AB: Dust storm is a severe environmental problem in eastern Asia, especially in Mongolia and northern China. Strong dust storms often occur during spring and earlier summer in this region because of desertification, windy conditions, and drought. To study the dust source, mechanism of dust transport, and effect to weather and environment, efficient approaches for dust storm detection and monitoring are critical, many efforts have been taken with ground measurements and satellite remote sensing. Moderate Resolution Imaging Spectroradiometer (MODIS) and Atmospheric Infrared Sounder (AIRS) are two of the key instruments for Earth observation of NASA EOS Aqua (EOS PM) satellite, MODIS covers the entire earth surface every 1 to 2 days and acquiring data in 36 spectral bands with spectral coverage from visible bands to thermal infra-red bands and spatial resolution of 250m, 500m, and 1km, it­_s very suitable for dust storm detection and monitoring while AIRS provide high spectral thermal measurements. We already investigated the spectral features of Asian dust storms, identified MODIS sensitive bands to dust and designed spectral indices with infra-red band and thermal band measurements from MODIS and AIRS in our previous studies. With four overpasses (two daytime and two nighttime) of MODIS (Terra and Aqua MODIS) each day and two overpasses of AIRS, we can detect Asian dust storm, and monitor the movement and transport of dust. We demonstrated our approaches with comprehensive analysis of dust storms in Mongolia and eastern China. Key words: Dust storm monitoring, remote sensing, MODIS and AIRS
