Bromine measurements in ozone depleted air over the Arctic Ocean
Bromine measurements ozone depleted air the Arctic Ocean
2010/8/16
In situ measurements of ozone, photochemically active bromine compounds, and other trace gases over the Arctic Ocean in April 2008 are used to examine the chemistry and geographical extent of ozone de...
Relationship between wind speed and aerosol optical depth over remote ocean
wind speed aerosol optical depth remote ocean
2010/8/13
The effect of wind speed on aerosol optical depth (AOD) at 0.55 μm over remote ocean regions is investigated. Remote ocean regions are defined by the combination of AOD from satellite observation and ...
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...
Quantifying the clear-sky temperature inversion frequency and strength over the Arctic Ocean during summer and winter seasons from AIRS profiles
the clear-sky temperature inversion frequency and strength the Arctic Ocean summer and winter seasons AIRS profiles
2010/8/13
Temperature inversions are one of the dominant features of the Arctic atmosphere and play a crucial role in various processes by controlling the transfer of mass and moisture fluxes through the lower ...
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...
Validation of the GRAPE single view aerosol retrieval for ATSR-2 and insights into the long term global AOD trend over the ocean
the GRAPE single ATSR-2 the long term global AOD the ocean
2010/8/13
The Global Retrieval of ATSR Cloud Parameters and Evaluation (GRAPE) project has produced a global data-set of cloud and aerosol properties from the Along Track Scanning Radiometer-2 (ATSR-2) instrume...
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...
Subseasonal variability of low cloud radiative properties over the southeast Pacific Ocean
low cloud radiative properties the southeast Pacific Ocean
2010/8/12
Subseasonal variability of cloud radiative properties in the persistent southeast Pacific stratocumulus deck is investigated using MODIS satellite observations and NCEP reanalysis data. A once-daily a...
Volcanic ash as fertiliser for the surface ocean
Volcanic ash fertiliser the surface ocean
2010/8/12
Iron is a key limiting micro-nutrient for marine primary productivity. It can be supplied to the ocean by atmospheric dust deposition. Volcanic ash deposition into the ocean represents another externa...
Winter- and summertime continental influences on tropospheric O3 and CO observed by TES over the western North Atlantic Ocean
Winter- and summertime continental influences tropospheric O3 and CO TES the western North Atlantic Ocean
2010/8/12
The distributions of tropospheric ozone (O3) and carbon monoxide (CO), and the synoptic factors regulating these distributions over the western North Atlantic Ocean during winter and summer were inves...
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...

Glacial-interglacial atmospheric CO2 change：a possible “standing volume” effect on deep-ocean carbon sequestration
Glacial-interglacial deep-ocean carbon atmospheric CO2 change
2009/12/3
So far, the exploration of possible mechanisms for glacial atmospheric CO2 drawdown and marine carbon sequestration has tended to focus on dynamic or kinetic processes (i.e. variable mixing-, equilibr...
