MM5 Version 2 Release 2-6 (October 10 1997)
Dear MM5 (V2) users,
This email is regarding the MM5 V2 model's newest release: release-2-6.
This release comprises of a few bug fixes, modified mm5.deck for
an easier input file specification on both Cray and workstations,
and a new switch for using potential temperature advection in temperature
equation, among other changes. The detailed changes are described
in the CHANGES file in the top directory of the new tar file.
The new tar file can be obtained from several locations, including
NCAR's MSS and anonymous ftp.
The CHANGES file separates changes into bug fixes/modification (which
you definitely want to include in your files), new features and
changes (for which you can make a decision as whether you include
them in your copy of the code). In addition to this description,
the actual changes are provided in a diff file: diff.10OCT97, in
directory ReleaseNotes/.
A user should have enough information from these two files to make
corresponding changes to your own files. Most changes in this diff
file are for decks.
If you don't want to get a new tar file, files CHANGES, and diff.10OCT97
can be found from anonymous ftp under /mesouser/MM5V2/MM5, and on
paiute/ouray under ~mesouser/MM5V2/MM5. They are also accessible
from the Web site:
http://www2.mmm.ucar.edu/mm5/mm5v2-changes-r2-6.html
*** Note: IF YOU HAVE NOT MADE ANY CHANGES TO YOUR TAR FILE (including
file structure and source code), YOU SHOULD SAVE YOUR configure.user
FILE and/or mm5.deck, and GET A NEW TAR FILE. Please be aware that
there are changes
in the deck in this release (e.g. new switches).
If you use NCAR's Cray, the default tar file you get from MSS will
be changed to release-2-6 as of this evening, October 10 1997.
If you would like to use any previous releases, you can change the
MSS read statement from
msread mm5v2.tar /MESOUSER/MM5V2/MM5/MM5V2.TAR
to
msread mm5v2.tar /MESOUSER/MM5V2/MM5/MM5V2.TAR.release-2-5-1
and so on.
CVS versions of all MM5 V2 releases (release 2-0 through 2-6) are
currently available from NCAR/SCD's meeker (meeker.ucar.edu).
Information on how to make use it can be obtained from the Web page:
http://www2.mmm.ucar.edu/mm5/cvs.html
This provides users with a way to automatically update your code
with our release if users choose to use CVS.
