Formats of input-output files are commented within the program. It computes electron density-height profiles, electron temperature profiles, ion temperature profiles, neutral temperature profiles and total electron content through the ionosphere and plasmasphere for specified date and location: latitude, longitude (geodetic or geomagnetic), year, month, day, and hour (LT or UT). Adjustment of Ne(h) profile, foF2, hmF2 and the topside scale height to TEC is included if TEC is entered as input parameter. IRIS2017c.FOR This is main subroutine based on IRI main subroutine: http://nssdc.gsfc.nasa.gov/space/model/ionos/iri.html modified to include calls for SMI plasmasphere electron density extension, Te-Ti-Tn-2006-model by J. Titheridge and correction of topside IRI electron density profile based on empirical ISIS-1,2 / IK19 topside half thickness model. It requires the subroutine files listed below.
