This value is one … WebMay 15, 2002 · A dust index constructed by winter air temperature and spring cyclone frequency is described in section 6. Finally, the conclusions are drawn in section 7. 2. Data and methods In this paper, all three phenomena: dust haze, blowing dust, and dust storms, are referred or defined to dust weather. Five datasets will be used.

Applying a dust index over North China and evaluating the …

WebThe index introduces dust optical density (α), which can be simply estimated by spectral unmixing, into the normalized difference between reflectance at near-infrared (2.13 μm) and blue (0.469 μm). Dust severity can thus be rated from weak to severe within a standard range of –1 to 1. WebMar 21, 2024 · An enhanced dust intensity index (EDII) is developed based on the reflectance of visible/near-infrared bands, BT of thermal-infrared bands, and aerosol optical depth (AOD), and is applied to... dan buller city of spokane

Impact of Arctic amplification on declining spring dust events in …

WebJun 4, 2014 · This weakness impelled us to develop a new model based on Ackerman's technique because of its more precise results in dust source identification. In this new presented model called Middle East Dust Index (MEDI), BT 29 was involved to highlight the difference between dust and desert surfaces as the [(BT 31 –BT 29)/(BT 32 –BT 29)] … WebDust storms significantly reduce visibly and pose a human health threads. They also cause a significant impact on the radiative regime. As a result, dust storms may cause a decrease in temperature during daytime of up to 16 о С and an increase in temperature during night time from up to 7 о С compared to a clear day.
