The Aerosol Optical Depth (AOD) is a measure of solar attenuation by the particles in the atmosphere (dust, smoke haze etc.). A higher value of AOD indicates higher loads of atmospheric pollutants. AOD has been used as a matrix to investigate dust storms and pollution studies41,42,43. The area-averaged (5 °N–30 °N, … See more Figure 1 shows the time evolution of dust storm using the satellite image of Moderate Resolution Imaging Spectroradiometer (MODIS) and dust scores from … See more The AOD from reanalysis (MERRA-2 and CAMS) are compared with MODIS AOD to investigate their variability during the study period (June 1–30, 2024) … See more The angstrom parameter (ANG) explains the spectral dependence of aerosols. Additionally, it serves as a proxy for the size of the pollutant present in the atmosphere. … See more The time-averaged cross-platform AOD values are shown in Fig. 5.
