The Canadian High Arctic Ionospheric Models (CHAIM)
The Canadian High Arctic Ionospheric Models (CHAIM) is a suite of empirical (E-CHAIM) and assimilation (A-CHAIM and R-CHAIM) ionospheric electron density models designed for application at high latitudes. Funding for CHAIM was provided by the Canadian Natural Science and Engineering Research Council (NSERC) and Defence Research and Development Canada (DRDC), contract number #W7714-186507.

Rules of the Road
When using the Empirical-Canadian High Arctic Ionospheric Model (E-CHAIM) for scientific purposes, we ask users to adhere to the following guidelines:
- List the version number for the version of the E-CHAIM code you are using (ex: v1.4.0).
- While we do not ask to be included as co-authors to your publications using the model, we do ask that you let us know after you have published a paper that uses the model. This goes a long way to helping us justify further funding support to keep the model available and free.
- Please include the following acknowledgement in publications using the model: “E-CHAIM is supported under Defence Research and Development Canada contract number W7714‐186507/001/SS and is maintained by the Canadian High Arctic Ionospheric Network (CHAIN) with operations support from the Canadian Space Agency.”
