! ! ROMS/TOMS Standard Input parameters. ! !svn $Id$ !========================================================= Hernan G. Arango === ! Copyright (c) 2002-2016 The ROMS/TOMS Group ! ! Licensed under a MIT/X style license ! ! See License_ROMS.txt ! !============================================================================== ! ! ! Input parameters can be entered in ANY order, provided that the parameter ! ! KEYWORD (usually, upper case) is typed correctly followed by "=" or "==" ! ! symbols. Any comment lines are allowed and must begin with an exclamation ! ! mark (!) in column one. Comments may appear to the right of a parameter ! ! specification to improve documentation. Comments will be ignored during ! ! reading. Blank lines are also allowed and ignored. Continuation lines in ! ! a parameter specification are allowed and must be preceded by a backslash ! ! (\). In some instances, more than one value is required for a parameter. ! ! If fewer values are provided, the last value is assigned for the entire ! ! parameter array. The multiplication symbol (*), without blank spaces in ! ! between, is allowed for a parameter specification. For example, in a two ! ! grids nested application: ! ! ! ! AKT_BAK == 2*1.0d-6 2*5.0d-6 ! m2/s ! ! ! ! indicates that the first two entries of array AKT_BAK, in fortran column- ! ! major order, will have the same value of "1.0d-6" for grid 1, whereas the ! ! next two entries will have the same value of "5.0d-6" for grid 2. ! ! ! ! In multiple levels of nesting and/or multiple connected domains step-ups, ! ! "Ngrids" entries are expected for some of these parameters. In such case, ! ! the order of the entries for a parameter is extremely important. It must ! ! follow the same order (1:Ngrids) as in the state variable declaration. The ! ! USER may follow the above guidelines for specifying his/her values. These ! ! parameters are marked by "==" plural symbol after the KEYWORD. ! ! ! ! Multiple NetCDF files are allowed for input field(s). This is useful when ! ! splitting input data (climatology, boundary, forcing) time records into ! ! several files (say monthly, annual, etc). In this case, each multiple file ! ! entry line needs to be ended by the vertical bar (|) symbol. For example: ! ! ! ! NFFILES == 7 ! number of forcing files ! ! ! ! FRCNAME == my_tides.nc \ ! ! my_lwrad_year1.nc | ! ! my_lwrad_year2.nc \ ! ! my_swrad_year1.nc | ! ! my_swrad_year2.nc \ ! ! my_winds_year1.nc | ! ! my_winds_year2.nc \ ! ! my_Pair_year1.nc | ! ! my_Pair_year2.nc \ ! ! my_Qair_year1.nc | ! ! my_Qair_year2.nc \ ! ! my_Tair_year1.nc | ! ! my_Tair_year2.nc ! ! ! ! Notice that NFFILES is 7 and not 13. There are 7 uniquely different fields ! ! in the file list, we DO NOT count file entries followed by the vertical ! ! bar symbol. This is because multiple file entries are processed in ROMS ! ! with derived type structures. ! ! ! !============================================================================== ! !

Notice that a value is expected ! for each boundary segment per nested grid for each state variable. ! ! Each tracer variable requires [1:4,1:NAT+NPT,Ngrids] values. Otherwise, ! [1:4,1:Ngrids] values are expected for other variables. The boundary ! order is: 1=west, 2=south, 3=east, and 4=north. That is, anticlockwise ! starting at the western boundary. ! ! The keyword is case insensitive and usually has three characters. However, ! it is possible to have compound keywords, if applicable. For example, the ! keyword "RadNud" implies radiation boundary condition with nudging. This ! combination is usually used in active/passive radiation conditions. ! !

However, in ! realistic applications any change to these parameters requires redoing all ! input NetCDF files. ! ! Lm Number of INTERIOR grid RHO-points in the XI-direction for ! each nested grid, [1:Ngrids].

Domain tile partition parameters. !------------------------------------------------------------------------------ ! ! Model tile decomposition parameters for serial and parallel configurations ! which are used to determine tile horizontal range indices (Istr,Iend and ! Jstr,Jend). In some computers, it is advantageous to have tile partitions ! in serial applications. ! ! NtileI Number of domain partitions in the I-direction (XI-coordinate). ! It must be equal to or greater than one. ! ! NtileJ Number of domain partitions in the J-direction (ETA-coordinate). ! It must be equal to or greater than one. ! !

Lateral boundary conditions parameters. !------------------------------------------------------------------------------ ! ! The lateral boundary conditions are now specified with logical switches ! instead of CPP flags to allow nested grid configurations. Their values are ! loaded into structured array: ! ! LBC(1:4, nLBCvar, Ngrids) ! ! where 1:4 are the number of boundary edges, nLBCvar are the number of LBC ! state variables, and Ngrids is the number of nested grids. For Example, to ! apply gradient boundary conditions we use: ! ! LBC(iwest, isFsur, ng) % gradient ! LBC(ieast, ... , ng) % gradient ! LBC(isouth, ... , ng) % gradient ! LBC(inorth, ... , ng) % gradient ! ! The lateral boundary conditions are entered with a keyword. This keyword ! is case insensitive and usually has three characters.

