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...

Modeling the Martian dust cycle 1. Representations of dust transport processes

A dust transport scheme has been developed for a general circulation model of the Martian atmosphere. This enables radiatively active dust transport, with the atmospheric state responding to changes in the dust distribution via atmospheric heating, as well as dust transport being determined by atmospheric conditions. The scheme includes dust lifting, advection by model winds, atmospheric mixing...

Modeling the Martian dust cycle 2. Multiannual radia- tively active dust transport simulations

Multi-annual dust transport simulations have been performed using a Mars general circulation model containing a dust transport scheme which responds to changes in the atmospheric state. If the dust transport is ‘radiatively active’ the atmospheric state also responds to changes in the dust distribution. This paper examines the suspended dust distribution obtained using different lifting paramet...
