IRI in Windows environment Original Research Article

The International Reference Ionosphere (IRI) is a widely used model recommended for international use by URSI and COSPAR. An interface to Windows has been developed and the stand-alone IRI program is executable on PC systems using Windows 95/98 or Windows NT as the platform. This IRI-Windows version allows computation and plotting of any of the IRI parameters as function of any one or two variables: height, latitude, longitude, UT or LT time, and solar activity. The user can conveniently specify the variables and various options of the model. This paper gives a brief description of the program features and the operating procedure.
