• 0: no climatology (default value).
• 1: orography and land-sea mask of output only. In your script, the local name of this external climatology file should be "const.clim.DDDDDDD", where DDDDDDD is the variable CFPDOM of the namelist NAMFPC. This file should be of the same geometry as the post-processing file you want to make.
• 2: all available climatological fields of the current month. Use of auxiliary land-sea mask, orography, surface temperature, relative surface wetness, deep soil temperature, relative deep soil wetness, albedo, emissivity, standard deviation of orography, percentage of vegetation, roughness length, anisotropy coefficient of topography, direction of the main axis of topography and snow depth. For that you need to make 2 climatology files: the first one, named "Const.Clim", should be in the input model geometry, the second one, named "const.clim.DDDDDDD", where DDDDDDD is the variable CFPDOM of the namelist NAMFPC, should be in the output (post-processing) geometry.
• 3: shifting mean from the climatological fields of the current month to the ones of the closest month.
• NDOMFP: domain definition of fields in files; NDOMFP = 1: physical fields are grid-points stored on (C+I)+E and dynamical fields are spectral (option available in ALADIN only); NDOMFP = -1: physical and dynamical fields are grid-points stored on (C+I)+E; NDOMFP = 0: physical and dynamical fields are grid-points stored on (C+I). C, I, E mean respectively conservation domain, intermediate zone and extension zone. Default value depends on configuration:
• if CFPFMT='MODEL', LFPSPEC=.F., default value is -1.
• if CFPFMT='GAUSS','LELAM' or 'LALON' and LFPSPEC=.F., default value is 0.
• if CFPFMT='GAUSS' or 'LELAM' and LFPSPEC=.T., default value is -1 for the first part, 1 for the second part.
• LFPQ: .T. if specific humidity is interpolated (then deduct relative humidity), .F. if relative humidity is interpolated (then deduct specific humidity). Default value is .FALSE. . It is better to use the default value (.FALSE.): in this case, relative humidity is conserved within displacement of the planetary boundary layer and it is interpolated vertically. Relative humidity is considered to have better properties for an interpolation than mixing ratio even if it is not a conservative quantity.
• LASQ: .T. if apparent surface humidity is set to 80% saturation (default value is .FALSE.).
• WSXI: maximum surface moisture in input.
• WDXI: maximum deep soil moisture in input.

• LSNOWO: snow in the output file. Default value is equal to LNEIGE.
• FPBL: critical thickness of PBL. Default value is 17500 Pa.
• RFPCORR: critical orography difference for correcting surface temperature through standard profile, in J/kg. Default value is 300*g.
• RFPMXZ: non-critical maximum difference between interpolated orography and output orography, in J/kg. Default value is 3000*g.
• LFPSPLIT: .TRUE. if split of FULL-POS post-processing of dynamical fields.
• NFPSPLIT: number of dynamical fields to be post-processed at a time.
• MFP3DYN : maximum number of 3D-dynamical fields needed for LFPART2.
• MFP2DYN : maximum number of 2D-dynamical fields needed for LFPART2.
• NFPTRSPLIT: pointer to actual post-processing package of dynamical fields.

Remarks.

• Note that if you ask for post-processing of dynamical fields which are not spectral in the model, then these post-processed fields will not be spectrally fitted, even if the corresponding switch LFIT... is .TRUE. .
• Note that if you wish to post-process upper air dynamical fields on height levels or hybrid levels, it is not possible to apply such spectral fit because the horizontal interpolations are performed before the vertical interpolation in order to respect the displacement of the planetary boundary layer.

