Abstract

The present study focuses on the evaluation of dust in on-line chemistry-climate simulations with the regional climate model RegCM4. The simulations cover the period from December 2006 to November 2014 and use the new dust scheme implemented in RegCM4 that splits 12 dust size groups according to the changes of dry deposition velocity with size (isogradient method). In the model, dust is emitted over desert and semidesert grid cells when a wind speed threshold value is exceeded. This critical wind speed value varies and depends on soil particle size distribution, surface roughness and soil moisture.
