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.
Recent SALTRACE publications
Chouza et al. (2015): Retrieval of aerosol backscatter and extinction from airborne coherent Doppler wind lidar measurements
While aerosol lidars provide observation of aerosol layers and their optical properties, Doppler wind lidars allow the measurement of horizontal and vertical wind profiles. For aerosol transport studies, the simultaneous retrieval of aerosol and wind information is of great interest. Therefore, we developed and validated a calibration method that allows the simultaneous retrieval of aerosol optical properties and wind information from Wind lidar measurements.
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.
