Dust lifting model

Report on dust liftingDust lifting depends on a number of parameters like grain size shear stress atmospheric pressure and gravity A model for lifting of sand and dust size grains will worked out starting from an initial state of the art model modified by results of the projects This includes equations for lifting thresholds equations for resuspended mass flux and the initial particle properties of resuspended dust These findings will be deduced from experiments where grains are observed und different conditionsEspecially the lifting of dust will be studied in individual collisions with observations at high spatial and temporal resulution
