Wave Perturbation - Global Ionosphere Thermosphere Model (WP-GITM)

Lead architect and developer

WP-GITM is an open-source tsunami/earthquake-ionosphere coupling model. It is an extension of the first-principles model GITM to include atmospheric acoustic-gravity wave forcing generated from impulsive surface disturbances like tsunamis and earthquakes. WP-GITM is available as part of GITM at https://github.com/GITMCode/GITM.
