Dust is influenced by the interaction of the atmosphere-Earth system and, by changing radiation energy, atmospheric chemistry and physics, affects the climate of an area. Due to the necessity of the role of dust and its spatial-dynamic distribution in the atmosphere of a region, as well as the existence of advanced remote sensing techniques and modeling in the field of dust simulation, the present study attempts to compare, quantize and simulate dust using aerosol optical depth (AOD) of MODIS and MACC products. Pearson correlation showed that there is a significant relationship between the sensor and the model in the west of the interested area. The lowest correlation was observed over Hamadan province. The results showed that simulated dust was more than satellite observations. The annual dust revealed that dust have two active (2000-2010) and inactive from 2010 onwards. In addition, monthly distributions of Dust in MODIS and MACC showed that the interested area had the highest dust concentration in the months of April to August; it was high overlaps of AOD between MACC and MODIS in the wet months (December to March) than dry month (April to November). In general, the spatial distribution of dust in the study showed that the dust pattern in both the sensors and the model has increased from south to north in Kurdistan, Kermanshah and Ilam, but the spatial variation of dust in the MODIS is more regular than the MACC. In general, the spatial distribution of dust had the South-North trend and northward decreased
