CCSM/ESMF Stage-2 Release Schedule

• CCSM-ESMF Stage 1 Release schedule

  Milestone 1 – Move to cam3_4_00

• Update csm_share to latest, put on csm_share trunk (DONE) share3_070220
• Update csm_share_emodules branch to share3_070220 DONE (need to add frozen branch tag)
• Make sure csm_share unit tests work. DONE
• Add ability to transfer the following variables to/from an ESMF state: ( NOT DONE)

  CCSMInit%single_column CCSMInit%scmlat CCSMInit%scmlon CCSMInit%logFilePostFix (DONE) CCSMInit%outPathRoot (DONE)

• Update the csm_share unit tests to make sure the above works. (NOT DONE)
• Update clm ESMF branch from clm3_expa_76 to clm3_expa_91. Move changes that occur in lnd_comp_mct.F90 to lnd_comp_esmf.F90. Changes include:timing changes. (Samson) (NOT checked in)
• Update cam from cam3_3_38 to cam3_4_00, use the new clm and csm_share tag created above. Changes include: single phase for atm, timing changes. (NOT checked in)
• Put in redist functionality in map_atmice_esmf.F90 and map_atmocn_esmf.F90 (rather than using explicit copying)
• We think we have everything up to this point – need to have it checked in. It's bit-for-bit with the MCT version (using ESMF time-manager in both cases) only up to time-step 3 when it diverges to roundoff. That indicates one of the surface models has an albedo that diverges to roundoff.
• Test that everything works for cam3_4_00 version (using test_driver.sh script)- must have ESMF and MCT version be bfb for the tests (see BL_ROOT in testing scripts) - need to use ESMF library for time manager in both cases

  Milestone 2 – Move to cam3_5_01

• * NEXT STEPS MUST STILL BE DECIDED*
• Create drv/seq_esmf module with branches, branch_tags, trunk, and trunk_tags directories, create as drv_1_0_1 merge to be equivalent to drv_1_0_10. Move driver to seq_esmf directory.
• Update clm esmf branch from clm3_expa_91 to clm3_5_00, just to make next merge easier. Move changes that occur in lnd_comp_mct.F90 to lnd_comp_esmf.F90
• Update csm_share emodules branch to share3_070321
• Update csm_share emodules branch to cpl709_share3_070410. Add ability to convert the following to/from the ESMF state:

  logical :: dead_comps logical :: lnd_present logical :: ice_present logical :: ocn_present logical :: prog_atm logical :: prog_ocn logical :: userest_atm logical :: userest_lnd logical :: userest_ocn logical :: userest_ice

• Add eshr_estate_sum and eshr_estate_avg methods to csm_share emodules
• Update the csm_share unit tests to make sure the above works.
• Figure out how driver externals will work
• Figure out how the fractional component will work
• Update drv to drvseq1_0_32, add COUP_SOM to mrg_ocn, update domain checking, add dead logic, add rtm component, seq_flds moved-Create fractional component.
• Update clm to clm3_5_03
• cam3_4_14: Update cam esmf branch to seqflxave16_cam3_4_12, new drv module, SVN externals moved up a directory, and ocn called after cam.
• Update csm_share, drv, and clm to latest tags
• Move csm_share to trunk
• Move drv to trunk
• Move clm to trunk
• Move cam to trunk with above tags

  Milestone 3 – Update ESMF components for general Sequential CCSM

• Allow ocn/ice and atm/lnd on different grids
• Create dead ESMF components
• Create d???7 ESMF components
• Create stub components – for CLM
• Get stub option for ESMF working in CLM
• Get dead and d???7 ESMF components working in CLM and CAM
• Update mappers to do regridding
• Update components to do time-averaging
• Update driver to operate at different coupling intervals for ocean
• Turn POP, D???7, CICE into ESMF components