For all kinds of output (sub)domains:

• NLAT: number of latitudes for each output (sub)domain (poles not included if a Gaussian grid is required); array of integers; corresponds to the variable NDGLG of the output grid(s) (DM-global).
• NLON: number of longitudes for each output (sub)domain; array of integers; corresponds to the variable NDLON of the output grid(s) (DM-global).
• RLATN: northern latitude in degrees for each output (sub)domain; array of reals (DM-global).
• RLATS: southern latitude in degrees for each output (sub)domain; array of reals (DM-global).
• RLONW: western longitude in degrees for each output (sub)domain; array of reals (DM-global).
• RLONE: eastern longitude in degrees for each output (sub)domain; array of reals (DM-global).
• NFPSIZEG: number of points in each subdomain (DM-global).
• NFPSIZEL: DM-local version of variable NFPSIZEG, its value is computed in SUFPG.
• NFPGP: maximum number of output points (DM-global). This is the sum on all the subdomains of the NFPSIZEG. Reduction of the grid near the poles for global output grids is not taken in account, so NFPSIZEG can be above the actual total number of points where interpolations will have to be done.
• NFPD1: first dimension of the array to be written on output file (DM-global). NFPD1 can be above NFPGP for global domains (NFPD1 counts polar latitudes contrary to NFPGP) and ALADIN domains (NFPD1 can count extension zone points according to the value of NDOMFP in NAMFPC but NFPGP does not count any point of the extension zone).

These variables have many possible default values, according to the content of the namelist NAMFPC.

ARPEGE default values (LELAM=.FALSE.) for NLAT, NLON, RLATN, RLATS, RLONW, RLONE:

• if CFPFMT='GAUSS' or CFPFMT='MODEL', the default values are: NLAT=NDGL, NLON=NDLON, while the other variables are not useful.
• if CFPFMT='LALON', there are many possible default values, according to the value of CFPDOM in NAMFPC:

If CFPDOM(j) is uninitialised or unknown from FULL-POS, then the default values are all null, and you must at least specify in the namelist the values of NLAT and NLON, otherwise the job will abort.

• If CFPFMT='LELAM', there are many possible default values, according to the value of CFPDOM in NAMFPC (see SUFPD, for real quantities there are often more digits than written in the following table):

ALADIN default values (LELAM=.FALSE.) for NLAT, NLON, RLATN, RLATS, RLONW, RLONE:

They are not detailed here and computation is sometimes complicated, see routine SUFPD for more details.

Additional variables required for a grid ALADIN:

If you ask for a grid ALADIN (CFPFMT='LELAM'), there are additionnal variables that you can specify:

• NFPLUN: actual first row of longitude (DM-global).
• NFPLUX: actual last row of longitude (DM-global).
• NFPGUN: actual first row of latitude (DM-global).
• NFPGUX: actual last row of latitude (DM-global).
• NFPZONL: half the size of area I in abscissa x (DM-global).
• NFPZONG: half the size of area I in ordinate y (DM-global).

There are many possible default values, according to the value of CFPDOM in NAMFPC; for NFPLUX and NFPGUX there are two possible default values according to the value of NFPDOM, the first one is valid when NFPDOM=0, the second one is valid when NFPDOM=1 or -1:

Furthermore, in ARPEGE/IFS, it is also possible to perform at the end an overtruncation of each post-processed field. This overtruncation is equivalent to the so-called "THX" filter, but it is applied in the stretched spectral space and then n0 (see formula ( [Ref: deffilterTHXARPEGE] ) ) is equal to the variable NPMAX in the namelist NAMDIM. Note that this overtruncation is active only if NPMAX is less than NSMAX.

2.12.15 YOMFPIOS.

Contains control variables for FULL-POS IO scheme. Variables are initialised in setup routine setup/SUFPIOS.

Writing to output files: variable NFPXFLD.

To write post-processed fields on an output file, you first extract them from an array (or a work file). Rather than extracting the fields one after the other, the fields are grouped in packets, and these packets of fields are extracted one after the other. You can specify the maximum number of fields in a packet by modifying the variable NFPXFLD in the namelist NAMFPIOS. The default value is the maximum possible depending on the number of fields to produce. Raising the value of NFPXFLD should save CPU time to the detriment of the memory cost, and vice versa.

Additional remarks and some default values:

For the horizontal post-processing, the data flows have been separated in 4 parts:

• post-processed dynamical data.
• post-processed physical and fluxes data.
• weights for horizontal interpolations.
• output geometry and climatology.
• horizontally pre-processed dynamical data (for post-processing on height levels or hybrid levels).

