Dust Storm Detection and Remote Sensing Techniques

Dust storms pose significant hazards to human health, aviation safety, agriculture and infrastructure across arid and semi-arid regions. Their detection and monitoring have advanced through the integration of satellite remote sensing, ground observations and numerical modelling. Passive optical sensors aboard polar-orbiting and geostationary platforms offer multispectral and thermal-infrared measurements to discriminate airborne dust from clouds and surface features by exploiting spectral signatures and brightness temperature differences. Active systems such as spaceborne LiDAR and synthetic aperture radar provide vertical profiling and surface roughness information that improve dust layer characterisation. Hybrid approaches combine satellite indices, meteorological reanalysis fields and machine-learning algorithms for real-time detection, quantification of dust aerosol optical depth and predictive forecasting. Recent developments include dynamic threshold schemes, look-up tables for physical retrievals, convolutional neural networks for semantic segmentation and data fusion frameworks that integrate ground-based lidar, sun-photometer networks and aerosol reanalysis products. Together, these techniques enhance early warning capabilities and support cross-border risk management of transboundary dust transport.

Studies on an extreme dust event over the South Mongolian Plateau employed a normalised difference dust index with MODIS surface reflectance and ERA-5 reanalysis to map storm initiation, identify dewpoint reduction and low-pressure systems as key drivers, and trace spatiotemporal transport pathways. A satellite-based retrieval from the GEOKOMPSAT-2A Advanced Meteorological Imager improved continuous daytime and nighttime monitoring of dust aerosol optical depth by exploiting infrared brightness temperature differences at 10.5 µm and 12.3 µm, with look-up tables calibrated against visible-band aerosol optical depth and validated against active lidar products. An analysis of two decades of spring sand and dust storms on the Mongolian Plateau used MODIS remote sensing data and a dust storm detection index to reveal declining storm frequency, cross-border intensity hotspots and strong negative correlations between precipitation and storm extent, underpinning the efficacy of regional windbreak and land restoration policies.
