 p The PACKAGE:  The complete package IMMPROG consists of the dispersion models IMMPROG -P, -H (and their combination: K), -M, -C, -A and -S for inert pollutants, as well as of the module IMMPROG-G for odors.

All those programs meet the high quality standards recommended by the German and Swiss meteorological services. The user-interface common to all IMMPROG programs considerably smoothens the learning curve. And, for each menu item a context sensitive help can be displayed on the screen.

p IMMPROG-GP: The point source model IMMPROG-P is a Gaussian plume model according to the German guideline TA Luft. However, it can be used in a significantly enhanced mode including dust immission and depositions and vertical jet calculation for impulsive plumes. IMMPROG-P is used to calculate concentration fields from domestic heating, industrial stacks, and street tunnel air-conditioning outlets.Both area sources and obstacles obstructing the propagation pathway can be taken into account.

The odor dispersion module IMMPROG-G, including both Factor-10 and VDI 3781 Page 4, allows to calculate the percentage of time with nuisance by odor.

p IMMPROG-HSCM (K): The line source model IMMPROG-H implements an improved version of the U.S. Environmental Protection Agency’s Hiway-2 model. IMMPROG-H features an improved correction for weak wind speeds derived from extensive measurement campaigns. IMMPROG-H is ideally suited for calculations of concentration fields from streets located in either in flat terrain or in a small cutting. IMMPROG-H may be combined with IMMPROG-P (IMMPROG-K).

The line source model IMMPROG-C implements the canyon plume-box model (CPB). It is ideally suited to compute concentration fields of inert gazes from street-canyons, covering almost 75% of all streets inside town centers. Finally, the MLuS-92 regression model calculates concentrations of benzene, lead, hydrocarbons ...

p Working on Projects …: Graphics can be drawn from all results (averages of additional and total concentration, I-value, percentile, level overflow, etc.) calculated for an unlimited number of receptors and an unlimited number of point, area or line sources. In addition, extensive statistics (i.e. daily variations) and all input data can be graphically presented. All graphics, including overlays (e.g., grids and isolines), can be exported.

Edit the site map in graphics mode: move sources using the mouse, and display a scanned area map in the background. Scaleable graphics and all text information can be both printed on all WINDOWS-compatible printers, and exchanged with other programs via clipboard or BMP files.

The current state of progress of all calculations is dynamically displayed as a percentage value. Time required for calculation is displayed as an estimated value. Relying on 32-bit Windows multitasking capabilities, IMMPROG handels project calculation in the background, while you are continuing to work with any other application in the foreground!

Input data required by the program can be imported from existing files, edited using the built-in screen masks or data-base files.

IMMPROG directly supports the following import formats: German DWD (Deutscher Wetterdienst), Swiss SMA (Schweizerische Meteorologische Anstalt), and other meteorological data. A maximum of 5 meteo files is supported each containing an unlimited number of hours or classes. This allows for calculations on huge areas, e.g. complete urban sites, provinces, counties, ... Edit the meteo data using one of the multiple functions available (e.g. turn the wind direction, generate a class statistic from meteo hours, filter meteo data, etc.). On user-demand, the program generates typical rural or urban background concentrations of O3 , NOx, NO2, SO2 and CO, yearly pollution cycles of road traffic, domestic heating and/or industrial activities, or inversion height. In addition to concentration of inert gazes, the program calculates the transformation of NOx to NO2.

Input background pollution in graphics mode. Up to 6 background pollution cycles can be selected in the meteo file. Terrain data can be entered in graphics mode. If desired, it will be used in combination with inversion height. For up to three distinct source types each (e.g. industrial stack, road and domestic heating) a different time-dependent contribution to total emission can be specified.

Regression analysis allows for in-depth study and calibration of calculated results combined with real measurement. Emission model for road traffic and calculation of stack heights according to German TA Luft, generally expensive options with other models, are smoothly integrated into IMMPROG.

IMMPROG air dispersion modelling software has been developed according to recommendations formulated by the Swiss Federal Office for Environment, Forest and Landscape (see LEUTERT, [8]). They simulate the concentrations of inert air pollutants (=IMMISSION) emitted from point sources (IMMPROG-P), from vehicles on streets in open terrain (IMMPROG-H) and on streets in residential areas (street canyon model, IMMPROG-C). The three dispersion models are based on the Gaussian approach which itself is based on an analytical solution of the fundamental advection-diffusion equation describing the transport and diffusion of pollutants in the atmosphere. Gaussian models may thus be applied to many different types of emitting sources: whereas the P model is well-suited to the simulation of the concentration of air pollutants emitted by point sources (exhaust pipes, chimneys etc.), the H and C models can be applied to line sources (streets). The H-model should be used to calculate the resulting impact of air pollutants emitted by vehicles on a street in open terrain, the C-model in a street canyon. The P- and H-models can be used as a combination named IMMPROG-K, where K signifies Kombi). IMMPROG-G (where G signifies smell (Geruch, odour)) is an additional module to IMMPROG-P.

IMMPROG-M is a simple regression-model for the calculation of immissions near the streets (MLuS-92, see [18]).

The models are menu-driven and their manipulation is straightforward. The whole IMMPROG series follows exactly the same menu; once you have become familiar with one of the models you will be able to quickly produce results with any other IMMPROG model. Professionals with a wider interest and a need for more advanced IMMPROG applications may find helpful information in the User's Manual or are encouraged to contact the AirInfo experts. We will be happy to demonstrate you the wide variety of IMMPROG solutions for your air pollution strategies. You will find that IMMPROG models offer considerably more, while at a lower price, than any other dispersion models for inert air pollutants.
