Release Notes for TIEGCM v1.94
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.
- 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.
New Build System (scripts/ directory):
- 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.
Utilities (scripts/ directory):
- 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
Validation and Benchmark Runs (tests/ directory):
- 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 1-6 (days 305-310), 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.
Changes in the documentation directory doc/:
- 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.
Bug Fixes:
- 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
Other:
- 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).
