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.
