aerosol impact on people health, social and economic activities, land and water ecosystems and meteorological parameter. the gocart scheme was evaluated for simulating pm10 in this study. gocart was run into wrf model as a host model. reanalysis data from fnl for every 6 hour was used for initial conditions. one domain and two nests were used to cover region from west africa till east asia, ira...

This paper describes spatial modeling methods to identify wind erosion hazard (WEH) areas across Australia using the recently available time-series products of satellitederived ground cover, soil moisture and wind speed. We implemented the approach and data sets in a geographic information system to produce WEH maps for Australia at 500 m ground resolution on a monthly basis for the recent thir...

We describe a model for predicting the size-resolved distribution of atmospheric dust for climate and chemistry-related studies. The dust distribution from 1990–1999 is simulated with our mineral aerosol entrainment and deposition module embedded in a chemical transport model. Mobilization processes include entrainment thresholds, moisture inhibition, drag partitioning, and saltation feedback. ...

Erosion process occurs naturally, shaping the Earth’s surface. Soil loss can cause harmful effects to environment when intensive anthropic activities occur. Mathematical models have been used as effective and less costly alternatives for identifying sites highly prone soil loss, especially at watershed scale. In Brazil, Revised Universal Loss Equation (RUSLE) is one of most commonly prediction ...

IVind ttiimel tests on silty textured loessial soils throtigbout the Cohimhia Plateau of eastern Wa.shiitg{on slate and northern central Oregon were used ro define soil erndibiltiy for wind erosion predictions. Aggregate and primary particle size distributions were determined hy common techniques and correlated wiih the wind tunnel erosion values. Dry aerodynamic particle sizing by a laser meth...

Some methodologies were compared in providing erosion maps of surface, rill and gully and erosion features, in research which took place in the Varamin sub-basin, north-east Tehran, Iran. A photomorphic unit map was produced from processed satellite images, and four other maps were prepared by the integration of different data layers, including slope, plant cover, geology, land use, rocks erodi...
