Hi SoundPLAN Air Pollution.!.

Hi SoundPLAN Air Pollution.!.

SoundPLAN:

Many planning processes require calculations for noise emissions and air

pollution dispersion. 

It is welcome news to hear SoundPLAN has a uniform software interface 

for both types of calculations so users can work efficiently in both areas of 

expertise.

SoundPLAN builds a comfortable bridge between science and engineering:

Embedding scientific calculation kernels in the user friendly interface

of SoundPLAN and adding specific tools for data control, data conversion

and result presentation, SoundPLAN creates an environment for high

efficient air pollution dispersion calculation, benefitted from over 25 years

of noise programming experience.

Modular Architecture:

The modules offered by SoundPLAN are spread from a "simple"

Gauss model up to complex prognostic models. 

The model selection depends strongly on the requested task and the

available input data. 

Therefore the modules can't replace each other. 

It is not sensible to start with the simpler models Gauss and Austal2000,

which were mainly designed for industry licensing procedures, if your 

work is focused on roads or complex terrain. 

You should know details about the model borders, before you decide to buy.

Base Module Air Pollution:

The Base Module Air Pollution generates the environment where all modules are embedded. 

Besides the basic modules for data input, calculation and result presentation it contains special air pollution library tools which are designed to make your work easy, efficient and transparent.  

If you own already a SoundPLAN license, no matter if it is for acoustics or air pollution, the base module is discounted by 50%.

^{Gauss TA Luft 86:}

^{Gauss TA Luft 86} is a model for quick estimations: 

The formulas of the former German standard "TA Luft '86" are suitable for approximate calculations, e.g. to estimate background concentrations or to make worst case studies, whenever free flow conditions can be assumed around emission sources.

GRAL system:

GRAL system contains of two programs. 

The highly recommended Austrian Lagrange particle dispersion model GRAL is suitable to include traffic sources in street canyons. 

It uses optionally a diagnostic wind field approach or a mixed approach, which can take explicitly buildings into account by calculating a prognostic wind field for a limited area around the buildings.

Also tunnel portals can be modeled. 

To show up its full strength GRAL should be used with pre processed prognostic mesoscale GRAMM wind fields. 

GRAMM was developed in the complex topography of the Austrian Alps and is capable to regard strongly undulated terrain, and differentiated land use.

MISKAM advanced: 

The MISKAM kernel is mainly designed for highly resolved street canyons in urban quarters. 

The fine grid resolution starts where GRAL ends. 

Therefore those two models complete each other in a most sensible way. 

The established, highly recommended and steadily validated prognostic wind field model is ideal for detailed studies, when air movements around buildings suppress thermal effects.

The former SoundPLAN interface for MISKAM, as SoundPLAN module also simply named MISKAM, didn't support the full functionality of the MISKAM kernel. 

This slim version is still maintained for customers with a continuous maintenance contract, but it is no longer sold. 

In winter 2013/14 it will be replaced by the new module  MISKAM advanced, which provides additionally underflow of buildings, flow-through of vegetation and a 64 bit version.

Intermediate solution: 

If you mandatory pre order MISKAM advanced, you'll get the current interface for the old price and we invoice the rest, when you receive MISKAM advanced. 

As soon as you receive MISKAM advanced, the full update and maintenance period is restarted.

Current MISKAM users will get a special upgrade offer as soon as MISKAM advanced is released.

AUSTAL2000 interface:

AUSTAL2000 is the public domain reference model of the current German directive "TA Luft 02". 

The model input and output is strictly designed to fulfill the demands of German directives (supports directive 2008/50/EC) and needs a professional interface like SoundPLAN to work efficiently. 

A more flexible kernel version was announced for 2012 but it is not yet released.
