EW LAPMOD reads the CALMET output file(s) prepared by the user or purchased from Enviroware for a domain in any part of the world.

Simulation entities like sources or discrete receptors may be placed manually, by specifying their coordinates, or graphically by clicking over their positions. When all the input data have been specified, the system checks their correctness and prepares the LAPMOD input files. At the end of the LAPMOD simulation, the concentration time trends at the discrete receptors may be plotted and saved. It is also possible to post process the binary output file of LAPMOD to extract the statistics of interest for specific pollutants (e.g., annual average, percentiles, running averages).


Here is a list of some features:

  • Helps inserting and checking LAPMOD input data
  • Allows to specify sources with constant rates, regular time trends and arbitrary time trends
  • Automatically merges all the sources in a unique emission file
  • Meteorological data at any point can be extracted from CALMET and visualized
  • Concentrations at discrete receptors may be plotted soon after the simulation
  • Postprocessing to get the desired statistics is very easy
  • Concentrations can be visualized over the embedded base map

You can download and evaluate EW_LAPMOD for free. A PDF manual will be installed together with the software (use the Help menu item to view it).

A zip file containing meteorological data for two months to test the software is also available.
