      Notes on tags used in MITgcmUV
      ==============================
- ecco_c44_e20
+ o vertical grid option: allow to put the Interface at the middle between
- o before major merges from the Scripps setup
+cell-centers ; replace delZ in pkg/kpp by drF.
-   here are two small updates:
+ o GM Advective form: Tracers are advected using the residual transport (=
-   - field swapping for surface flux controls enabled
+   Euler+GM-bolus); set param GM_AdvSeparate=T to return to previous form.
-     (remains t.b.d. for atmos. state plus obcs)
-   - bug fix in active_file.F for xz-/yz- routines
+ checkpoint44g_post
-   - added missing xz-/yz- routines to active_file_ad.F
+ o fix surface correction term in multiDimAdvection (affects plume_on_slope
+   results) ; ifdef missing in thermodynamics.F
- ecco_c44_e19
- o merged necessary patches:
+ checkpoint44f_pre,checkpoint44f_post
-   - AD-related changes for GMRedi
+ o added PTRACERS package
-   - fixes i KPP (delZ -> drF)
+   This allows an arbitrary number of passive tracers to be integrated
-   - hook to OBCS songe layer code in external_forcing
+   forward simultaneously with the dynamicaly model.
-   - errorMessageUnit non-zero in eeboot.F
+   + Implemented so far:
-   - included GMREDI, EXACT_CONSERV to natl_box_adjoint verif.
+     - basic forward algorithm (time-stepping, advection, diffusion, convection)
+     - I/O and checkpointing
- ecco_c44_e18
+     - GM/Redi  *but*  using the GM/Redi coefficient of Salt
- o sponge layer code for obcs was missing
+   + Not implemented so far:
-   - added hook in external_forcing.F
+     - KPP
-   - added storing for TAF
+     - OBCS
- o new routine cost_init_barfiles to initialise
+   + No specific example supplied (yet) but global_ocean.90x40x15 has the
-   adjoint fields adtbar, adsbar, adpsbar
+     necessary data.ptracer file. Simply use -enable=ptracers and uncomment
-   (needed in conjunction with corrected ladinit for active I/O)
+     line in data.pkg.
- o cleaned up and corrected order in packages_readparms, ecco_readparms
+   + This package is disabled by default since it increases storage.
- o corrected and simplified weights for obcs controls
-   - weight fields simplified
-   - bug fix in ctrl_pack
+ o testscript: added -cleanup option
-   - no more write of control vector in ctrl_pack
+ o Shap_filt: a) new shap_filt S/R to use no-slip BC with S2 filter
- o i/j index bug fixes in cost_ssh_mean
+              b) enable to filter 2D fields.
- ecco_c44_e17
+ checkpoint44e_pre,post
- o bug fixes in cost package
+ o re-wrote convective adjustment to use pre-calculated weights
-   * wrong identifier for active I/O of monthly mean psbar
+   Affects: model/src/convective_adjustment.F, convective_adjustment_ini.F
-     (cost_averagesfields, cost_ssh) xx_psbar_dummy
+   Adds:    model/src/convective_weights.F, convectively_mixtracer.F
-   * cleaned all identifier for active I/O of monthly fields
+   Original calls to convect() still in place.
-   * wrong ladinit in various cost routines
- o merge with interval (chkpt44c_post - chkpt44d_post)
+ chkpt44d_pre,post
-   * added missing EXCLUDE_MONITOR flags
+ o added missing EXCLUDE_MONITOR flags
-   * changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
+ o changed "e" to "_d" in gmredi_slope_limit, gmredi_slope_psi
-     (incompatible typ in MIN/MAX expressions caused problems
+   (incompatible typ in MIN/MAX expressions caused problems
-     on IBM SP3)
+   on IBM SP3)
-   * in genmake added variable MAKEDEPEND
+ o in genmake added variable MAKEDEPEND
-     plus resetting for case SunOS
+   plus resetting for case SunOS
-     added timer_stats.c routine for IBM SP3
+ o added timer_stats.c routine for IBM SP3
-   * removed variables in dynamics
+ o removed variables in dynamics
+ !!! I forgot to create tag chkpt44d_pre !!!
- ecco_c44_e16
+ !!! But chkpt44d_pre = chkpt44c_post    !!!
- o new ECCO checkpoint, the first since ecco_c43_e15
-   which is branched from MITgcm.
+ o real fresh water flux implemented with non-linear free-surface.
-   All changes were merged in between (see ecco-branch-mod? tags).
- o last changes:
+ chkpt44c_pre,post
-   * assuming path for TAF and TAMC are known (e.g. in $path)
+ o few fix (mask in shap_s2, EmPmR in external_field_load,
-   * genmake:
+   USE_NATURAL_BCS in solve_for_P);
-     - added tools/xmakedepend to circumvene shortcoming of
+ o add arguments myIter & myTime to S/R obcs_calc & solve_for_P
-       SUN's makedepend (size too small)
-     - invoking ../tools/xmakedepend instead of makedepend
+ checkpoint44b_pre/_post
-     - changed compiler flags for case SunOS
+ o merge of relevant stuff from the ecco-branch:
- ecco-branch-mod5
- o mod's to reproduce open boundary run

- o update store directives for OB control
- o added option ALLOW_OBCS_PRESCRIBE

- ecco-branch-mod4
- o this is the second part of changes necessary to reconcile
-   the natl_box_adjoint verification (with and without grdchk).
