The main objective of this paper is to present analytical models relat
ing maximum pollutant concentrations in urban areas with meteorologica
l and other variables. The analysis is based on measurements from Grea
ter Athens Area and is restricted in only one pollutant of special int
erest, namely NO2. The meteorological variables, used in analytical mo
deling for forecasting pollution concentrations, cover the most import
ant atmospheric processes favoring pollution episodes. The selection o
f the variables was based both on extensive correlation analysis and o
n the existing knowledge from the scientific literature. The evaluatio
n of the developed forecasting models showed that their degree of succ
ess is promising. The final model equations derived are simple and the
y can be used easily for operational forecasts from the air quality ma
nagement authorities.
