Dear Colleague -
You are receiving this email because you are on the tgcmgroup mailing
list. If you do not wish to receive this or other related emails,
remove yourself from the mailing list at:
http://mailman.ucar.edu/mailman/listinfo/tgcmgroup.
The Thermosphere Ionosphere Electrodynamics General Circulation Model
(TIE-GCM) and its predecessors and successors were developed by Ray
Roble and colleagues at NCAR over the past several decades. Last
summer we released TIE-GCM v. 1.9 as a
"community-model-with-a-lower-case-c." at:
http://www.hao.ucar.edu/modeling/tgcm.
"community-model-with-a-lower-case-c" means that scientific
colleagues can use the model, its source codes, and associated
scripts and input files, with some limitations, under the auspices of
an "academic research license" which is described at:
http://www.hao.ucar.edu/modeling/tgcm/download/files/tiegcmlicense.txt.
We are asking people to register, so that we can keep track, and send
them email, but not very often. We are also asking that people
wishing to use the model keep us posted on what they are doing,
collaborate, cite, and in general observe the "rules-of-the-road"
suggested by the CEDAR program, TIMED mission, and similar traditions.
"community-model-with-a-lower-case-c" also means that we can only
offer minimal support, particularly if you are attempting to install
the model on your own computer. But we will try to help as best we
can if you have problems, or wish to discuss scientific issues
related to the model.
The purpose of this email is to announce the availability of TIE-GCM
v. 1.92, which has several updates, bugfixes, and improvements, as
described in the release notes at:
http://www.hao.ucar.edu/modeling/tgcm/release_notes.php.
The most important changes are that the auroral precipitation oval
used when running the Weimer '05 potential/convection model is
improved and ready for "beta testers" or "friendly users," and that
this version contains InterComm links that facilitate coupling to the
Lyon-Fedder-Mobarry magnetosphere model. In this coupled mode, we
refer to the model as the Coupled Magnetosphere Ionosphere
Thermosphere (CMIT) model. CMIT 2.5 is still undergoing testing, but
we hope that it will soon be available for runs-on-request at the
Community Coordinated Modeling Center (CCMC). TIE-GCM 1.92 will also
be available at CCMC in stand-alone mode, which should meet the needs
of many of you.
There is a decent Users Guide and a Documentation file. The latter
is incomplete but we are working on it. Volunteers welcome!
Feedback is also welcome, and those wishing to participate in model
development in a more formal manner (if you aren't already) should
get in touch and join our on-line development group. We are trying
to expand our support capability as resources permit.
Thanks,
Stan,
