Husar at CAPITA but its content is contributed by the community members.

2. Dust Storm and Biomass Smoke Over SE Asia Starting on March 15, 2002 was an active aerosol period over SE Asia The first springtime Gobi dust cloud was streaking along the Mongolia-China border toward the Pacific The seasonal biomass burning over Indochina produced a thick, bluish, 1000++ km smoke plume Biomass Smoke Gobi Dust SeaWiFS Team, Gene Feldman, Norman Kuring, norman@tursiops.gsfc.nasa.govnorman@tursiops.gsfc.nasa.gov All SeaWiFS images are for research and educational use only. All commercial use of SeaWiFS data must be coordinated with ORBIMAGE

3. NRLNRL Surface Winds and Visibility Forecast winds predicted friction velocity well over the critical 60 cm/sec for the Gobi Desert. High Friction Velocity Doug Westphal, westphal@nrlmry.navy.mil Surface visibility observations at the synoptic network indicate low visibility and dust in the air (blue markings)

5. Dust Transport: NRL ModelNRL Model On March 15, the NRL dust model shows the dust cloud emerging from the Gobi desert By March 20, another strong dust plume is predicted See the animation that illustrates the transport dynamicsanimation D. Wespthal, westphal@nrlmry.navy.mil

6. MODISMODIS High resolution Images High resolution from the MODIS sensor are now available a few hours after data acquisition (March 15, 2002) The MODIS images show the texture of the dust cloud: low level dust streaks and palls MODIS 250 m resolution Rapid Processing Team

10. AERONETAERONET Sun Photometer Data: Dalanzadgad Dalanzadgad, Mongolia was in the path of the March 15 Gobi dust cloud On March 16, the aerosol optical thickness was about 2 The wavelength-independence of AOT indicates that the vertical light extinction is due to dust Brent Holben, brent@aeronet.gsfc.nasa.gov

15. TOMSTOMS Absorbing Aerosol Index, March 15 - By the TOMS Aerosol Group On March 15, the dust cloud was near the surface TOMS did not register the low- level dust By March 17 and 18, the elevated dust cloud is over the Sea of Japan and the Pacific. Also, note the intense biomass smoke plume emanating from Indochina. On March 16, a strong dust signal emerges over N Korea/NE China Evidently, the dust layer is elevated to several KM.
