NB: here is the new name set in revision number 3318 !''' trdtra!''' module Add a systematic mask of the trend. Change the comments to better describe the purpose of this module. Its purpose is: 'TRA' case: to regroup T & S trends and send them to trd_mod, with, in case of advection, transform the incoming advective fluxes into advctive trend (U.grad[T]) 'TRC' case: send trend to ted_mod_trc, with, in case of advection, transform the incoming advective fluxes into advective trend all cases : mask the trend (!''' ===>>> PROBABLY add in the module a lbc_lnk so that the trend is defined everywhere!''' ) !''' dynadv_cen2 and _ubs!''' modules change jpdyn_trd_had into jpdyn_trd_keg.

And obviously suppress jpdyn_trd_dat from trdmod_oce Also suppress the jpdyn_trd_had case horizontal advection for the dynamics is 'keg' + 'vor' ; in case of flux form, 'had' is put in 'keg' and the metric terms is put in 'vor' there is now only 10 trends on the dynamics instead of 12 !''' trdmod!''' module 1- introduce the new logical namelist parameters 2- introduce new subroutines : !'''trd_budget!''' : computation of the domain averaged T,T!^2!^, PE, KE trends formerly computes in trd_mod routine) !''' trd_3Diom!''': output of the 3D trends using IOM !''' trdicp!''' module add in trd_twr routine the computation of the vertical diffusive trend on T & S in case of iso-neutral diffusion (ln_traldf_iso=T). These trends ("ttrd_zdfp", "strd_zdfp") name zdfp for "PURE" vertical diffusion trends are output so that by difference with "zdf" trends we can access to the vertical contribution of the iso-neutral operator !''' iodef.xml!''' file add all the trends nick name : !'''==>>> CAUTION only in the ORCA2_LIM directory!''' ---- === !'''

Suppress trd_icp routine (i.e. trd_2d, trd_3d) as the work is now simply done in trd_budget. 4- rescan all dyn/tra trend indices. add jptra_trd_zdfp for "PURE Kz dissusive trend when ln_traldf_iso=T (see also changes in tranxt where a call to trd_tra is done just before the swap, so that PURE Kz trends can be diagnosed in tra_trd. See also xml file). 5- jptra_trd_nsr and jptra_trd_cdt are 3D trends as their incorporate both surface forcing AND runoff, the later being possibly spread in depth (!'''==>>> probably to be changed!''') 6- suppress the key_trddyn key trdtra from trdicp !''' trdtra - trddyn - trdmod - trdvor!''' modules : impact on !'''

This impact TRA,DYN, TRD but also all TOP_SRC 0- move trdmod_oce into trd_oce 1- trdvor: move the trdvor 1st part from trdmod to trevor module. Suppress the call of trd_vor from step (now called in trddyn for each trend, with the output done for the last trend (_atf). 2- create a trddyn that manage the distribution to iom, global mean, KE, vor, mld 3- trdtra in TRC case pre-process advective trends and then call trdmod_trc ; in TRA case: it regroups T & S trend in one and calla local routine to manage the distribution to iom, global mean, PE, mld 4- trdmod now contains only the trdmod_init routine.

In trdtra.F90: * removed semi-colon on lines 118 and 267. * replaced ln_glo_trd by ln_PE_trd in line 239. * Moved wrk_alloc and wrk_dealloc in the IF (.NOT.lk_vvl ) structure. In trddyn.F90: * Added wrk_alloc, wrk_dealloc and lbc_lnk in trd_dyn_iom. Remove unused variables ztswu, ztswv. * Following norm in the code, utrd_bfr and vtrd_bfr should be filled only when ln_bfrimp=.FALSE. (non implicit bottom friction). * Implicit bottom friction is calculated at the end of each timestep, in dynzdf_imp. The diagnostic of bottom friction in the implicit case is saved in separate variable names to avoid confusion: utrd_bfr_imp and vtrd_bfr_imp. Similarly, diagnostics of wind stress inputs are provided in 2D fields utrd_tau and vtrd_tau. In step.F90: * Added "IF( .NOT.ln_bfrimp)" before the "CALL dyn_bfr( kstp )" to clarify that dyn_bfr is called only if bottom friction is explicit, as proposed by gm. In trdglo.F90: * In trd_glo_init, corrected definition for tvolt: tvolt = tvolt + SUM( e1e2t(:,:) * fse3t(:,:,jk) * tmask(:,:,jk) * tmask_i(:,:) ) * Treatment of bfr has been clarified: if bfr is implicit (ln_bfrimp=.TRUE.), the bottom friction term remain 0, as bottom friction is implicitly included in the vertical diffusion term.
