The climatology of dust storms during the nighttime in northern China and Mongolia (33°N–54°N, 73°E–136°E) is characterized and compared with that at daytime at a 1-km resolution based on Aqua/MODIS thermal observations during 2002–2013. The dust was extracted with the dynamic reference brightness temperature differences (DRBTD) dust detection algorithm. The spatial distribution and seasonal and annual...
With increasing land degradation and deforestation, dust storms have been an essential factor of air pollution and global climate and biogeochemical cycle. A new index, Thermal Infrared Integrated Dust Index (TIIDI), has been developed to detect dust over land and ocean. This dust detection algorithm is based on brightness temperature difference of four thermal infrared channels, including BTD3.7-11,...
Using MODIS data over China for the 2000-2008 period, we performed a statistical analysis of the apparent reflectance difference of two blue bands (BRD) between the 469nm and 415nm over ocean and land. The results showed that the BRD gives a discrimination of heavy biomass burned smoke and dust from others phenomena such as cloud, snow/ice, haze and clear-sky surface. It indicates that the MODIS blue...
