Atmospheric stability classification is required to quantify the dispersion capabilities of the
ambient atmosphere (ie the dispersion coefficients or the standard deviation of …

A numerical model which simulates the dispersion of passive scalars within an urban
canyon is proposed and some initial verification of the model undertaken. It is then used to …

Standard deviations of concentration in horizontal andvertical directions ie σy andσz have
been estimated by using fivedifferent schemes based on empirical (due to Pasquill and …

In this study various surface layer parameters, fluxes, and eddy diffusivity profiles have been
estimated by making use of routine meteorological data for both unstable and stable …

A new mathematical model (IIT Air Quality Model or IITAQM) is developed to retain all the
desired features of a Gaussian model while at the same time overcoming most of the …

Meteorological analysis is performed in order to have a better understanding of the wind
patterns in the Rhône valley (Valais). Circular variances and vectorial correlations of the …

The effect of increasing atmospheric aerosol and air pollutant concentration upon the solar
albedo and consequently upon the heat budget near the earth's surface is studied. The …

Um die atmosphärische Zirkulation im Rhonetal besser zu verstehen, wird eine
meteorologische Untersuchung durchgeführt. Die Zirkulationsvarianzen und die …
