Dust composition and mixing state inferred from airborne composition measurements during ACE-Asia C130 Flight #6
In this study 3.5min average bulk aerosol composition data recorded from aircraft during ACE-ASIA C130 Flight #6 are used to investigate the extent of fine particle (Dp 50 o 1.3mm) mixing among various inorganic aerosol particle constituents. Dust-laden air masses that had mixed with urban air pollutants over the Beijing and Tianjin region were subsequently recorded in the marine boundary layer...
متن کاملInfluence of relative humidity upon pollution and dust during ACE-Asia: Size distributions and implications for optical properties
[1] An extensive set of aerosol physical and optical measurements was taken over the waters east of Asia during the Aerosol Characterization Experiment-Asia (ACE-Asia) project in the spring of 2001. Dust storms upwind of the study area combined with intense pollution plumes from coastal cities yielded an opportunity to examine both types of aerosol, in isolation and as they interacted. Scatteri...
متن کاملSTUDIES with the AEROSOL MASS SPECTROMETER
Fast time-response of the Aerodyne Aerosol Mass Spectrometer (AMS) makes it a well-suited instrument for ambient field measurements. On the other hand, laboratory chamber experiments provide the opportunity to study a specific system in a more controlled environment. The goal of this thesis is to provide a summary of laboratory and field measurements using the AMS. During laboratory chamber pho...
متن کاملDerbyshire Natural Minerogenic Dust and Human Health
Atmospheric aerosols include gases and liquids, as well as solid particles. They include material derived from both oceans and landmass, as well as particles that form within the atmosphere, such as sulfates. Solid particles entrained in the atmosphere by detachment from poorly vegetated surfaces (the process of deflation) include, for example, rock and mineral dust, fine mineral aggregates, fi...
متن کاملSize-resolved source apportionment of particulate matter in urban Beijing during haze and non-haze episodes
Additional size-resolved chemical information is needed before the physicochemical characteristics and sources of airborne particles can be understood; however, this information remains unavailable in most regions of China due to lacking measurement data. In this study, we report observations of various chemical species in size-segregated particle samples that were collected over 1 year in the ...
