Abstract
One of the most important pollutants that its surveillance in the atmosphere by remote sensing is possible is the suspended particles density using the MODIS sensor images. In the analyzing related to pollution study, the studies of distribution and relation between variables have an important role that the regression analyzing applications in these studies is inevitable. The main goals of this paper is preparing the particulate matter less than 10 micron distribution in Khuzestan province in both hourly/daily periods using the linear regression models the AOD product, the MODIS sensor also the ground stations data of the atmosphere pollution measurement and lateral insight of Ahvaz city in 2009 in order to estimating the pm10 were used. The results showed MODIS data have high accuracy to estimate the atmosphere pollutions and results indicates that the hourly period with R square 90% against daily period with R square 76% have a higher coefficient. After the model estimating correction by interpolating the produced plots by using the resultant relation in both time periods the suspended particles distribution maps were prepared.

Abstract
Air pollution is one of the consequences of industrial development that its severity is increasing day to day, due to the population growth and expanding urbanization, development of transport and fuel consumption increases. Awareness of air quality and trends of pollutants changes in different locations in a city can play an important and effective role in urban health management and macro policymaking. The first practical step in reducing the level of pollutants is the adequate knowledge of the pollutants details, including the type, amount and frequency of events throughout the year to determine the type of pollution and its source. In this paper, the results of hourly, daily, monthly and annual analysis of the various pollutants have been studied and scrutinized using the experimental data obtained from air quality measurement stations in the city of Saveh. In the end, In addition to the general solutions and suggestions for reducing the air pollution level in Saveh city, two precise solutions include the construction of an underpass and construction of a high way have been presented which the geometry and detailed features of each one has been mentioned in the article.
