MM5 Version 2 Release 2-7 (December 22 1997)
Dear MM5 (V2) users,
This email is regarding the MM5 V2 model's newest release: release-2-7.
The highlights of this release include:
-
Parallel directives for HP SPP2000 machine;
-
A rewritten sound.F routine, which enables a speedup of 8 -
10 % in a typical run;
-
New output fields, including atmospheric radiative tendency,
surface heat and moisture fluxes, etc.; and
-
bug fixes for MRF PBL (IBLTYP=5), Goddard microphysics scheme
(IMPHYS=6), and Reisner scheme (IMPHYS=7).
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.
A new Graph will soon to be released to enable users to look at
the new output fields.
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.22DEC97, in
directory ReleaseNotes/.
A user should have enough information from these two files to make
corresponding changes to your own files.
If you don't want to get a new tar file, files CHANGES, and diff.22DEC97
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-r2-7.html
*** Note: IF YOU HAVE NOT MADE ANY CHANGES TO YOUR TAR FILE (including
file structure and source code), YOU SHOULD GET A NEW TAR FILE.
If you use NCAR's Cray, the default tar file you get from MSS will
be changed to release-2-7 as of this evening, December 22 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-2-6
and so on.
CVS versions of previous MM5 V2 releases (release 2-0 through 2-6)
are currently available from NCAR/SCD's meeker (meeker.ucar.edu).
The new release-2-7 will be available in the next few days.
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.
