Analysis of atmospheric dust and aerosol extinction

Context. It is known that the Canary Islands are normally affected by dominant winds flowing from north-northeast, that in some meteorological conditions, can transport sand from the Sahara desert at high altitude. The dust may affect the efficiency of the telescopes and decrease the transparency of the sky. Aims. To maximize the scientific return of the telescopes located at the Observatorio d...

Effects of atmospheric dust deposition on leaf chlorophyll fluorescence parameters of cow-tail shrubs (Smirnovia iranica) in the desert regions of Kashan, Iran

Europeanglacial dust deposits: Geochemical constraints on atmospheric dust cycle modeling

For a long time global paleodust numerical simulations have greatly underestimated dust sources other than modern deserts. Recent modeling experiments incorporating glaciogenic sources of dust have positively improved the agreement between model and paleodust data. This highlights the importance of accurately representing all areas potentially subjected to deflation during an investigated inter...

Atmospheric global dust cycle and iron inputs to the ocean

[1] Since iron is an important micronutrient, deposition of iron in mineral aerosols can impact the carbon cycle and atmospheric CO2. This paper reviews our current understanding of the global dust cycle and identifies future research needs. The global distribution of desert dust is estimated from a combination of observations of dust from in situ concentration, optical depth, and deposition da...
