean Sea (60 S–60 N, 60 W–45 E) is evaluated for 2005–2006. We...

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 ...
The effects of experimental uncertainty in parameterizing air-sea gas exchange using tracer experiment data
parameterizing air-sea gas tracer
2009/3/12
It is not practical to measure air-sea gas fluxes in the open ocean for all conditions and areas of interest. Therefore, in many cases fluxes are estimated from measurements of air-phase and water-pha...
