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
  

  • Affected file:
    domain/nest/initnest.F

• A fix to the OpenMP directives, which affected only runs with IFSNOW=2
  Thanks to Carlie Coats of Baron Advanced Meteorological Systems
  

  • Affected file:
    dynamics/nonhydro/solve.F

• 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.
  

  • Affected files:
    physics/cumulus/kf2/kfpara2.F,
    physics/cumulus/kf2/lutab.F,
    physics/cumulus/kf2/tpmix2.F
    
    

08/01/03: (Release 3-6-2)

• Correct MPI feedback of XLAND. Only effect if running with IEXSI=2

  • Affected file:
    MPP/RSL/parallel_src/mp_feedbk.F

• Correct a dimension error for XLAND

  • Affected file:
    physics/cumulus/bm/cupara7.F

• Correct an error for filling outer row and column for GS TKE

  • Affected file:
    domain/io/outtap.F

• Fix an "out of bound" problem for TKEA in MPI code

  • Affected file:
    MPP/RSL/parallel_src/mp_stotndt.F

• Add feedback of SEAICE

  • Affected files:
    domain/initial/init.F
    domain/boundary/lbdyin.F
    domain/nest/feedbk.F
    MPP/RSL/parallel_src/mp_feedbk.F
    MPP/RSL/parallel_src/define_comms.F

• Initialize seaice on nest from LOWBDY1 if no LOWBDY2 exist. For iexsi >= 1

  • Affected files:
    domain/nest/initnest.F
    MPP/RSL/mpp_initnest_30.incl

• Add feedback of TGSI

  • Affected files:
    domain/nest/feedbk.F
    MPP/RSL/parallel_src/mp_feedbk.F
    MPP/RSL/parallel_src/define_comms.F
    MPP/RSL/parallel_src/bcast_size.F
    MPP/RSL/parallel_src/merge_size.F

• Add TGSI to MMOUT_DOMAINx

  • Affected file:
    domain/io/outtap.F

• Add a fix to Reisner2
  (See comments at top of affected files for more details)

  • Affected files:
    physics/explicit/reisner2/exmoisg.F
    domain/initial/paramr.F

• Ensure that VEGFRAC is not updated every 24 hours for ISOIL 3 option

  • Affected file:
    dynamics/nonhydro/solve.F

• Improvement in seasonal vegetation adjustment for ISOIL 3 option

  • Affected file:
    physics/pbl_sfc/pxpbl/vegeland.F

• 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

  • Affected files:
    domai/io/rdinit.F

• 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.

  • Affected file:
    dynamics/nonhydro/solve.

• Remove tabs to prevent failed compilation on some platforms.

  • Affected files:
    physics/pbl_sfc/noahlsm/surfce.F, slfx.F
    domain/initial/init.F
    domain/nest/feedbk.F

• 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.

  • Affected files:
    domain/initial/param.F
    physics/explicit/reisner1/lexmoisr.F
    physics/explicit/simple/lexmoiss.F

• Fix to prevent division by zero in Reisner 2.

  • Affected file:
    physics/explicit/reisner2/exmoisg.F

• Define Z0 when there is no snow in Noah LSM.

  • Affected file:
    physics/pbl_sfc/noahlsm/sflx.F

• Prevent compilation error on some machines.

  • Affected files:
    domain/initial/init.F
    domain/nest/initnest.F

• Correction to Noah LSM for seaice initialization.

  • Affected file:
    physics/pbl_sfc/noahlsm/surfce.F

• Include IPOLAR switch in configure.user.linux file.

  • Affected file:
    configure.user.linux

• Correct the initialization of the SWDOWN field when the CCM2 radiation is used.
  This only affected the MPP version of the code.

  • Affected file:
    MPP/RSL/Makefile.RSL

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.)

  • Affected files:
    Templates/lparam
    domain/initial/param.F
    physics/pbl_sfc/hirpbl/hirpbl.F
    physics/pbl_sfc/mrfpbl/mrfpbl.F
