Benchmark results (pdf plot files) for version tiegcm2.0 are available here: Post-processing of TIEGCM benchmarks
Benchmark runs are provided in three groups: full-year climatology, seasonal, and solar storm events. Here is a table of runs at 2.5-degree model resolution (there is also a set at the 5-degree resolution):
Full-year climatologies (solar min,max):
tiegcm_res2.5_climatology_smax Full-year climatology at solar maximum conditions
tiegcm_res2.5_climatology_smin Full-year climatology at solar minimum conditions
Seasons (Equinox, Solstice, solar min,max):
tiegcm_res2.5_decsol_smax December Solstice, solar maximum (days 355-360)
tiegcm_res2.5_decsol_smin December Solstice, solar minimum (days 355-360)
tiegcm_res2.5_junsol_smax June Solstice, solar maximum (days 172-177)
tiegcm_res2.5_junsol_smin June Solstice, solar minimum (days 172-177)
tiegcm_res2.5_mareqx_smax March Equinox, solar maximum (days 80-85)
tiegcm_res2.5_mareqx_smin March Equinox, solar minimum (days 80-85)
tiegcm_res2.5_sepeqx_smax September Equinox, solar maximum (days 264-269)

tiegcm_res2.5_nov2003_weimer_imf November 2003 storm, Weimer/IMF,GPI (days 323-328)
tiegcm_res2.5_whi2008_heelis_gpi Whole Helio Interval 2008 Heelis/GPI (days 81-106)
tiegcm_res2.5_whi2008_weimer_imf Whole Helio Interval 2008 Weimer/IMF,GPI (days 81-106)
Note
Climatology and Seasonal runs were made with constant solar conditions as follows:
Solar Minimum Conditions:
Solar Maximum Conditions:
Note
Explanation of terms for Storm Case Benchmarks:
- Heelis: The Heelis Potential Model was used for high-latitude ion drift velocities
- Weimer: The Weimer Potential Model was used for high-latitude ion drift velocities
- GPI: Runs used GeoPhysical Indices data with Kp, and solar flux f10.7d, f10.7a
- IMF: Runs used IMF/OMNI data with Solar Wind density and velocity

Benchmark results (pdf plot files) for version tiegcm2.0 are available here: Post-processing of TIEGCM benchmarks
Results of the benchmark runs are available in 2d plots of time series, grid slices, and maps. These are multi-page PDF files, arranged as follows:
- Files with “singleut” in their names contain instantaneous maps and slices
- Files with “utvert” in their names contain ut vs pressure plots (daily or hourly histories)
- Files with “utlat” in their names contain ut vs latitude plots (daily or hourly histories)

At 2.5-degree model resolution:

These are the namelist input files used for making the 2.5-degree resolution benchmark runs. Note that a few of the 2.5-deg runs need to be run at a shorter timestep than the default of 30 seconds to maintain numerical stability. Also note that the 5-degree full-year climatology run can be completed on yellowstone in 12 hours WC, but the 2.5-deg model has to be restarted several times to reach a full year.
Model output history files are stored in CF-compliant netCDF format. Benchmark history files for tiegcm2.0 are available via the Globus Research Data Sharing Service. The history files are stored at the “NCAR Data Sharing Service” Globus shared endpoint. (for users with an NCAR/CISL login: this endpoint is /glade/u/datashare/tgcm)
See these CISL docs for information regarding the NCAR Data Sharing Service:
- NCAR Data Sharing Service
- Globus file transfers (see especially “Transferring files with the webh interface”)
- Retreiving data from a shared endpoint
Here is a summary procedure for accessing the tiegcm2.0 benchmark data:
Note
You do NOT need to have an NCAR user account or token to retrieve this data.

In each of the 6 benchmark groups are folders for each run, with folders containing the history files (hist), post-processing (proc), and scripts and log files (stdout). Individual files or whole directories can be downloaded.
