48    o Modif's to enable tangent linear run in ECCO environment

70      (still needs checking)
71    
72    ecco_c50_e32
73    o Patrick's adjoint-model storage directives for pkg/seaice
74    o merged with checkpoint50g_post (pkg/seaice and verification/lab_sea)
75      - added SEAICE_MULTILEVEL for 8-category sea-ice thermodynamics
76      - LSR sea-ice dynamic solver moved to SouthWest B-grid location and
77        made the default because of faster convergence than ADI

87    
88    ecco_c50_e31
89    o exf totally restructured
90      - replaced all exf_set_ routines by one generic exf_set_gen.F
91        and made sure it's still differentiable
92      - split exf_getffields.F into new exf_bulkformulae.F
93      - exf_inscal_/exf_outscal_ suffixes consistent with field names
94    o New cost function: Tini-Tfin to do model spinup optimization.

99      #define ALLOW_ATM_WIND && #undef ALLOW_ATM_TEMP
100    o Merging from release1_p13 and from icebear5
101      - bug fix for pkg/seaice dynamic solver

108        Fix for negative intervals shorter than 1 day.
109    
110    ecco_c50_e29
111    Bug fix for merging between c50 and KPP.
112    ikey was passed from thermodynamics to kpp_calc via
113    common block rather than being recomputed in kpp_calc,
114    in contradiction with new key itdkey.
115    New key ikppkey created, and tamc.h headers updated.
116    
117    ecco_c50_e28
118    o major merge:
119      ecco-branch merged with checkpoint50
120      gmredi now available, grdchk, DIVA up-to-date for MPI
121      However, two outstanding problems:
122      - kpp adjoint is broken, needs fixing!
123      - a few minor modif's in handling of CPP option
124        ALLOW_TANGENTLINEAR_RUN in conjunction with
125        ALLOW_ECCO_OPTIMIZATION are necessary to enable
126        TLM runs with ECCO setup
127    
128    ecco_c44_e27
129    o exf:
130      - Enable initialisation of forcing fields to constant
131        (runtime) values.
132      - in exf_getffields.F
133        Reduce i-/j-loop to interior domain, discarding overlaps.
134        That also fixes wrong TAF-key computations for key_1, key_2
135        with bulf formulae.
136      - exf_init.F modify #ifdef for exf_init_evap
137      - exf_getffieldrec.F, ctrl_getrec.F
138        The following INT-usages are not safe:
139          fldsecs  = int(fldsecs/fldperiod)*fldperiod
140          fldcount = int(fldsecs/fldperiod) + 1
141        and were modified.
142      - added repeatPeriod (from MAIN branch)
143    o grdchk: updated and merged
144      - has both ADM and TLM checks
145      - works for single- and multi-proc.
146      - output cleaned
147      - worked successfully for parallel DIVA
148      Needed one update in EEPARAMS.h and updates in ctrl package
149      More modif's may be necessary for ECCO code to support TLM.
150    o autodiff: checkpoint_lev...
151      - updated storing for bulk formulae (some arrays were missing)
152      - added state for seaice package
153      - synchronized with main branch
154    o DIVA:
155      Modif.s in
156      - cost_init.F
157      - cost_averagesfields.F
158      - ecco_the_main_loop.F
159      - ecco_the_model_main.F
160      and added cost_final_restore.F cost_final_store.F
161      o With these changes, it is possible to fully separate
162        the first forward run to compute the cost function (mdthe_main_loop)
163        and adjoint runs over individual DIVA intervals (adthe_main_loop)
164        into separate model executions.
165        This enables better tuning of DIVA to given queue sizes.
166      o Loss of cost function value in consecutive DIVA runs is
167        fixed by storing to 'costfinal' file.
168      o Appropriate call of ctrl_unpack/_pack,grdchk_main at
169        beginning/end of adjoint integration is accounted for.
170      The current changes apply to TAF-1.4.26.
171      TAF has one remaining bug, requiring one manual change
172      (see MITgcm manual).
173    o bug fix plus modif for ubar, vbar in cost_averagesfields
174    o cal: synchronized between MAIN and ecco-branch
175    
176    icebear4
177    o Added cost_ice for sea-ice volume sensitivity experiment.
178    o ecco_the_model_main.F: SEAICE_WRITE_PICKUP must precede WRITE_CHECKPOINT
179    o Reduced derivative singularities in pkg/seaice.
180    o Updated verification/natl_box_adjoint
181    
182    icebear3
183    o Removed spurious iikey and idkey
184    o pkg/exf
185      - bug fix in treatment of downward radiation
186    o pkg/seaice
187      - added initial sea-ice thickness parameter SEAICE_initialHEFF
188    o updated verification/natl_box_adjoint
189    
190    icebear2
191    o Added missing /* */ to CPP comments in pkg/seaice, pkg/exf,
192      kpp_transport_t.F,and ecco_the_main_loop.F
193    o adjoint-friendly modifications to pkg/seaice
194    o added verification/lab_sea as per release1_p12_pre
195    
196    ecco_c44_e26
197    o Merging pkg/exf and pkg/seaice from cvs tag ecco_ice2
198    o exf: Modifications to correctly handle evap field for adjoint
199    o grdchk:
200      Added code to perform gradient checks for bulk formulae/atmos. state
201      (atemp, aqh, uwind, vwind).
202      NOTE:
203      This package is out of synch with c48 package.
204      The latter also has the tangent linear gradient checks.
205      Need to be merged.
206    o verification/natl_box_adjoint:
207      * added new setup: code_bulk/, input_bulk, results_bulk
208        (Experiment 2, described in README)
209        uses bulk formulae and atmos. state as control instead of
210        air-sea fluxes.
211        Performs gradient checks for first 4 elements of atemp control.
212      * changed standard verification to perform
213        gradient checks on first 4 elements on hflux control.
214      * gmredi switched off (will come after merge with c48).
215    
216    ecco_c44_e25

