Immission Maps & NIR

Data and maps on air pollution

The dispersion model PolluMap

Meteotest, in collaboration with the company INFRAS, has developed PolluMap. It is utilised for particulates, nitrogen dioxide, benzene, BC and sulfur dioxide. On the basis of emission balances, emission cadastres are calculated as a first step. Using transfer functions based on regional climatologies the emissions are converted to immissions.

Our expertise in GIS ensures delivery of the results as clearly presented maps. PolluMap maps are important input maps for the modeling of hourly hybrid maps for pollutant concentrations. PolluMap can be utilised worldwide.

Near-real-time maps of current air pollution

A cartographic representation of the air pollution allows a quick overview of the impact situation and its spatial distribution. With today's density of measuring stations of Swiss cities, cantons and national authorities, it is possible to interpolate realistic maps from the measured data.

The near-real-time hourly maps and annual maps deliver the required information base for environmental authorities. The regional differentiation of air pollution and areas with exceeded thresholds are shown.

Web platforms bring measurements to the Internet

We create web applications which represent the current air pollution situation in tabular and graphical form.

We publish current air pollution concentration maps in dynamic online maps. Using the PolluMap's base maps and interpolation methods, up-to-date maps are calculated.

Meteotest has created, and manages, the following web applications for the public authorities:

NIS calculations with NISMap

NISMap is a software for the calculation of the immissions of high-frequency non-ionizing radiation (NIR).

  • NISMap calculates the electric field strength and the immission of transmitters
  • NISMap manages the data of the systems (antennas, buildings, locations, etc.) in a database
  • NISMap shows the results interactively on the map
  • NISMap produces maps of field strength or immission
  • NISMap creates location data sheets formatted as a Word document in accordance with the FOEN guidelines.

The basic version is used to calculate immission forecasts and create location data sheets in accordance with the requirements of the Federal Office for the Environment (FOEN). In addition to the basic version, there is also an extended version of NISMap. The extended version offers additional dispersion algorithms and options for calculating exposure maps for larger areas.