To spare memory space, each of these data flows can be controlled by a specific I/O scheme. By default, no I/O scheme is activated. If you wish to activate I/O schemes, then use the variables which are in the namelist NAMFPIOS as the array below describes it (defaults values are the ones in parenthesis).

2.12.18 YOMFPSC2.

Contains control variables for SCAN2MSM or SCAN2MDM FULL-POS rows. Variables are initialised in setup routine setup/SUFPSC2.

List of variables:

• NFPLENR: number of active points in each post-processing row (DM-local).
• NFPROMAG: working dimension for horizontal post-processing (DM-global if its value is specified in the namelist NAMFPSC2, DM-local in the contrary, default value depends on the processor if distributed memory).
• NFPROMAL: working dimension for horizontal post-processing, DM-local version of NFPROMAG.
• NFPBSR: number of sub-rows in each post-processing row (DM-local).
• NFPTBSRL: total number of sub-rows in post-processing buffer (DM-local).

Additional remarks about variables NFPROMAG and NFPROMAL:

Variable NFPROMAG is very useful to find a compromise between the vectorization and the memory cost in the post-processing for the lagged computations (horizontal interpolations in HPOSLAG and additional calculations in ENDVPOS), and it is also very useful to make efficient I/O schemes. The variable NFPROMAL represents the horizontal depth of work in the lagged computations of post-processing; it is obvious that this variable has some similarity with the famous variable NPROMA (in namelist NAMDIM) or the less famous variable NSEGM (in namelist NAM926), but its use is more flexible. For shared memory NFPROMAL=NFPROMAG if NFPROMAG is an odd integer, NFPROMAL=NFPROMAG+1 if NFPROMAG is an even integer; this is also the case if NFPROMAG is taken to its (DM-local) default value for distributed memory, this is not necessary to define a unic DM-global value (but desirable in the future). For distributed memory when a DM-global value of NFPROMAG is given in the namelist NAMFPSC2, NFPROMAL depends on the processor, its maximum value is equal to NFPROMAG if NFPROMAG is an odd integer, NFPROMAG+1 if NFPROMAG is an even integer. Variable NFPROMAG is used only in SUFPSC2, the remainder of the code uses only NFPROMAL. The way how the post-processing data flow is managed in the post-processing arrays/work files is explained in detail in the sections 'Some shared memory features' and 'Some distributed memory features'. For summary:

• The model data is split in packets of points of fixed size NPROMA; each model packet is treated by one task, and is independent from the other packets. For distributed memory one processor treats NGPTOT model grid-points, with a subdivision into NPROMA-packets, but this subdivision is active for not lagged computations only.
• Each output point (i.e. where post-processing is performed) is related to one model packet: the one which contains the model point which is the nearest from it. That way, the output points are sorted out, so that each post-processing packet (i.e. the group of all the output points which are related to the same model packet) has a specific size. For shared memory (resp. distributed memory) the model-packets used to compute NFPROMAG and NFPROMAL are the NPROMA-packets (resp. the NGPTOT-packets).
• In order to use the I/O subroutines already available in ARPEGE/IFS, each post-processing packet has been split in sub-rows of fixed size NFPROMAL. Each post-processing packet is treated by one task which performs a loop on the number of sub-rows in the current post-processing packet.
• Note that an empty post-processing packet is characterized by a number of sub-rows equal to zero; as a consequence, empty post-processing packets do not lead to memory spill. On the opposite, each non-empty post-processing packet contains a specific number of unused words.

