Computes the International Reference Ionosphere (IRI), which is an internationally recognized model for various ionospheric properties.
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 the online interface at http://omniweb.gsfc.nasa.gov/vitmo/iri_vitmo.html using the curl command on an operating system terminal. Because of this, it 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.
An example script for how to use the function is given as iritest.m. This is also the script that generated the attached screenshot. It took a little less than 15 minutes to run on my computer. The mapping toolbox is needed to run this script.
As stated, the query is made using the command curl in an operating system terminal. This program is built-in to Unix (and Mac I believe) but not Windows. Windows users can download cURL from http://curl.haxx.se/download.html. You'll have to download the appropriate executable for your operating system, and I recommend putting it in the same directory as iri.m.
