Variability, origin and physical characteristics of dust aerosol in Iceland
… of the total particulate air pollution. Less industrialized and inhibited regions, such as deserts, can contribute remarkably to air pollution. Iceland is a good example of such areas. The trends in long-term dust activity in Iceland and results from the pioneer field experiments on dust …

Cloud condensation nucleus activity comparison of dry- and wet-generated mineral dust aerosol : the significance of soluble material
… illite and sodium-rich montmorillonite, and an industrially derived sample, Arizona Test Dust. Using wet and dry particle generation coupled to a differential mobility analyzer (DMA) and cloud condensation nuclei counter, the critical activation of the clay mineral particles as cloud condensation …

Modeling of Plasma Irregularities Associated with Artificially Created Dusty Plasmas in the Near-Earth Space Environment
… associated with the creation of an artificial dust layer in the earth's ionosphere is investigated. The Charged Aerosol Release Experiment (CARE) aims to understand the mechanisms for enhanced radar scatter from plasma irregularities embedded in dusty plasmas in space. Plasma irregularities …

Remote measurement of aerosol optical properties using the NOAA POES AVHRR during ACE-1, TARFOX and ACE-2
… Phase functions are parameterized using an aerosol distribution model and the ratio of radiance values measured in channels 1 and 2 of the AVHRR. Automated cloud screening and sun glint removal is included. Retrieved satellite aerosol optical depth (AOD) is compared to surface measured …

Simulations and projections of major air pollutants over the United States and uncertainty analyses, effects of natural change and human activities
… a better understanding on the effect of mineral dust emissions on changes in future air quality especially the PM concentrations, a physical dust aerosol module is developed and incorporated into the CAM-Chem model. A mercury module is developed for the CAM-Chem model to simulate the atmospheric …

Unraveling the Mystery of Extreme trans-Atlantic African Dust Events: Insights from Case Studies
North Africa is the world’s largest source of dust. Each summer, the Saharan Air Layer transports massive amounts of mineral dust across the Atlantic Ocean, affecting weather, climate, ecosystem, and public health across large areas. While considerable attention has been devoted to extreme events …

Aerosol-cloud-precipitation interaction based on remote sensing and cloud-resolving modeling over the Central Himalayas
… occurring from June to September. Atmospheric aerosols can influence regional and global climate through aerosol-radiation (ARI) and aerosol-cloud interactions (ACI). The study of the aerosol-precipitation relationship over the Central Himalayan region during the summer monsoon season is …

Spatio-temporal variability of aerosols in the tropics relationship with atmospheric and oceanic environments
… radiation budget is directly influenced by aerosols through the absorption of solar radiation and subsequent heating of the atmosphere. Aerosols modulate the hydrological cycle indirectly by modifying cloud properties, precipitation and ocean heat storage. In addition, polluting aerosols …
