[ 1 ] - Modeling of Air Pollutants’ Dispersion by Means of CALMET/CALPUFF (Case Study: District 7 in Tehran city).

The current study aims at modelling the dispersion of two pollutants, namely CO (carbon monoxide) and SO2 (sulfur dioxide) released from District 7 of Tehran Municiaplity, from 20 main line sources, by means of CALPUFF modeling system. CALPUFF is a non-steady state puff modeling software which employs meteorological, terrain, and land-use data to effectively simulate air pollutants' dispersion ...

[ 2 ] - Evaluation Euro IV of effectiveness in transportation systems of Tehran on air quality: Application of IVE model

The quick growth of vehicles is due to fast urbanization in mega cities during last decades. This phenomenon has serious impacts on air quality, as emission from mobile vehicles is the major source of air pollution. As a result, any attempt to reduce the emitted air pollutants is needed. This study aims at improving the fuel quality in transporting system with particular emphasis on taxis in Te...

[ 3 ] - Identification of the sources of dust storms in the City of Ahvaz by HYSPLIT

Dust particles have dangerous impacts on human health, the environment, and the economy. Recently dust storms, originating from Arabian countries, have increased remarkably, affecting western and central parts of Iran.HYSPLIT model and the mean monthly maps of AAI (Absorbing Aerosol Index), surface skin temperature, and top soil layer moisture from OMI (Ozone Measurement Instrument) have been u...

[ 7 ] - منشاء یابی ذرات گردوغبار با بررسی خصوصیات فیزیکی و شیمیایی آنها و مدلسازی عددی در شهرستان مسجد سلیمان

Background and Objective: The aim of this study was to investigate the physico-chemical properties, size distribution and shape of the falling mineral dusts over Masjed Soleyman and to identify their origins. Also, seasonal and annual variations of climatic parameters and their relation with dust storm occurrence were investigated. Materials and Methods: The collected samples were as result ...
