Heterogeneous uptake of gaseous hydrogen peroxide by Gobi and Saharan dust aerosols: a potential missing sink for H2O2 in the troposphere
gaseous hydrogen peroxide Gobi and Saharan dust aerosols H2O2 the troposphere
2010/8/16
The first direct laboratory measurements of gaseous hydrogen peroxide uptake by authentic Gobi and Saharan dust aerosol particles as a function of relative humidity (RH) have been carried out in an en...
Saharan dust transport and deposition towards the tropical northern Atlantic
Saharan dust transport tropical northern Atlantic
2009/3/13
We present a study of Saharan dust export towards the tropical North Atlantic using the regional dust emission, transport and deposition model LM-MUSCAT. Horizontal and vertical distribution of dust o...
Vertical profiles, optical and microphysical properties of Saharan dust layers determined by a ship-borne lidar
Vertical profiles Saharan dust layers ship-borne lidar
2009/3/11
A unique data set of ship-borne lidar measurements of Saharan dust layers above the Atlantic ocean has been collected aboard the research vessel Polarstern with a mobile Aerosol Raman Lidar (MARL) dur...
Ozone decomposition on Saharan dust: an experimental investigation
Ozone decomposition Saharan dust experimental investigation
2009/3/10
The heterogeneous reaction between O3 and authentic Saharan dust surfaces was investigated in a Knudsen reactor at approx 296 K. O3 was destroyed on the dust surface and O2 was formed with conversion ...
Saharan dust events at the Jungfraujoch: detection by wavelength dependence of the single scattering albedo and first climatology analysis
Saharan dust events Jungfraujoch single scattering albedo climatology analysis
2009/3/10
Scattering and absorption coefficients have been measured continuously at several wavelengths since March 2001 at the high altitude site Jungfraujoch (3580ma.s.l.). From these data, the wavelength dep...
The vertical distribution of aerosols, Saharan dust and cirrus clouds in Rome (Italy) in the year 2001
aerosols Saharan dust cirrus clouds Rome
2009/2/23
A set of 813 lidar profiles of tropospheric aerosol and cirrus clouds extinction and depolarization observed in Rome, Italy, between February 2001 and February 2002 is analyzed and discussed. The year...
The uptake of SO2 onto Saharan mineral dust from the Cape Verde Islands was investigated using a coated wall flow tube coupled to a mass spectrometer. The rate of loss of SO2 to the dust coating was ...
Observations and model calculations of trace gas scavenging in a dense Saharan dust plume during MINATROC

2009/2/12
An intensive field measurement campaign was performed in July/August 2002 at the Global Atmospheric Watch station Izaña on Tenerife to study the interaction of mineral dust aerosol and troposph...
The transport history of two Saharan dust events archived in an Alpine ice core
transport history Saharan dust event Alpine ice core
2009/1/4
Mineral dust from the Saharan desert can be transported across the Mediterranean towards the Alpine region several times a year. When coinciding with snowfall, the dust can be deposited on Alpine glac...
