SAMS Global - Immissionsberechnung bei Schadensereignissen

System for the calculation of air pollutant

concentrations during and after accidentalreleases


What is SAMS-Global?

SAMS-Global is a software system for the simulation of the dispersion of air pollutants during and after an accidental release at stationary (fixed installations) or mobile (for example transportation) sources. SAMS-Global calculates the airborne pollutant concentration in an area up to approx. 30 km x 30 km and shows as result isolines of the concentration using a Google™ Earth plug in. Therefore for SAMS-Global an internet access is mandatory. The coupling of SAMS-Global to Google Earth allows a world wide use of SAMS-Global.

During a run SAMS-Global calculates in each case every 3 minutes

  • Concentration distribution at the actual time and the
  • expected concentration distribution one hour in the future

SAMS-Global basic version

SAMS-Global contains of the following modules:

  • Gaussian cloud model based on guideline VDI 3945 sheet 1 (see:
  • Mesoscale diagnostic complex terrain wind field model[1]
  • Release rate model for gases, liquids and liquid gases with pool evaporation
  • Substance and scenario database

[1] Topography and land use data are not included for applications outside of Germany and can be supplemented by us optionally. This is not the subject of the present offer. Without topography and land use data a flat terrain with a homogeneous land cover is assumed for the dispersion calculation.


Extention modules

At the moment the following extention modules are available:

  • Extrapolation of measured meteorological data (10 minutes average of wind speed, wind velocity, turbulence and atmosperic stability) at one or several meteorological stations.

Hardware Requirements

For SAMS-Global no special hardware requirements are necessary. Suitable processors are e.g. Intel® Core i5 or better. Screen size should not be less than 19 inches. Internet access is mandatory.
