Description:
Over a period of 12h, the deposition rates of airborne dust during three dust storm and haze events in March and April 1999 at Lanzhou (36^oN, 104^oE) decreased successively from 0.43-2.23@mgcm^-^2min^-^1 in initial 2-h intervals to 0.05-0.08@mgcm^-^2min^-^1 in final intervals. Simultaneously, the mass median diameter of the falling dust decreased from 33.3-40.2 to 24.2-32.1@mm. The rate of dust deposition during dust storm and dust haze events was 10-25 times higher than the annual average (0.025@mgcm^-^2min^-^1), and a single dust storm or haze event contributed about 3% to the annual dust deposition flux (1.33.10^4@mgcm^-^2yr^-^1). However, particulate matter
