“…An increase in the earth's reflectance is the most distinctive feature in satellite imagery for detecting particulate matter, and has been observed since the earliest days of satellite use. A thick aerosol layer such as from large-scale dust storms or forest fire events can easily be detected by an enhanced reflectance in a visible channel as noted by many investigators (Griggs 1975;Fraser 1976;Mekler et al 1977;Quenzel and Koepke 1984;Takayama and Takashima 1986;Kaufman et al 1990a). The NOAA operational one-channel algorithm has been successful at depicting global optical thickness distributions of stratospheric and tropospheric aerosols over the ocean (Stowe et al 1992;Long and Stowe 1994;Husar et al 1997).…”

Tropospheric aerosol particles originate from man-made sources such as urban/industrial activities, biomass burning associated with land use processes, wind-blown dust, and natural sources. Their interaction with sunlight and their effect on cloud microphysics form a major uncertainty in predicting climate change. Furthermore, the lifetime of only a few days causes high spatial variability in aerosol optical and radiative properties that requires global observations from space. Remote sensing of tropospheric aerosol properties from space is reviewed both for present and planned national and international satellite sensors. Techniques that are being used to enhance our ability to characterize the global distribution of aerosol properties include well-calibrated multispectral radiometers, multispectral polarimeters, and multiangle spectroradiometers. Though most of these sensor systems rely primarily on visible to near-infrared spectral channels, the availability of thermal channels to aid in cloud screening is an important additional piece of information that is not always incorporated into the sensor design. In this paper, the various satellite sensor systems being developed by Europe, Japan, and the United States are described, and the advantages and disadvantages of each of these systems for aerosol applications are highlighted. An important underlying theme is that the remote sensing of aerosol properties, especially aerosol size distribution and single scattering albedo, is exceedingly difficult. As a consequence, no one sensor system is capable of providing totally unambiguous information, and hence a careful intercomparison of derived products from different sensors, together with a comprehensive network of ground-based sunphotometer and sky radiometer systems, is required to advance our quantitative understanding of global aerosol characteristics.

“…Also, in the spring, strong westerly flow in the midlatitudes favors the transport of dust over great distances [Merrill, 1989;Duce, 1995;Prospero et al, 1989;Gao et al, 1992]. In Japan and Korea during the spring, they frequently experience extensive hazes that are caused by yellow dust (Kosa) that can be traced to sources in Asia [Takayama and Takashima, 1986;Tsunogai et al, 1985;Mukai, 1990;Uematsu et al, 1992]. Asia is also a major source of anthropogenic sulfur and nitrogen emissions [Hameed and Dignon, 1992 Midway (28.22øN, 177.35øW) which lies at the southern edge of the plume in MAM (Plate 1), there is a strong spring maximum in dust concentration (Figure 7).…”

where anthropogenic emissions are greatest) the summer/winter ratio is about 3. The temporal variability of monthly mean EAOT in specific ocean regions often shows characteristic seasonal patterns that are usually consistent with aerosol measurements made in the marine boundary layer. Nonetheless, there are features in the EAOT distributions that can not be readily interpreted at this time. The AVHRR EAOT distributions demonstrate that satellite products can serve as a useful tool for the planning and implementation of focused aerosol research programs and that they will be especially important in studies of climaterelated processes.

“…For example, the ADSs produce severe visibility reductions with lowest visibility of less than 200 meters. The ADSs can significantly affect the human's health, causing respiratory symptoms and eye trouble (Takayama and Takashima, 1986;Kim et al, 2002). As pointed out by Mikami et al (2009), the ADSs also have important effects on weather and climate change.…”

A severe dust storm (SDS) event occurred during March-20 to March-22, 2010 in China. A regional dynamical model coupled with a dust model (WRF-Dust) is used for analyzing this SDS event. The distribution of API (air pollution index) values in China and satellite (moderate-resolution imaging spectroradiometer-MODIS) AOD (aerosol optical depth) data are used to trace the dust storm and to compare with the model result. Several model sensitive studies are performed to analyze the roles of physical processes (such as dust source, transport, and deposition) in controlling the SDS event. The result suggests that the Gobi Desert is a major dust source of the SDS event. By contrast, the Taklamakan Desert plays minor roles for affecting the high dust concentrations in eastern/southern China during the SDS event. This study also suggests that a large amount of dust particles was deposited at the surface during the transport pathway between the Gobi Desert and eastern/southern China, and the high surface concentrations of dust particles can be considered as a new dust source region, which produced dust air pollution when surface winds were strong. In this study, we define this process as a propagate dust source (PDS). The calculation shows that the calculated dust concentrations were considerably lower than the measured values in the downwind regions of deserts when the PDS process was not included in the model. By including the PDS process, the calculated dust pollution in eastern and southern China is considerably improved. The further detailed analysis shows that the PDS played important roles in controlling the long-range transport of dust particles during the SDS event. This study suggests that this regional dust model (WRF-Dust) is a useful tool to analyze the important processes of dust storms that are often occurred in China.
