AB: Frequent dust storms, high pollution levels, and complex flow patterns make the Southwest Asian heterogeneous environment one of the most difficult areas to understand and forecast. But, the regions surrounding the Arabian Gulf and Sea are an outstanding natural laboratory as well. For example, the atmospheric flows make Southwest Asia a "climatological crossroads" for Asia, Europe, and Africa. High modulation between pollution and dust makes it an outstanding Cal/Val site for a number of space and ground based remote sensors as well as mesoscale models. Stratus and convective clouds under a variety of environmental conditions can be studied near-simultaneously. In summer of 2004, the United Arab Emirates Unified Aerosol Experiment (UAE2) was performed by 60 researchers from 15 international organizations with 2 research aircraft and 15 ground sites, including the densest meso-net of AERONET sun photometers ever deployed. A long-term regional measurement program is now forming. This talk will give an overview of the UAE2 mission, its participants, the general properties of the Southwest Asian atmosphere and discuss future work. We will also emphasize microphysical aspects of regional dust, and note significant differences of Southwest Asian dust to that of other regions of the world.
