Atmospheric aerosol attenuation effect on FD data analysis at the Pierre Auger Observatory [PDF]

, 2019
The atmospheric aerosol monitoring system of the Pierre Auger Observatory has been operating smoothly since 2004. Two laser facilities (Central Laser Facility, CLF and eXtreme Laser Facility, XLF) fire sets of 50 shots four times per hour during FD ...

Aerosol optical depths in a semiarid region [PDF]

Journal of Geophysical Research: Atmospheres, 1997
To monitor changes in surface conditions from space requires information on the state of the atmosphere to correct for atmospheric effects in the remotely sensed signal. The least observed and most variable atmospheric parameters are aerosols. Of particular interest are changes of surface conditions in areas where desert encroachment is of concern.

Aerosol optical depth regime over megacities of the world

Atmospheric Chemistry and Physics, 2022
Abstract. Currently, 55 % of the world's population resides in urban areas and this number is projected to increase to 70 % by 2050. Urban agglomerations with a population over 10 million, characterized as megacities, are expected to be more than 100 by 2100. Such large concentrations of population could boost creativity and economic progress, but also

Temporal Evolution and Regional Properties of Aerosol over the South China Sea

Remote Sensing, 2023
Aerosol robotic network (AERONET) data from Dongsha Island (20.699N, 116.729E) and Taiping Island (35.90N, 3.03W) over the South China Sea (SCS) from January 2018 to December 2020 were used to analyze and discuss the temporal evolution properties of ...

Estimating aerosol emissions by assimilating observed aerosol optical depth in a global aerosol model [PDF]

Atmospheric Chemistry and Physics, 2012
Abstract. This study estimates the emission fluxes of a range of aerosol species and aerosol precursor at the global scale. These fluxes are estimated by assimilating daily total and fine mode aerosol optical depth (AOD) at 550 nm from the Moderate Resolution Imaging Spectroradiometer (MODIS) into a global aerosol model of intermediate complexity ...

Contribution of natural and anthropogenic aerosols to optical properties and radiative effects over an urban location

Environmental Research Letters, 2012
A method to determine the contribution of natural and anthropogenic aerosol species to aerosol radiative forcing using surface-based, columnar and vertical profile measurements, optical properties and radiative transfer models is outlined.

Aerosol Optical Depth Over the Nepalese Cryosphere Derived From an Empirical Model

Frontiers in Earth Science, 2019
In the Himalayan region, aerosols received much attention because they affect the regional as well as local climate. Aerosol Optical Depth (AOD) observation from satellite are limited in the Himalayan region mainly due to high surface reflectance.

The invigoration of deep convective clouds over the Atlantic: aerosol effect, meteorology or retrieval artifact? [PDF]

Atmospheric Chemistry and Physics, 2010
Associations between cloud properties and aerosol loading are frequently observed in products derived from satellite measurements. These observed trends between clouds and aerosol optical depth suggest aerosol modification of cloud dynamics, yet there ...

Determining the contribution of volcanic ash and boundary layer aerosol in backscatter lidar returns: a three‐component atmosphere approach [PDF]

, 2011
A solution of the lidar equation is discussed, that permits combining backscatter and depolarization measurements to quantitatively distinguish two different aerosol types with different depolarization properties.
