An intensive study of aerosol optical properties in Beijing urban area
aerosol optical properties Beijing urban area
2009/12/3
In order to quantify the aerosol impact on climate, a range of aerosol parameters are required. In this paper, two-year of ground-based observations of aerosol optical properties from an urban site in...
A comparison study of regional atmospheric simulations with an elastic backscattering Lidar and sunphotometry in an urban area
regional atmospheric simulations elastic backscattering Lidar sunphotometry
2009/9/23
We describe a comparison study of Aerosol Optical Thickness (AOT) from numerical simulations using a regional atmospheric model with an elastic backscattering lidar operating at 532 nm and a sunphotom...
Mass concentration and ion composition of coarse and fine particles in an urban area in Beirut: effect of calcium carbonate on the absorption of nitric and sulfuric acids and the depletion of chloride
Mass concentration effect of calcium carbonate absorption of nitric and sulfuric acids the depletion of chloride
2009/1/8
Levels of coarse (PM10-2.5) and fine (PM2.5) particles were determined between February 2004 and January 2005 in the city of Beirut, Lebanon. While low PM mass concentrations were measured in the rai...
Analysis of Visible/SWIR surface reflectance ratios for aerosol retrievals from satellite in Mexico City urban area
Visible/SWIR aerosol retrievals Mexico City urban area
2008/12/23
The surface reflectance ratio between the visible (VIS) and shortwave infrared (SWIR) radiation is an important quantity for the retrieval of the aerosol optical depth (τa) from the MODIS sensor data....
Size distributions of elemental carbon in the atmosphere of a coastal urban area in South China: characteristics, evolution processes, and implications for the mixing state
elemental carbon coastal urban area South China
2008/11/21
Elemental carbon (EC), as one of the primary light-absorbing components in the atmosphere, has a significant impact on both regional and global climate. The environmental impacts of EC are strongly de...
