Techniques for measuring atmospheric aerosols at the High Resolution Fly's Eye experiment

open access: yes, 2005
We describe several techniques developed by the High Resolution Fly's Eye experiment for measuring aerosol vertical optical depth, aerosol horizontal attenuation length, and aerosol phase function.

Retrieval of the optical properties of tropospheric aerosols over Athens, Greece combining a 6-wavelength Raman-lidar and the CALIPSO VIS-NIR lidar system: Case-study analysis of a Saharan dust intrusion over the Eastern Mediterranean [PDF]

open access: yes, 2007
The National Technical University of Athens (NTUA) 6-wavelength (355, 387, 407, 532, 607 and 1064 nm) Raman lidar system has been used to derive the aerosol optical properties (e.g. the lidar ratio, the aerosol backscatter and extinction profile) and the

Determination of car on-road black carbon and particle number emission factors and comparison between mobile and stationary measurements [PDF]

open access: yesAtmospheric Measurement Techniques, 2015
We have used two methods for measuring emission factors (EFs) in real driving conditions on five cars in a controlled environment: the stationary method, where the investigated vehicle drives by the stationary measurement platform and the composition of ...

Inverse Methods: a Powerful Tool for Evaluating Aerosol Data, Exemplified on Cases With Relevance for the Atmosphere and the Aerosol Climate Effect [PDF]

open access: yes, 2006
For a complete description of a given aerosol, more than one parameter is necessary, e.g. parameters concerning size distribution, chemical composition, and particle morphology.

Dust-wind interactions can intensify aerosol pollution over eastern China. [PDF]

open access: yes, 2017
Eastern China has experienced severe and persistent winter haze episodes in recent years due to intensification of aerosol pollution. In addition to anthropogenic emissions, the winter aerosol pollution over eastern China is associated with unusual ...

Real-world emissions of nanoparticles, particulate mass and black carbon from a plug-in hybrid vehicle compared to conventional gasoline vehicles

open access: yesEnvironmental Advances
Among various Hybrid Electric Vehicles (HEVs), Plug-in Hybrid Electric Vehicles (PHEVs) charged from the grid are seen as the most advanced ones, as they can drive dozens of kilometers using only the electric engine and thus producing less tailpipe ...

Long-range Transport of Air Pollutants to Taiwan during the COVID-19 Lockdown in Hubei Province

open access: yesAerosol and Air Quality Research, 2020
Lockdown implemented to limit transmission of the COVID-19 virus in China reduced the emissions of air pollutants especially around Hubei Province, though restrictions were more widely applied across the country.

In situ characterization of mixed phase clouds using the Small Ice Detector and the Particle Phase Discriminator [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
Mixed phase clouds (MPCs) represent a great source of uncertainty for both climate predictions and weather forecasts. In particular, there is still a lack of understanding on how ice forms in these clouds.

Thermoluminescent aerosol analysis [PDF]

open access: yes, 1977
A method for detecting and measuring trace amounts of aerosols when reacted with ozone in a gaseous environment was examined. A sample aerosol was exposed to a fixed ozone concentration for a fixed period of time, and a fluorescer was added to the ...