225      - cleaned old exfa stuff
226      - bug fixes

229      - added exf I/O for atmospheric loading
230      - added exf I/O for runoff data
231      - transfered scaling between exf <-> MITgcm to exf namelist

234    o modifications to gradient check package (Martin Losch)
235      - enable centered differences
236      - modified format of standard output
237    o bug fix for nwettile contents
238      so far assumed global sum  in first entry (1,1,k),
239      needed for global control vector
240      -> introduced new variable nwet[c/w/s]global(nr)
241    o shifts of calls to cal/exf package to be accessible
242      in MITgcm stand-alone
243    o shifted packages_init_variables before convective_adjustment_ini
244      (corresponding update of TAF tape initialisation).
245    o removed auxiliary field in impldiff
246      (caused numerical differences for GMRedi cases)
247    o updated obcs control part (G. Gebbie)
248    o removed some f90 comments ("!")
249    o Bug fixes and updates in cost package
250     * cost_final: correct multiplier mult_tauv, mult_sflux

272      monitoring of adjoint state.
273    o Plus: removed comm_stats, ini_communication_patterns from diff. list
274      (no more need to "keep" MPI headers for adjoint generation)
275    o Plus: exf changes:
276      o added run-off routine
277      o additional storing needed for ustress,vstess
278        because of state-dependent quality check
279      o added missing initialisations
280    o Plus: genmake with MAKEDEPEND variable was still missing in ecco-branch
281    NB: - verification/natl_box_adjoint/ 240 steps run
282          * looks ok under Linux (twain.lcs.mit.edu)
283          * looks ok on MIT SUN's (fjord.mit.edu)
284          * NaN in reverse mode on Scripps SUN's at iter=214

288

300      (by G. Gebbie)
301    o missing call to obcs_diags
302    o moved calls in packages_init_fixed to packages_readparms
303      because some quantities are needed earlier.

306    o before major merges from the Scripps setup
307      here are two small updates:
308      - field swapping for surface flux controls enabled

355    o last changes:
356      * assuming path for TAF and TAMC are known (e.g. in $path)
357      * genmake:
358        - added tools/xmakedepend to circumvene shortcoming of
359          SUN's makedepend (size too small)
