Radioactive gaseous-aerosol releases from the WWR-M research reactor [PDF]

open access: yesЯдерна фізика та енергетика, 2023
The radiation impact of the WWR-M research reactor is possible due to the release of radioactive substances into the environment, which are generated during both operation and decommissioning. One of the operator's responsibilities is to take measures to

Chemical ageing and transformation of diffusivity in semi-solid multi-component organic aerosol particles [PDF]

open access: yes, 2011
Recent experimental evidence underlines the importance of reduced diffusivity in amorphous semi-solid or glassy atmospheric aerosols. This paper investigates the impact of diffusivity on the ageing of multi-component reactive organic particles ...

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

open access: yesمدیریت 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 ...

Photophoresis – a Forgotten Force ??

open access: yesKONA 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.

On the Insignificance of Photochemical Hydrocarbon Aerosols in the Atmospheres of Close-in Extrasolar Giant Planets [PDF]

open access: yes, 2004
The close-in extrasolar giant planets (CEGPs) reside in irradiated environments much more intense than that of the giant planets in our solar system. The high UV irradiance strongly influences their photochemistry and the general current view believed ...

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

open access: yesRemote 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.

Nitric acid scavenging by mineral and biomass burning aerosols [PDF]

open access: yes, 1998
The abundance of gas phase nitric acid in the upper troposphere is overestimated by global chemistry-transport models, especially during the spring and summer seasons.

Impact on solar radiation parameters in India during COVID-19 lockdown: a case study

open access: yesInternational Journal of Sustainable Energy, 2021
The current research objective is to explore changes in solar radiation variables across the Indian region during the lock-down period. Global Horizontal Irradiance (GHI), Direct Normal Irradiance (DNI) and Diffuse Horizontal Irradiance (DHI) were ...

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

open access: yesNational 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

Synoptic Situation of 28-31 October 2017 Severe Dust Storm over Iraq

open access: yesAl-Mustansiriyah Journal of Science, 2021
The phenomenon of dust storms occurs in areas that are characterized by drought, and lack of rainfalls. There are many such areas around the world, including the Middle East in general and large parts of Iraq in particular.
