“…For examples, brightness temperature difference (BTD) between 10.5 μm and 12.5 μm channels from Temperature Humidity Infrared Radiometers (THIR) had been used for dust storm detection over land in the early seventeenth of 20th century (e.g., Shenk and Curran, 1974). Thereafter, various mineral dust detection algorithms have been developed using VS and/or near IR channels (Tanré and Legrand, 1991;Kaufman et al, 2000;Miller, 2003;Qu et al, 2006) and thermal IR wavelengths (Ackerman, 1989;Legrand et al, 1989;Ackerman, 1997;Wald et al, 1998;Legrand et al, 2001;Darmenov and Sokolik, 2005;Evan et al, 2006;Verge-Depre et al, 2006;Hao and Qu, 2007) or their combinations (Roskovensky and Liou, 2005;Hansell et al, 2007;Zhao et al, 2010). Uniformity test of the scene has also been shown to be useful for discriminating homogeneous dust layers from clouds (Martins et al, 2002), especially over ocean.…”
