East Asia is one of the major source regions of mineral dust aerosols in the world. Every year, deserts in Eastern Asia produce a large amount of mineral dust particles that become entrained in the atmosphere. Fully accounting for aerosol effects on climate requires extensive measurements of aerosol optical, microphysical and chemical properties, and their spatial and temporal distributions. To improve understanding and capture the direct evident of the impact of dust aerosol on climate, 6 years ground-based observations and 3 year field campaigns have conducted over Northwest China. These studies are vital to understand the characteristics and variations of dust aerosols in East Asian so that we can evaluate more accurately the effect of mineral dust aerosols on regional climate change in the future. This talk presents a description the objectives, measurements, and sampling strategies for those campaigns. Those observation results suggest that the local anthropogenic and nature absorbing aerosols make significant contribution to the regional interaction among aerosol-cloud-radiation-precipitation processes and need to be future investigation.