Searching for a compromise between vectorization and memory cost, the value of NFPROMAG can be any integer from 1 to the size of the biggest post-processing packet. The bigger NFPROMAG will be, the more the vectorization will be efficient, and the more memory will be needed. The default value of NFPROMAG is the mean size of the post-processing packets if shared memory, the total number of post-processing points treated by the current processor if distributed memory, as this value appeared to be the best compromise. However, if the I/O schemes are activated, the size of the biggest post-processing packet may be a more efficient value. In the listing, the user will find more information to find out the value to adopt: just before "COMMON YOMFPSC2" is printed out, the following information is written (information depends on the processor for distributed memory but is not very useful in this case because there is only one value per processor which is used to compute the following statistics: the standard deviation is zero):

• size of the smallest post-processing packet.
• size of the biggest post-processing packet.
• mean size of the post-processing packets.
• standard deviation of the size of the post-processing packets.

You can also know the memory you have lost in the post-processing arrays: just locate "TOTAL MEMORY LOST IN WORDS =" .

2.12.22 YOMIOS.

• fitted post-processed fields.

To spare memory space, the data flow of unfitted post-processed fields can be controlled by a specific I/O scheme. By default, this I/O scheme is activated only at ECMWF (LECMWF=.TRUE.). If you wish to activate/deactivate it, just set LIOGAUX=.TRUE./.FALSE. in the namelist NAMCT0. Then you can change other related variables in the namelist NAMIOS:

2.12.34 Additional namelists, containing local variables.

These namelists are NAMFPPHY (read in routine setup/SUFPPHY), NAMFPDY2, NAMFPDYP, NAMFPDYH, NAMFPDYV, NAMFPDYT and NAMFPDYS (read in routine setup/SUFPDYN). These namelists can be used to make an accurate list of post-processed fields.

In ordinary case, at each post-processing time step, all the fields that are written in the namelist NAMFPC are post-processed at all the levels and for all the output domains written in the namelist NAMFPC. However, it is possible to get, at each post-processing time step, exactly the fields you wish, and nothing more: in that case, you have to make other namelists file which will contain the selection of the fields you wish to get. First, you have to set in NAMCT0 the variable CNPPATH as the directory where the selection files will be. Under this directory, the name of a selection file must be xxtDDDDHHMM, where DDDDHHMM specifies the date/time of the post-processing time step. Then a selection file must contain 7 new namelists (see above).

Namelist NAMFPPHY:

Namelist NAMFPPHY is for physical fields and fluxes; it contains the following DM-global parameters:

• CLPHY: names of selected physical fields; array of 16 characters.
• CLDPHY: names of selected subdomains, separated by ":", for each selected physical field; characters array (example: 'DOM1:DOM2:DOM3').
• CLCFU: names of selected cumulated fluxes fields; array of 16 characters.
• CLDCFU: names of selected subdomains, separated by ":", for each selected cumulated flux; characters array (example : 'DOM1:DOM2:DOM3').
• CLXFU: names of selected instantaneous fluxes fields; array of 16 characters.
• CLDXFU: names of selected subdomains, separated by ":", for each selected instantaneous flux; characters array (example : 'DOM1:DOM2:DOM3').

Namelist NAMFPDY2:

Namelist NAMFPDY2 is for 2D dynamical fields; it contains the following DM-global parameters:

• CL2DF: names of selected fields; array of 16 characters.
• CLD2DF: names of selected subdomains, separated by ":", for each selected field; characters array (example : 'DOM1:DOM2:DOM3').

Namelists NAMFPDYP, NAMFPDYH, NAMFPDYV, NAMFPDYT and NAMFPDYS:

These namelists are for fields post-processed respectively on pressure levels, height levels, potential vorticity levels, isentropic levels and hybrid levels; they contain the same following DM-global parameters:

• CL3DF: names of selected fields; array of 16 characters.
• IL3DF: list of selected indexes of post-processing levels, for each selected field; integer array of 2 dimensions; first subscript is for selected post-processing level; second one is the local field index.
• CLD3DF: names of selected subdomains, separated by ":", for each selected level and each selected field; characters array of 2 dimensions; first subscript is the local index of the selected level; second one is the local field index (example : 'DOM1:DOM2:DOM3').

Note that all the fields or levels or domains written in a selection file should be included in the main namelist NAMFPC, otherwise the job will abort. Default value of namelist quantities is 0 for IL3DF and ' ' for character quantities.
