POLLAIRO is a simulation and visualization system which calculates the 
physical behaviour of gaseous pollutants and dusts in the atmosphere 
under regular and accidental conditions.

Target users of POLLAIRO are (i) graduate and post graduate students of 
science who specialize in ecology; (ii) people involved in the governmental
or municipal licensing of industrial plants which emit pollutants into the 
atmosphere; (iii) scientific researchers in the field of pollution control.

POLLAIRO is based on a variety of mathematical models (like the Lagrangian
models in the form of various kinds of Gauss models, etc.) which enable the 
quantitative prediction and analysis of air pollution effects on the
environment. This variety of models include models for low wind speeds and 
calm situations, heavy gases, floating particles (dusts), and other special
conditions and cases. Some of the models are the result of our own research
work.

User Interface:
Particular attention has been paid, in designing POLLAIRO, to the graphical
user interface. POLLAIRO allows for easy and intuitive interaction between the
user and the software system and provides static and dynamic visualization of
the simulation results.

The user interface is available (at the moment) in English and German. 
POLLAIRO can be easily adapted to other European languages (Chinese, Japanese,
Arabic, etc. are, of course, more difficult).

Intended Usage:
POLLAIRO was designed to be used interactively to determine the physical
behaviour of various kinds of air pollutants in the atmosphere. Many 
parameters of the emitting source, the meteorological conditions, etc. 
can be chosen and modified interactively. The consequences of a specific
choice of parameters can be studied using a number of selectable 
dispersion models. Visualization techniques can lead to insights into the
dispersion process.

Result of Field Trials:
All models involved have been validated by comparing POLLAIRO simulation 
results with pollutant concentration values measured under real atmospherical
conditions. For instance, there was satisfactory agreement between values
obtained from measurements taken in the vicinity of a thermal power plant in
Austria (Duernrohr) and results obtained using POLLAIRO.

POLLAIRO has been used for some time now in the Department for Environmental
Protection (in the municipality of Vienna) licensing procedures, where
POLLAIRO has proven itself to be useful and accurate.

POLLAIRO has been installed at the Department of Environmental Chemistry
(Prof. Puxbaum) at the Technical University of Vienna, where it serves
scientific and educational purposes.

Educational Benefits:
Simulation is the only possible way to practically demonstrate to students the
dispersion of pollutants into the atmosphere. In particular the temporal
variation of the distribution of pollutants can only be shown with the help of
animated simulation techniques found in POLLAIRO.

Features Enabling Adaptation:
POLLAIRO was designed so that parameter changes and other modifications can be
made easily and simply. For instance, changing the language of the user
interface requires only the replacement of several text files.  Special
features of the mathematical models can be modified by changing few internal
parameters, etc.

Differences to Existing Programs:
No single program offers the same comparable features.  POLLAIRO is the first
program to combine a wealth of relevant air pollution models with advanced
visualization techniques, including animation.

The Software is available for UNIX systems with X11R5 and Motif 1.2. 
Ready made binaries are available for HP-Workstations and IBM-Workstations.
Other hardware platforms are available upon request.

The Software can be ordered from the Institute of Applied and Numerical
Mathematics, Department of Numerical Mathematics E115/2 at the 
Technical University of Vienna. Contacts via e-Mail to

A complete user manual is available as a postscript file via anonymous/ftp
from "uranus.tuwien.ac.at". The file in the directory "/pub" and has the name
"pollairo.ps" (aprox. 16MB).
