Soil organic carbon dust emission: an omitted global source of atmospheric CO2.
Soil erosion redistributes soil organic carbon (SOC) within terrestrial ecosystems, to the atmosphere and oceans. Dust export is an essential component of the carbon (C) and carbon dioxide (CO(2)) budget because wind erosion contributes to the C cycle by removing selectively SOC from vast areas and transporting C dust quickly offshore; augmenting the net loss of C from terrestrial systems. Howe...
متن کاملMartian dust storms as a possible sink of atmospheric methane
[1] Recent laboratory tests, analog studies and numerical simulations all suggest that Martian dust devils and larger dusty convective storms generate and maintain large-scale electric fields. Such expected E-fields will have the capability to create significant electron drift motion in the collisional gas and to form an extended high energy (u kT) electron tail in the distribution. We demonstr...
متن کاملApplication of aerosol speciation data as an in-situ dust proxy for validation of the Dust Regional Atmospheric Model (DREAM)
The Dust REgional Atmospheric Model (DREAM) predicts concentrations of mineral dust aerosols in time and space, but validation is challenging with current in-situ particulate matter (PM) concentration measurements. Measured levels of ambient PM often contain anthropogenic components as well as windblown mineral dust. In this study, two approaches at model validation were performed with data fro...
