First select the options that you require. Then push to run the model. Click here to down-load the latest postscript image to be created. The Leicester model is a much simplified version of the full IRI code, and hence should run a lot faster. The number of grid points over which the desired variable is computed.
Computation time is independent of the value chosen.
The F2-region propagation factor, inficating signal strength at a range of 3000 km. The altitude of peak electron density. The value of electron density at the peak altitude. The total electron content, a vertical column integral from the surface to infinity. Coloured squares at the resolution over which the grid was calculated.
