Release Notes¶

New validated features in the public release¶

Weimer 2005 electric potential model, optionally with IMF data.
Dynamic critical cross-over latitudes for transition between dynamo and empirical models at high-latitude.
For a more detailed description of the use of the Weimer 2005 model in the TIEGCM, and the dynamic cross-over latitudes, please see Notes on Weimer05 in TIEGCM.
New diagnostics module (diags.F). 22 “sanctioned” diagnostic fields are available, and can be saved on secondary histories (see diags.table in doc directory).
HPSS archive script can be saved by the model, to be executed after a run to save history files to the NCAR HPSS with “contents” annotations.

Make.machine files containing platform and machine-specific compiler and link options, library locations, etc. are available in scripts directory.
New simplified Makefile without platform-dependent conditionals.
Support for Intel ifort/mpif90 compiler on 64-bit HAO Linux systems (Intel-built code is significantly faster than PGI-built code on systems with Intel hardware)
Write svnversion to history files.

tgcm_contents: Print “contents” (annotations) of history files
tgcm_ncdump: Print ncdump of history files, with data for scalars and 1d vectors
tgcm_put: Archive history files on the NCAR HPSS storage system
mknamelist: Make a namelist input file
mkjob: Make a job script

Namelist input files and job scripts for benchmark runs are available in the tests/ directory.
Seasonal steady-state source histories are provided for both equinoxes and solstices, at solar minimum and solar maximum conditions.
The following benchmark runs were made with tiegcm v1.94:
- Control: 5-day Control Runs are made, starting from the steady-state seasonal source histories.
- Climatology: Full-year Climatology with constant solar forcing.
- Dec2006: December, 2006 “AGU” storm case.
- Nov2003: November 19-24 (days 323-328), 2003 storm case.
- Whi2008: Whole Heliosphere Interval (WHI), March 21 to April 16, 2008.
For more detailed information and access to the history files and post-processing, please see Benchmark/test runs.

Weimer potential model with IMF data from IMF_NCFILE, and F10.7 data from GPI_NCFILE.
HPSS_PATH specifies destination path to the NCAR HPSS, for history file archive script. (All references to the old NCAR MSS have been removed)
Time-dependent namelist option for F107a and F107d
The following namelist parameters are deprecated: SAVE, SECSAVE, DISPOSE

All new User’s Guide (pdf, html) is now provided in the doc directory.
Model Description (pdf) also provided in the doc directory.
README.download: Information and instructions for downloading and executing a default run with the current version.
Release_Notes: Release notes for the current version.

Change nmlon to nlonp1 where defining dynpot, line 292 of magfield.F
Change op(k,i) to nop(k,i) in calculation of ion chemistry heating (qic). Line 119 of qjion.F

Changed units of f107d, f107a, ctpoten, and hpower on the histories.
Divide by avogadro’s number instead of multiplying by 1.66e-24 in sub calczg (addiag.F).
