Description
Abstract:
The dynamics of dust emission and deposition in the grasslands of Inner Mongolia were investigated during two measuring campaigns in spring months 2005 and 2006 in grazed and un-grazed plots in Inner Mongolia grassland. # Both processes are determined by the grazing intensity, whereas dust deposition rates are modified additionally by the topography. Because grazing intensity of the previous year influences the height and density of standing death vegetation, it could therefore be measured through the surface roughness length (z0). Fine dust concentrations and wind velocity were measured during dust storm events
Technical Info:
In the kml file "magim" you can find all information on parameters measured at different points.
Particulate matter was only measured on one site: x_coord 473385 / y_coord 4822040 in 3,3 m height. Coordinate System: UTM (WGS84) 50 N
