5      ==============================      ==============================
6    
7    o pkg/exf ALLOW_RUNOFTEMP
8      - if defined,  river and glacier runoff temperature can be read-in from
9        runoftempfile; runoftempfile needs to have same format as runofffile
10    o pkg/thsice (& pkg/bulk_force):
11      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
12        for energy content of Precip + RunOff & Evap (like with pkg/exf).
13      - change computation domain to always be the interior (without overlap).
14      - fix bug (wrong overlap) when using EXF and stressReduction > 0.
15    o verification/tutorial_global_oce_biogeo:
16      - add preliminary OpenAD setup (still has problems)
17    o model/src:
18      - remove unused (since Aug 2006) S/R SET_WRITE_GLOBAL_PICKUP and its call.
19      - remove unused forcing field "dQdT" and associated parameter "dQdTFile".
20      - move forcing adjustment (balancing surface forcing) in specific S/R
21        where might also be applied exchanges (if needed) to forcing arrays.
22    o pkg/shelfice:
23      - allow to specify the Ice-Shelf mass per unit area (instead of
24        shelficeLoadAnomaly) and do the conversion from one to the other
25      - move loading from file of shelficeLoadAnomaly from SHELFICE_INIT_VARIA
26        to SHELFICE_INIT_FIXED: (a) avoid some TAF recompution issues and
27        (b) will be loaded in time (before calling INI_PRESSURE) in case it is
28        needed in phi0surf for initial pressure calculation when useDynP_inEos_Zc
29      - update isomip experiment forward output (get machine truncation error
30        from conversion shelficeLoadAnomaly -> shelficeMass -> shelficeLoadAnomaly)
31    o verification/offline_exf_seaice:
32      revise data.seaice in input.thermo and input_ad and update results accordingly
33        HO = 0.2, SEAICE_areaLossFormula = 2,
34        SEAICE_growMeltByConv = .TRUE.,
35        SEAICE_doOpenWaterMelt = .TRUE.,
36      Improve consistency with input.thsice and fix the spurious 500m ice corners
37    o verification/global_ocean.cs32x15:
38      - set Energy Reference Level to liq. water @ 0 degC: temp_EvPrRn=0.,
39        in icedyn (thsice+seaice-dyn) test and update output.
40    o verification/offline_exf_seaice:
41      - adjust list of tested variables (with testreport) and update
42        standard test output with better slection of monitored fields.
43    o pkg/cd_code:
44      - swtich off Adams-Bashforth on the 1rst iteration. Update output of
45        experiment lab_sea.hb87
46    o tools/genmake2:
47      - change default makedepend from the system default to tools/xmakedepend:
48        When no makedepend is specified, select tools/xmakedepend it the test pass,
49        otherwise select the system default (if exist and pass the test) or
50        try to build cyrus-makedepend ; stop if none of the 3 works.
51    o pkg/exf & pkg/thsice:
52      - In case Energy-Reference-Level (ERL) is used (temp_EvPrRn=0), account
53        for energy content of Precip + RunOff & Evap. Assumes:
54       1) Rain has same temp as Air.
55       2) Snow has no heat capacity (consistent with seaice & thsice pkgs)
56       3) Run-Off comes at the temp of surface water (with same Cp)
57       4) Evap over ocean is released to the Atmos @ surf-temp (=SST); should be
58        put directly into Latent Heat flux & should use water-vapor heat capacity.
59       5) Evap over snow/seaice (pkg/thsice) assumes constant Lf+Lv (consistent
60        with snow having no Cp) => water vapor is released to Atmos @ 0^oC (=ERL).
61    o pkg/seaice: simplify the use of CPP flags in JFNK-related files
62        (compile when SEAICE_ALLOW_JFNK is defined)
63    o pkg/thsice:
64      - fix oceanic flux diagnostics & timeave (left from new sequence of calls
65        implementation): move THSICE_AVE call after the advection (called directly
66        from thsice_do_advect.F).
67    o verification/global_ocean.90x40x15 and OpenAD:
68      New experiment for OpenAD is identical to the one in input_ad except that
69        multiDimAdvection=.FALSE.,
70      There is still an issue with this.
71    o pkg/thsice:
72      - account for ice velocity (ocean relative velocity) in turbulent heat flux
73        at the base of the ice; update output of global_ocean.cs32x15 (icedyn)
74        and offline_exf_seaice (main test).
75    
76    checkpoint64f (2013/03/31)
77    o verification/OpenAD:
78      - new (smaller, without OAD_DEBUG) output_oadm.txt generated using gfortran.
79    o verification/isomip, pkg/shelfice and OpenAD:
80      - add OpenAD setup to this exp and make shelfice package work with OpenAD
81    o verification/tutorial_global_oce_biogeo:
82      - update AD and TLM output after turning off ALLOW_FE (in DIC_OPTIONS.h)
83    o verification/offline_exf_seaice:
84      - replace adjoint experiment (now similar to fwd input.thermo/ setup).
85    o verification/tutorial_tracer_adjsens, pkg/ptracers and OpenAD:
86      - add OpenAD setup to this exp and make ptracers package work with OpenAD
87    o pkg/seaice/seaice_evp.F:
88       mask the asymmetric contribution of the ice-ocean stress (when
89       the turningAngle is non-zero) over open water to avoid stripes
90       in the EVP-solutions after many EVP-substeps. This does not change
91       the verification experiment (because turningAngle=0 in that experiment),
92       but will affect other EVP solutions with turningAngle.ne.0
93    o verification, AD & TLM output:
94      - new TAF version 2.3.10 (previously 2.3.8) add more parenthesis in multiple
95        additions and multiplications which affect results at machine truncation
96        level. Update few AD output (1D_ocean_ice_column, bottom_ctrl_5x5,
97        lab_sea.noseaicedyn & offline_exf_seaice) and TLM output
98        (1D_ocean_ice_column & tutorial_tracer_adjsens.som81) which had only 12
99        digits of matching.
100    o pkg/seaice:
101       modify lsr-algorithm so that it vectorizes AND converges by using a
102       "zebra" method: split vector loop into two with step size 2; this
103       solves a general convergence problem for the JFNK solver on a vector
104       computer. It has the potential to even improve convergence for
105       non-vector machines, but it does change the results so it is turned
106       off by default. To turn on define CPP-flags SEAICE_VECTORIZE_LSR and
107       SEAICE_VECTORIZE_LSR_ZEBRA in SEAICE_OPTIONS.h
108    
109    checkpoint64e (2013/03/05)
110    o pkg/ecco and several verification experiments:
111       Remove special versions of the_model_main.F, the_main_loop.F, forward_step.F
112       from ecco package, and revert to unified routine in model/src/
113       Adjust verification experiments accordingly, especially gloal_oce_llc90
114       Should conclude long-standing work by Gael to reconsile the_main_loop with
115       ECCO and will enable OpenAD's revolve loop in ECCO setup.
