Mineral quartz concentration measurements of mixed mineral dust/urban haze pollution plumes over Korea with multiwavelength aerosol Raman-quartz lidar

Lidar Determination of Quartz Concentration in the Tropospheric Mineral Aerosols – Methodology and First Results

This paper presents a lidar method that enables the determination of quartz concentration in mineral aerosols from simultaneously measured, high-spectralresolution lidar and quartz Raman lidar signals. The method and experimental results are presented.

Use of rotational Raman measurements in multiwavelength aerosol lidar for evaluation of particle backscattering and extinction

Vibrational Raman scattering from nitrogen is commonly used in aerosol lidars for evaluation of particle backscattering (β) and extinction (α) coefficients. However, at mid-visible wavelengths, particularly in the daytime, previous measurements have possessed low signal-to-noise ratio. Also, vibrational scattering is characterized by a significant frequency shift of the Raman component, so for ...

SAWA experiment – properties of mineral dust aerosol as seen by synergic lidar and sun-photometer measurements

Aerosol Filtration Using Quartz Sand Filter

The cement industry is the major source of cement dust which contains heavy metals like nickel, cobalt, lead, chromium, arsenic and hazardous substances like dioxins and furans. Exposure to these substances can cause health problems to human, animals and vegetation. A continuous pilot scale quartz sand filter was constructed and uses to study the effect of important design parameters (temperatu...
