LONG-RANGE TRANSPORT OF SAHARAN DUST FROM CALIPSO, AIRBORNE AND GROUND-BASED LIDARS, AND A REGIONAL MODEL DURING COPS
A Saharan dust event affected the Rhine valley in southwestern Germany and eastern France on 1 August 2007 during the Convective and Orographically-induced Precipitation Study (COPS) experiment. Prior an episode of intense convection, a layer of dry and clean air capped by a warm and dusty layer was...
