It is the international standard empirical model for the terrestrial ionosphere since Contradictions between these had to be resolved in critical discussions. After a decade filled with data collection, a first set of tables was given out in In , the code became available on floppy disk , and later on the Web.

International Reference Ionosphere (IRI) Model - File Exchange - MATLAB Central
Skip Navigation press 2. Search NASA: These organizations formed a Working Group members list in the late sixties to produce an empirical standard model of the ionosphere, based on all available data sources charter. Several steadily improved editions of the model have been released. For given location, time and date, IRI provides monthly averages of the electron density, electron temperature, ion temperature, and ion composition in the altitude range from 50 km to km. Additionally parameters given by IRI include the Total Electron Content TEC; a user can select the starting and ending height of the integral , the occurrence probability for Spread-F and also the F1-region, and the equatorial vertical ion drift. The major data sources are the worldwide network of ionosondes, the powerful incoherent scatter radars Jicamarca, Arecibo, Millstone Hill, Malvern, St.
IRI - International Reference Ionosphere
Updated 06 Oct Computes the International Reference Ionosphere IRI , which is an internationally recognized model for various ionospheric properties. I would call it more of a hack than a true IRI implementation as it works by querying an online interface using the curl command on an operating system terminal. Because of this, it requires an internet connection and is pretty slow, but if high speed is not an important issue for you, this can be an easy way to get IRI data into MATLAB.
The major data sources are the worldwide network of ionosondes, the powerful incoherent scatter radars Jicamarca, Arecibo, Millstone Hill, Malvern, St. Santin , the ISIS and Alouette topside sounders, and in situ instruments flown on many satellites and rockets. More information can be found in the workshop reports. An IRI listserver keeps the community informed about model updates, workshops, publication, and other IRI-related matters.