Lateral open boundary edge volume conservation switch for nonlinear model ! and adjoint-based algorithm. Usually activated with radiation boundary ! conditions to enforce global mass conservation.

Time-Stepping parameters. !------------------------------------------------------------------------------ ! ! NTIMES Total number time-steps in current run. If 3D configuration, ! NTIMES is the total of baroclinic time-steps. If only 2D ! configuration, NTIMES is the total of barotropic time-steps. ! ! DT Time-Step size in seconds. If 3D configuration, DT is the ! size of the baroclinic time-step. If only 2D configuration, ! DT is the size of the barotropic time-step. ! ! NDTFAST Number of barotropic time-steps between each baroclinic time ! step. If only 2D configuration, NDTFAST should be unity since ! there is no need to split time-stepping. ! !------------------------------------------------------------------------------ ! Model iteration loops parameters. !------------------------------------------------------------------------------ ! ! ERstr Starting ensemble run (perturbation or iteration) number. ! ! ERend Ending ensemble run (perturbation or iteration) number. ! ! Nouter Maximum number of 4DVAR outer loop iterations. ! ! Ninner Maximum number of 4DVAR inner loop iterations. ! ! Nintervals Number of time interval divisions for Stochastic Optimals ! computations. It must be a multiple of NTIMES. The tangent ! linear model (TLM) and the adjoint model (ADM) are integrated ! forward and backward at different intervals.

In the first iteration (1), the TLM is integrated forward from ! 1 to NTIMES and the ADM is integrated backward from NTIMES to 1. ! In the second iteration (2), the TLM is integrated forward from ! NTIMES/3 to NTIMES and the ADM is integrated backward from ! NTIMES to NTIMES/3. And so on. ! !------------------------------------------------------------------------------ ! Eigenproblem parameters. !------------------------------------------------------------------------------ ! ! NEV Number of eigenvalues to compute for the Lanczos/Arnoldi ! problem. Notice that the model memory requirement increases ! substantially as NEV increases. The GST requires NEV+1 ! copies of the model state vector. The memory requirements ! are decreased in distributed-memory applications. ! ! NCV Number of eigenvectors to compute for the Lanczos/Arnoldi ! problem. NCV must be greater than NEV. ! ! At present, there is no a-priori analysis to guide the selection of NCV ! relative to NEV. The only formal requirement is that NCV > NEV. However ! in optimal perturbations, it is recommended to have NCV greater than or ! equal to 2*NEV. In Finite Time Eigenmodes (FTE) and Adjoint Finite Time ! Eigenmodes (AFTE) the requirement is to have NCV greater than or equal to ! 2*NEV+1. ! ! The efficiency of calculations depends critically on the combination of ! NEV and NCV. If NEV is large (greater than 10 say), you can use NCV=2*NEV+1 ! but for NEV small (less than 6) it will be inefficient to use NCV=2*NEV+1. ! In complicated applications, you can start with NEV=2 and NCV=10. Otherwise, ! it will iterate for a very long time. ! !------------------------------------------------------------------------------ ! Input/Output parameters. !------------------------------------------------------------------------------ ! ! NRREC Switch to indicate re-start from a previous solution. Use ! NRREC=0 for new solutions. In a re-start solution, NRREC ! is the time index of the re-start NetCDF file assigned for ! initialization. If NRREC is negative (say NRREC=-1), the ! model will re-start from the most recent time record. That ! is, the initialization record is assigned internally. ! Notice that it is also possible to re-start from a history ! or time-averaged NetCDF file. If a history file is used ! for re-start, it must contains all the necessary primitive ! variables at all levels. ! ! LcycleRST Logical switch (T/F) used to recycle time records in output ! re-start file. If TRUE, only the latest two re-start time ! records are maintained.

NDEFADJ Number of time-steps between the creation of new adjoint file. ! If NDEFADJ=0, the model will only process one adjoint file. ! This feature is useful for long simulations when output NetCDF ! files get too large; it creates a new file every NDEFADJ ! time-steps. ! ! NSFF Number of time-steps between 4DVAR adjustment of surface forcing ! fluxes. In strong constraint 4DVAR, it is possible to adjust ! surface forcing at other time intervals in addition to initial ! time. This parameter is used to store the appropriate number ! of surface forcing records in the output history NetCDF files: ! 1+NTIMES/NSFF records. NSFF must be a factor of NTIMES or ! greater than NTIMES. If NSFF > NTIMES, only one record is ! stored in the NetCDF files and the adjustment is for constant ! forcing with constant correction. This parameter is only ! relevant in 4DVAR when activating either ADJUST_STFLUX or ! ADJUST_WSTRESS. ! ! NOBC Number of time-steps between 4DVAR adjustment of open boundary ! fields. In strong constraint 4DVAR, it is possible to adjust ! open boundaries at other time intervals in addition to initial ! time.
