IRI-90

IRI-90 is an international reference ionosphere model in Python providing monthly mean ionospheric parameters from 50km to 2000km altitude.

IRI-90 from Python, clean and flexible ionospheric model. IRI-90 provides monthly mean values for magnetically quiet conditions at non-auroral latitudes in the altitude range 50km to 2000km. However, IRI-90 is often used as an initialization for conditions at auroral latitudes, understanding the caveats. This IRI-90 Python module is as small and clean as possible to enable custom IRI-90 applications. The module outputs electron density, neutral temperature, ion temperature, electron temperature, and ion composition (O+, H+, He+, O2+, NO+) as an xarray.DataArray indexable by species, altitude, etc. and includes metadata.
