Aircraft observations of enhancement and depletion of black carbon mass in the springtime Arctic
Aircraft observations black carbon mass the springtime Arctic
2010/10/21
Understanding the processes controlling black carbon (BC) in the Arctic is crucial for evaluating the impact of anthropogenic and natural sources of BC on Arctic climate. Vertical profiles of BC mass ...
Enhancement of the aerosol direct radiative effect by semi-volatile aerosol components: airborne measurements in North-Western Europe
the aerosol direct radiative effect semi-volatile aerosol components airborne measurements North-Western Europe
2010/9/14
A case study of atmospheric aerosol measurements exploring the impact of the vertical distribution of aerosol chemical composition upon the radiative budget in North-Western Europe is presented. Sub-m...
Studying an effect of salt powder seeding used for precipitation enhancement from convective clouds
salt powder seeding precipitation enhancement convective clouds
2010/9/1
Experimental and theoretical studies of cloud microstructure modification with hygroscopic particles for obtaining additional precipitation amounts from convective clouds are performed. The experiment...
Impact of brown and clear carbon on light absorption enhancement, single scatter albedo and absorption wavelength dependence of black carbon
brown and clear carbon light absorption enhancement single scatter albedo black carbon
2010/8/12
The presence of clear coatings on atmospheric black carbon (BC) particles is known to enhance the magnitude of light absorption by the BC cores. Based on calculations using core/shell Mie theory, we d...
Enhancement of marine cloud albedo via controlled sea spray injections: a global model study of the influence of emission rates, microphysics and transport
marine cloud albedo emission rates microphysics transport
2010/8/12
Modification of cloud albedo by controlled emission of sea spray particles into the atmosphere has been suggested as a possible geoengineering option to slow global warming. Previous global studies ha...
Measured and predicted aerosol light scattering enhancement factors at the high alpine site Jungfraujoch
aerosol light enhancement factors high alpine site Jungfraujoch
2010/3/16
Ambient relative humidity (RH) determines the water content of atmospheric aerosol particles and thus has an important influence on the amount of visible light scattered by particles. The RH dependenc...
Water-side turbulence enhancement of ozone deposition to the ocean
Water-side turbulence ozone deposition ocean
2008/11/28
A parameterization for the deposition velocity of an ocean-reactive atmospheric gas (such as ozone) is developed. The parameterization is based on integration of the turbulent-molecular transport equa...
In this paper we present evidence of enhanced N2O concentrations in the upper stratosphere/lower mesosphere polar regions after the solar proton events that occurred during October–November 2003. The ...
