=============================================================== Originator: schramm ( Julie Schramm) Date: Mon May 16 15:04:39 MDT 2001 Model: CSIM Version: CSIM4.4.1 One-line summary: Prescribed ice model included, FPE errors fixed, history and restart files can be written to MSS. Changes made: The following modifications were make to these files in csim4_4_1: ice.setup.csh Added namelist options to write history and restart files to MSS. Mods for presribed ice case. ice.F Added timing calls Mods for prescribed ice. ice_coupling.F Receives info_dbug flag from coupler to write global sums. Mods to adjust initial date for prescribed ice case. ice_history.F Uninitialized variables were being referenced by processors other than master_task, 7 occurrences in this file. Added iostat to namelist read statements. Added namelist options to write history and restart files to MSS. ice_init.F Fixed bounds problems with Tsfcn(i,j,nc)=Tf(i,j) Added iostat to namelist read statements. Added namelist options to write history and restart files to MSS. Set namelist variables to agreed upon default values. Added namelist parameters for presribed ice case. ice_itd_linear.F Initialized hL and hR to 0. ice_mechred.F Fixed bug in ice dynamics. ice_mpi_internal.F Added MPI_barrier call to allow model to run on 16 processor s. ice_prescribed.F New file containing prescribed ice module. ice_timers.F Added timing calls. ice_transport.F Fixed bounds problems with Tsfcn(i,j,nc)=Tf(i,j) =============================================================== =============================================================== Originator: schramm ( Julie Schramm) Date: Wed Mar 28 14:40:11 MST 2001 Model: CSIM Version: CSIM4.4.0 One-line summary: Cleaned up mixed layer model, added C. Bitz's bug fixes and new SW physics. Changes made: This version of CSIM4 includes Elizabeth's cleaned up version of the ocean mixed layer model. Cecilia's bug fixes have been added as well as a wavelength dependent io. A flag has been added to receive a write history file command from the coupler, although this feature hasn't yet been implemented. A problem with no restart file being written on the last time step has been resolved. The script files have been updated to be similar to those used by CCSM. The build files are now those used by CCSM. These last two changes have resulted in several changes in the directory structure. This version of the model has not undergone extensive testing. =============================================================== =============================================================== Originator: schramm ( Julie Schramm) Date: Fri Feb 23 14:21:01 MST 2001 Model: CSIM Version: CSIM4.3.0 One-line summary: Contains Elizabeth's and Marika's bug fixes Changes made: This version of the ice model includes all of Elizabeth Hunke's bug fixes, and Marika Holland's changes to the heat budget and exact restart capability. The model is capable of receiving a write_restart command from the coupler. Changes have been make to the share code by Tony Craig. Bruce Breigleb has included an ice thermo-only option and an ocean mixed layer model. The model has been run for 10 days on the gx1v2 grid. =============================================================== =============================================================== Originator: schramm ( Julie Schramm) Date: Tue Jan 16 14:21:37 MST 2001 Model: CSIM Version: CSIM4.2.0 One-line summary: This version contains a new coupler interface and new dummy models. Changes made: These files have been modified to accommodate changes in the ice model and the dummy models. The ice model now passes calculated grid cell areas to the coupler. The coupler sends individual fluxes to the dummy ocean model instead of a net flux. Bruce's changes to the dummy atm model (rain -> snow conversion and a SW factor) are now incorporated into the new version of datm5. This version of the active only ice model, as checked out, will run with docn5 instead of the mixed layer model, since in it's current state, the mixed layer model is not compatible with the new dummy ocean. Due to time constraints with CCSM and the novelty of the cleaned up ice code, this version of the ice model has undergone minimal testing. =============================================================== =============================================================== Originator: schramm ( SCHRAMM JULIE NONE CGD) Date: Fri Dec 22 10:53:35 MST 2000 Model: CSIM Version: CSIM4.1.0 One-line summary: csim4_1_0 is the preliminary cleaned-up version of the ice model. It has been checked out and run on the IBM, and will restart from a restart file. Changes made: Elizabeth Hunke has cleaned up the ice model source code and has converted it to F90 modules. The option to use Bill Lipscomb's linear remapping scheme is included in the code, but has not yet been tested. Bug fixes will be included in the next release. 'Dud' model has been included in ice_coupling.F. =============================================================== =============================================================== Originator: schramm ( Julie Schramm) Date: Thu Nov 9 15:43:04 MST 2000 Model: CSIM Version: CSIM4.0.1 One-line summary: This version of csim4 allows for the 'dud' model, a fake CPU consumer. Changes made: Put case ('dud') lines in coupling.F to allow for the 'dud' model, which is a fake CPU consumer. =============================================================== =============================================================== Originator: schramm ( Julie Schramm) Date: Fri Oct 20 15:18:09 MDT 2000 Model: CSIM Version: CSIM4.0.0 One-line summary: Initial version (pre-cleaned up version) Changes made: Initial version of the ice model, which is an aggregate of code from LANL, NCAR and U-Wash. =============================================================== ===============================================================
