An intense dust storm occurred during 19–20 May 2007 over the TaklimakanDesert in northwestern China. Over the following days, the space-borne lidarCALIOP tracked an optically thin, highly elevated, horizontally extensivedust veil that was transported intercontinentally over eastern Asia, thePacific Ocean, North America, and the Atlantic Ocean. A global aerosoltransport model (SPRINTARS) simulated the dust veil quite well and provideda three-dimensional view of the intercontinental dust transport. TheSPRINTARS simulation revealed that the dust veil traveled at 4–10 kmaltitudes with a thickness of 1–4 km along the isentropic surface between310 and 340 K. The transport speed was about 1500 km/day. The estimated dustamount exported to the Pacific was 30.8 Gg, of which 65% was deposited inthe Pacific and 18% was transported to the North Atlantic. These resultsimply that dust veils can fertilize open oceans, add to background dust, andaffect the radiative budget at high altitudes through scattering andabsorption.  The injection mechanism that lifts dust particles into the free atmosphereis important for understanding the formation of the dust veil and subsequentlong-range transport. We used a regional dust transport model (RC4) toanalyze the dust emission and injection over the source region. The RC4analysis revealed that strong northeasterly surface winds associated withlow pressures invaded the Taklimakan Desert through the eastern corridor.These winds then formed strong upslope wind along the high, steepmountainsides of the Tibetan Plateau and blew large amounts of dust into theair. The updraft lifted the dust particles farther into the uppertroposphere (about 9 km above mean sea level, MSL), where westerlies aregenerally present. The unusual terrain surrounding the Taklimakan Desertplayed a key role in the injection of dust to the upper troposphere to formthe dust veil
