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 – 2023-01-10. <strong>Netcdf file description</strong> &lt;class 'netCDF4._netCDF4.Dataset'&gt; netcdf gpi_1950001_2023010 {<br> dimensions:<br> ndays = 26673 ;<br> nkp = 8 ;<br> variables:<br> int year_day(ndays) ;<br> year_day:long_name = "4-digit year followed by 3-digit day" ;<br> double f107d(ndays) ;<br> f107d:long_name = "Penticton observed daily 10.7 cm solar flux (sfu)" ;<br> double f107a(ndays) ;<br> f107a:long_name = "Penticton 81-day average 10.7 cm solar flux (sfu)" ;<br> double kp(ndays, nkp) ;<br> kp:long_name = "GFZ 3-hourly Kp index" ; // global attributes:<br> :title = "Geophysical indices input file for TIE-GCM" ;<br> :history = "Created: Tue Feb 21 09:56:36 2023" ;<br> :yearday_beg = 1950003 ;<br> :yearday_end = 2023008 ;<br> :author = "Timothy Kodikara (DLR.de)" ;<br> :write_source = "make_tiegcm_gpincfile.py, write_gpi_ncfile.py" ;<br> :Kp_source = "Geomagnetic Observatory Niemegk, GFZ German Research Centre for Geosciences [doi.org/10.5880/Kp.0001]" ;<br> :F107_source = "Observed solar flux provided by the Dominion Radio Astrophysical Observatory and Natural Resources Canada [ftp://ftp.seismo.nrcan.gc.ca/spaceweather/solar_flux/daily_flux_values/fluxtable.txt]" ;<br> :info = "When using this file, please cite the source as https://doi.org/10.5281/zenodo.7660253" ;<br> }
