Source identification and budget analysis on elevated levels of formaldehyde within the ship plumes: a ship-plume photochemical/dynamic model analysis
Source identification budget analysis the ship plumes a ship-plume photochemical/dynamic model analysis
2010/12/28
Elevated levels of formaldehyde (HCHO) along the ship corridors have been observed by satellite sensors, such as ESA/ERS-2 GOME (Global Ozone Monitoring Experiment), and were also simulated by global ...
Ozone variability and halogen oxidation within the Arctic and sub-Arctic springtime boundary layer
Ozone variability halogen oxidation the Arctic and sub-Arctic springtime boundary layer
2010/11/3
The influence of halogen oxidation on the variabilities of ozone (O3) and volatile organic compounds (VOCs) within the Arctic and sub-Arctic atmospheric boundary layer was investigated using field mea...

Aerosol fluxes and dynamics a tropical rainforest South-East Asia
2010/10/11
Atmospheric aerosol measurements were conducted near Danum Valley, in the Malaysian state of Sabah, North-East Borneo, as part of the OP3 and ACES projects, in April and June/July 2008. Here, aerosol ...
A new method for deriving aerosol solar radiative forcing and its first application within MILAGRO/INTEX-B
aerosol solar radiative forcing first application MILAGRO/INTEX-B
2010/8/25
We introduce a method for deriving aerosol spectral radiative forcing along with single scattering albedo, asymmetry parameter, and surface albedo from airborne vertical profile measurements of shortw...
Vertically-resolved particle size distribution within and above the mixing layer over the Milan metropolitan area
Vertically-resolved particle size distribution the mixing layer
2010/8/12
Vertical aerosol profiles were directly measured over the city of Milan during three years (2005–2008) of field campaigns. An optical particle counter, a portable meteorological station and a miniatur...
A review of natural aerosol interactions and feedbacks within the Earth system
natural aerosol interactions Earth system
2010/2/21
The natural environment is a major source of atmospheric aerosols, including dust, secondary organic material from terrestrial biogenic emissions, carbonaceous particles from wildfires, and sulphate f...
Modelling the optical and radiative properties of freshly emitted light absorbing carbon within an atmospheric chemical transport model
freshly emitted light carbon atmospheric chemical transport model
2010/2/21
Light absorbing carbon (LAC) aerosols have a complex, fractal-like aggregate structure. Their optical and radiative properties are notoriously difficult to model, and approximate methods may introduce...
Putting the rise of the Inca Empire within a climatic and land management context
Inca Empire land management context climatic
2009/12/3
The rapid expansion of the Inca from the Cuzco area of highland Peru (ca. AD 1400–1532) produced the largest empire in the New World. Although this meteoric growth may in part be due to the adoption o...
VOC measurements within a boreal forest during spring 2005: on the occurrence of elevated monoterpene concentrations during night time intense particle concentration events
VOC measurements boreal forest monoterpene concentrations
2009/11/19
In this study we present measurements of selected trace gases and aerosols made in a boreal forest during the BACCI-QUEST IV intensive field campaign in Hyytiälä, Finland in April 2005. Spri...
Sources and transport of Δ14C in CO2 within the Mexico City Basin and vicinity
Δ14C CO2 Mexico City Basin vicinity

Radiocarbon samples taken over Mexico City and the surrounding region during the MILAGRO field campaign in March 2006 exhibited an unexpected distribution: (1) relatively few samples (23%) were below ...
Spatial and temporal UV irradiance and aerosol variability within the area of an OMI satellite pixel
UV irradiance OMI satellite pixel aerosol variability
2009/7/22
Results of an experimental campaign that took place in the greater Thessaloniki area were used to investigate temporal and spatial UV variability within an OMI satellite pixel. UV irradiance and aeros...
