Welcome to the SALTRACE website

The SALTRACE initiative

SALTRACE, the Saharan Aerosol Long-range Transport and Aerosol-Cloud-Interaction Experiment, is a German initiative which combines ground-based and airborne in-situ and lidar measurements with meteorological data, long-term measurements, satellite remote sensing and modeling to investigate the long-range transport of Saharan mineral dust across the Atlantic Ocean into the Caribbean. SALTRACE continues the work started with the Saharan Mineral dust Experiment (SAMUM; 2004-2011) and will help to close open gaps in our understanding of mineral dust in the climate system. Many of the forthcoming publications using SALTRACE data will be collected in the AMT/ACP special issue 382.

Recent SALTRACE publications

Jähn et al. (2016): Investigations of boundary layer structure, cloud characteristics and vertical mixing of aerosols at Barbados with large eddy simulations

In a recent SALTRACE publication Jähn et al. (2016) performed large eddy simulations (LESs) for the area of the Caribbean island Barbados to investigate island effects on boundary layer modification, cloud generation and vertical mixing of aerosols. A numerical sensitivity study reveals effects of initial atmospheric state, turbulence and model grid spacing on the simulation results, e.g., a strong trade inversion suppresses vertical growth of trade wind cumuli. The analysis of incoming Saharan dust layers shows the effects of layer thinning, subsidence and turbulent downward transport. The results were sensitive to atmospheric stability and wind shear. Comparisons of LES model output and lidar data were in good agreement.

The SALTRACE field experiment

After 5 weeks of intensive measurements, the SALTRACE field experiment ended on 15 July 2013. We were very lucky with the weather and studied mineral dust from several dust outbreaks with the DLR research aircraft Falcon between Senegal and Florida. On the eastern side of the Atlantic, dust plumes extended up to about 6 km altitude, while the dust layers in the Caribbean were mainly below 4.5 km. Highlights during SALTRACE included the sampling of a dust plume in the Cape Verde area on 17 June which was again measured with the same instrumentation on 21 and 22 June near Barbados. The event was also captured by the ground-based lidar and in-situ instrumentation. Another highlight was the formation of tropical storm Chantal in the dusty environment.
