Emission Patterns and Model Validation of Some Pollutants over Greater Cairo
Abstract
The highly populated Greater Cairo (GC) region suffers from severe air quality issues caused by high levels of anthropogenic activities, such as agricultural burning events, along with natural sources of air pollution, such as dust. The present study aims at studying environmental pollution over this region. The emission patterns of some pollutants, for example, NO2, SO2, CO, ozone, and PM10, were analysed using numerical model (RegCM). This study also evaluates the numerical model outcome with actual environmental data estimated from several pollution stations distributed around Greater Cairo. Quality control of the observed data was done and only particular stations were selected according to certain rules. RegCM was found to succeed in some processes, such as simulating the seasonal cycle of the pollutants, but was not very accurate in another, such as being overestimating in some values. The validation of the numerical model indicated that emissions inventories of anthropogenic activities need to be improved in order to improve air quality simulations in this GC region.
