MM5 Modeling System Version 3
Version 3 MM5 Change Log
Changes since 3-6:
02/16/04: (Release 3-6-3)
-
Fix a nest initialization problem which occurred if one runs
with 2 nests on the same level AND with the Noah LSM option.
Thanks to Isabelle Delaporte from Earth Observation
-
A fix to the OpenMP directives, which affected only runs with
IFSNOW=2
Thanks to Carlie Coats of Baron Advanced Meteorological Systems
-
A small number of changes to the KF2 scheme. These are mostly
code cleanups to avoid calculations for very small numbers,
which can cause problem on Linux - this is
the only platform we know to have this problem.
Thanks to AJ Deng from PSU and Jack Kain from NSSL.
08/01/03: (Release 3-6-2)
-
Correct MPI feedback of XLAND. Only effect if running with
IEXSI=2
-
Correct a dimension error for XLAND
-
Correct an error for filling outer row and column for GS TKE
-
Fix an "out of bound" problem for TKEA in MPI code
-
Add feedback of SEAICE
-
Initialize seaice on nest from LOWBDY1 if no LOWBDY2 exist.
For iexsi >= 1
-
Add feedback of TGSI
-
Add TGSI to MMOUT_DOMAINx
-
Add a fix to Reisner2
(See comments at top of affected files for more details)
-
Ensure that VEGFRAC is not updated every 24 hours for ISOIL
3 option
-
Improvement in seasonal vegetation adjustment for ISOIL 3
option
-
Soil temp adjustment changed from 6k/km to 6.5k/km, to be
consistent
with rest of programs, effect only if running with old regrid
input
-
Correct print statements to each TBL has separate error information
- Affected file:
domain/initial/param.F
03/04/03: (Release 3-6-1)
1. Bug fixes:
-
Remove line number in the code where #undef is used.
-
Remove tabs to prevent failed compilation on some platforms.
-
Syntax correction to lookup table version of Reisner 1 scheme
- to prevent compilation error. Also update two constants used
in the routine so that it is consistent to the non-lookup table
version of the code.
-
Fix to prevent division by zero in Reisner 2.
-
Define Z0 when there is no snow in Noah LSM.
-
Prevent compilation error on some machines.
-
Correction to Noah LSM for seaice initialization.
-
Include IPOLAR switch in configure.user.linux file.
-
Correct the initialization of the SWDOWN field when the CCM2
radiation is used.
This only affected the MPP version of the code.
2. Changes:
-
Add a new switch, ISFMTHD, in LPARAM to allow for a different
way to diagnose 2 m temperature/moisture and 10 m winds in stable
regime. The general impact in a stable regime would be cooler
temperature and weaker winds.
(Thanks to John Nielsen-Gammon of Texas A&M.)
