Geophysical indices input file for TIE-GCM

A GPI_NCFILE input for the thermosphere-ionosphere-electrodynamics general circulation model (TIE-GCM; Richmond et al., 1992; doi: 10.1029/92GL00401). This file provides Daily F10.7, 81-day centered mean of F10.7, and Kp for the time period 1950-01-01 – 2023-04-28.
