Theoretical Optimization of Troposphere Ionization Exchange Points to Reduce the Concentration of Fine Dust in Ahvaz City, Iran

The dust crisis and the numerous problems caused by it, which have affected most of the Western and Southwestern regions of Iran in recent years, need an appropriate and cost-effective solution to improve living and respiratory conditions without adverse human or environmental effects. The purpose of this study was to analyze the location of injection technology equipment to reduce the concentration of fine dust in Ahvaz City, Iran.

This theoretical study was performed based on the results of previous experimental data on the effect of atmospheric ionization in a radius of about 100km from the center of Ahvaz City, Iran. In this theoretical study, the effective exchange points of electromagnetic fields were redirected in the covered area based on satellite data and electric field information of the earthchr('39')s surface and troposphere. For this purpose, a triple combination of quasi-experimental method of latitude ionosphere model, Lagrangian distribution model and atmospheric chemical arithmetic model was used. Mathworks Matlab R2020b and Envi 5.3 software were used for processing.

According to theoretical calculations and change of atmospheric parameters by applying location corrections, the concentration of fine dust in dust conditions less than 700 micrograms per cubic meter can be reduced by 5-11% and in dust conditions above 700 micrograms per cubic meter by about 21-3%. Precipitation can also increase by 3-13%.

Dynamic location of troposphere ionization equipment can reduce the concentration of fine dust by 3 to 21% and increase precipitation by 5 to 11% in Ahvaz based on theoretical calculations.
