Coleman's 2002 paper is (legitimately) free on line..
Anyone who's looking at antenna pattern models in the vertical and
horizontal planes should take a look at it. A multitude of links are
available to various copies

In the 20 years since he did this work, ionospheric models (and probably
lightning databases) have gotten better.. One could probably create a
tool to run it for any station location (perhaps using VOACAP as a good
starting point for the propagation model)
VOACAP uses a "climatological" ionosphere model and runs a
straightforward propagation model against that - something like Pharlap
is a higher precision model that can ingest a higher quality ionosphere
model and/or data.
