Evolution of the ice phase in tropical altocumulus : SAMUM lidar observations over Cape Verde
(2009-09-16)
The formation of the ice phase in tropical altocumulus has been studied with multiwavelength aerosol-cloud Raman lidar, wind Doppler lidar, and radiosonde, providing information on geometrical and optical properties, cloud ...
Vertically resolved separation of dust and smoke over Cape Verde using multiwavelength Raman and polarization lidars during Saharan Mineral Dust Experiment 2008
(2009-07-08)
Multiwavelength aerosol Raman lidar in combination with polarization lidar at Praia (14.9 degrees N, 23.5 degrees W), Cape Verde, is used to separate the optical properties of desert dust and biomass burning particles as ...
Dust and smoke transport from Africa to South America : Lidar profiling over Cape Verde and the Amazon rainforest
(2009-06-02)
Quasi-simultaneous vertically resolved multiwavelength aerosol Raman lidar observations were conducted in the near field (Praia, Cape Verde, 15 degrees N, 23.5 degrees W) and in the far field (Manaus, Amazon basin, Brazil, ...
Regional dust model performance during SAMUM 2006
(2009-02-07)
Traditionally there has been a lack of intensive measurements directly over dust sources for validating the accuracy of dust models. Utilizing the valuable and unprecedented SAMUM 2006 field campaign dust dataset in North ...
Vertically resolved dust optical properties during SAMUM : Tinfou compared to Ouarzazate
(2009-02-02)
Vertical profiles of dust key optical properties are presented from measurements during the Saharan Mineral Dust Experiment (SAMUM) by Raman and depolarization lidar at two ground-based sites and by airborne high spectral ...
State of mixing, shape factor, number size distribution, and hygroscopic growth of the Saharan anthropogenic and mineral dust aerosol at Tinfou, Morocco
(2009-02-02)
The Saharan Mineral Dust Experiment (SAMUM) was conducted in May and June 2006 in Tinfou, Morocco. A H-TDMA system and a H-DMA-APS system were used to obtain hygroscopic properties of mineral dust particles at 85% RH. ...
Numerical simulations of optical properties of Saharan dust aerosols with emphasis on lidar applications
(2009-02-02)
In the framework of the Saharan Mineral Dust Experiment (SAMUM) for the first time the spectral dependence of particle linear depolarization ratios was measured by combining four lidar systems. In this paper these measurements ...
Spatial distribution and optical properties of Saharan dust observed by airborne high spectral resolution lidar during SAMUM 2006
(2009-02-02)
Airborne measurements of pure Saharan dust extinction and backscatter coefficients, the corresponding lidar ratio and the aerosol optical thickness (AOT) have been performed during the Saharan Mineral Dust Experiment 2006, ...
Solar radiative effects of a Saharan dust plume observed during SAMUM assuming spheroidal model particles
(2009-02-02)
The solar optical properties of Saharan mineral dust observed during the Saharan Mineral Dust Experiment (SAMUM) were explored based on measured size-number distributions and chemical composition. The size-resolved complex ...
Dust mobilization and transport in the northern Sahara during SAMUM 2006 - a meteorological overview
(2009-02)
The SAMUM field campaign in southern Morocco in May/June 2006 provides valuable data to study the emission, and the horizontal and vertical transports of mineral dust in the Northern Sahara. Radiosonde and lidar observations ...
