The Aerodynamic damping parameter has been made available using GitHub. This aerodynamic damping parameter is an essential part to implement the full CICIND vortex shedding calculations. It is also used for the proposed vortex calculation method by G. K. Verboom and H. van Koten https://www.researchgate.net/publication/239352144_Vortex_excitation_Three_design_rules_tested_on_13_industrial_chimneys.
You may find the mentioned aerodynamic damping parameter here: https://github.com/jimmyberg/CICIND-Ka.
Chimney uses the data, which has been made available for this reason. The original data has been given via the organization of CICIND which was derived from the research of R.I. Basu.
