“…The ''Aeolian Dust Experiment on Climate impact (ADEC)'' programme started in the year 2000 (Mikami et al 2002) to improve understanding of aeolian dust, with special emphasis on Asian dust. We established a network of nine observation stations in Asian dust-source regions, long-range transported regions in east China and Japan (Mikami et al 2002).…”

The observed maximum concentration of total suspended particles (TSP) was 5.2 mg m À3 during the dust event of April 2003. Variations in the TSP and PM 11 (particles smaller than 11 mm) show that high atmospheric concentrations were observed during dust events that occurred mainly in spring and summer. According to the meteorological observations, dust storms or blowing sand/dust occurred not only in spring, but also in summer and autumn, though floating dust occurred mainly in March and April. The frequency of dust events was consisted with the results of dry deposition.During spring and summer, the size-distribution of aerosols is unimodal with a maximum in the range 3.3-7.0 mm, while in winter the size-distribution shows a bimodal pattern with two peaks; at 3.3-7.0 mm for soil particles and 0.65-1.1 mm for anthropogenic particles. From the results of size distribution of soluble ion concentration, anthropogenic particles consist mainly of ammonium sulfate and ammonium nitrate, which result from coal combustion for heating during winter.Concerning chemical composition, aerosols from Aksu contain a significant amount of evaporate minerals such as calcium carbonate (calcite), sodium chloride (halite), and calcium sulfate (gypsum and anhydrite). These evaporates are common minerals in the saline soils which are widespread around observation site, and it is suggested that they are provided into atmosphere from the ground surface together with soil particles.Major element composition for aerosols in Aksu show a lower SiO 2 content and higher FeO, K 2 O and MgO content compared with that for the saline soils (j < 125 mm), the loess deposits in the Tarim Basin and Central Loess Plateau, and Taklimakan Desert sands (j < 125 mm). This suggests that minerals rich in Fe, K and Mg, such as clay minerals and mica, come selectively from the soil surface into the atmosphere as mineral aerosols. This is because their particle size is generally smaller than that of quartz, the main constituent minerals in the soil.

“…The MTSAT observations are used to investigate a dust event over the Bohai Sea and the Yellow Sea during 1-3 March 2008. The major conclusions are as follows: (1) Streamer is suitable to simulate the brightness temperature and the simulations can be used to create the LUT under different conditions; (2) spatial mapping of retrievals of the dust clouds with MTSAT agrees with nearly synchronous MODIS products and the correlation of dust column concentration reaches 0.85; (3) the dust column concentration decreased exponentially with the dust transport time on the pathway; and (4) the magnitude of the deposition flux is comparable to the in situ and model results from previous studies.…”

“…Dust aerosol carried by dust storm events from Asia not only damage to the local ecosystems and human society, but also have large impacts on downwind areas such as Japan, Korea, and even the West Pacific Ocean through long-range transport [1]. Dust aerosol in the atmosphere play an important role in the radiative forcing of the atmosphere via scattering and absorbing shortwave and longwave radiation [2].…”

Windblown dust aerosol plays an important role in marine ecosystems once they are deposited and dissolved. At present, methods for estimating the deposition flux are mainly limited to direct measurements or model outputs. Additionally, satellite remote sensing was often used to estimate the integral dust column concentration (DCC). In this paper, an algorithm is developed to estimate the mass deposition fluxes of Asian dust by satellite. The dust aerosol is identified firstly and then the DCC is derived based on the relationships between the pre-calculated lookup table (LUT) and observations from Japanese geostationary Multi-functional Transport Satellites (MTSAT). The LUT is built on the dust cloud and surface parameters by a radiation transfer model Streamer. The average change rate of deposition is derived, which shows an exponential decay dependence on transport time along the pathway. Thus, the deposition flux is acquired via integrating the hourly deposition. This simple algorithm is applied to a dust storm that occurred in the Bohai Sea and Yellow Sea from 1 to 3 March 2008. Results indicate that the properties of the dust cloud over the study area changed rapidly and the mass deposition flux is estimated to be 2.59 Mt.

“…Optical thickness of the Asian dust aerosols over the ocean near Japan has been successfully retrieved from the Geostationary Meteorological Satellite (GMS-5) visible measurements during the first intensive observation period (IOP-1), conducted as a part of the Japanese-China joint project on Aeolian Dust Experiment on Climate impact (ADEC) (Mikami et al 2002), by taking the nonsphericity of dust particles into account. The hourly retrieved optical thicknesses were compared with those derived from the ground based radiometer measurements; sun photometers and sky radiometers.…”

Daily and monthly aerosol optical thickness (AOT) over the ocean, derived from the Geostationary Meteorological Satellite (GMS-5) visible data, were compared with those determined from the sun photometer measurements in March and April 2002. Time variations in the daily AOT derived from the GMS-5 showed good agreements with those from the sun photometer measurements. Correlation coefficient between the GMS-5 and the sun photometer derived daily AOTs was 0.85 for 61 samples taken at three sun photometer observation sites; Ryori, Yonagunijima, and Minamitorishima in Japan.
