Short summary
The Next-generation Ionospheric Model for Operations (NIMO) is a space weather model developed to provide historic, current, and forecasted information about the density of the ionosphere. This article discusses how NIMO is configured, demonstrates potential use cases for the research community, and validates historic runs using a new suite of metrics designed to allow repeatable, quantitative, model-independent evaluations against observations that may be adopted by other ionospheric models.
