Evaluation of the ability of radiation transmission model and MODIS images to estimate aerosol optical depth [PDF]

مدیریت بیابان, 2018
Aerosols play an important role in the climate system of the atmosphere. These atmospheric particles are directly affected by changing radiation exposure by diffusing and absorbing different wavelengths and indirectly by changing the optical properties ...

An overview of the ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) project: aerosol–cloud–radiation interactions in the southeast Atlantic basin

, 2021
. Southern Africa produces almost a third of the Earth’s biomass burning (BB) aerosol particles, yet the fate of these particles and their influence on regional and global climate is poorly understood.

Biomass burning aerosols in most climate models are too absorbing

Nature Communications, 2021
Uncertainty in the representation of biomass burning (BB) aerosol composition and optical properties in climate models contributes to a range in modeled aerosol effects on incoming solar radiation.

Photophoresis – a Forgotten Force ??

KONA Powder and Particle Journal, 2014
In general a force will act on a particle illuminated by light or other radiation and absorbing part of the flux, and as a consequence a motion will result.

Using Machine Learning Methods to Identify Particle Types from Doppler Lidar Measurements in Iceland

Remote Sensing, 2021
Doppler lidars are used worldwide for wind monitoring and recently also for the detection of aerosols. Automatic algorithms that classify the lidar signals retrieved from lidar measurements are very useful for the users.

South-hemispheric marine aerosol Hg and S isotope compositions reveal different oxidation pathways

National Science Open, 2022
Particle-bound mercury (PBM) records the oxidation of elemental mercury, of which the main oxidation pathways (Br∙/Cl∙/OH∙/O3) remain unclear, especially in the Southern Hemisphere. Here, we present latitudinal covariations of Hg and S-isotopic anomalies
