Abstract

Dust is one of the generally harmful weather phenomena that every year disrupts economic affairs and daily life, causing financial damage and threatening the physical and even mental health of people in society. This phenomenon, which is considered one of the environmental hazards in arid and semi-arid regions, is affected by the change of atmospheric conditions, and if the mechanism of its occurrence and spread is known, its damages can be reduced or at least adapted to it. The studied area includes the western and northwestern provinces of Iran. The data used in this study are divided into two categories: ground and RemoteSensing data. Based on this, the library method has been used. The ground data of 27 synoptic stations in the western half of the country and a collection of satellite images have been extracted. The current situation has been described in the environment of Excel, ArcGIS and GEE. The obtained results show that the maximum amount of dust cover was observed on the first, second, third and fourth day of July in Fars and Bushehr provinces, but the lowest index value was observed in the farthest parts of the study area, including the provinces of West and East Azerbaijan, Qom and Makrazi. Also, the main source of these dusts is outside the borders of the country and originates from the deserts of distant regions.
