varinfo.yaml

varinfo.yaml

The varinfo.yaml file specifies ROMS input and output fields metadata. Starting svn revision -r 1902 released on March 1, 2022, the ROMS metadata is managed with a YAML file, and the regular text file varinfo.dat is deprecated. The YAML files are simple, easy to follow, elegant, portable, and expandable. ROMS now can process YAML files with its parser module, yaml_parser.F. Therefore, there is no need to use third-party YAML parsers. Basically, varinfo.yaml have the following structure:

svn_repository: $URL$
convention: CF 1.10

#shortwave: &SWRAD swrad_daily
shortwave: &SWRAD swrad

metadata:

- variable: temp # Input/Output
standard_name: sea_water_potential_temperature
long_name: potential temperature
units: Celsius # [Celsius]
field: temperature
time: ocean_time
index_code: idTvar(itemp)
type: r3dvar
add_offset: 0.0d0
scale: 1.0d0

- variable: *SWRAD # Input/Output
standard_name: net_downward_shortwave_flux_at_sea_water_surface
long_name: solar shortwave radiation flux
units: watt meter-2 # Input: [Watt/m2]
field: shortwave radiation # [Celsius m/s]
time: srf_time # Output: [Watt/m2]
index_code: idSrad
type: r2dvar
add_offset: 0.0d0
scale: 1.0d0

The field key and value pair in the YAML blocking list is as follows:

• variable: is the variable name (shortname) as defined in input/output NetCDF files. If you have a forcing NetCDF file that uses a different variable name, you don’t need to rename the variable in the forcing file. Just change it value in varinfo.yaml.
• standard_name: is the variable standard_name NetCDF attribute, which follows CF conventions. A list of all standard_name attribute are shown below.
• long_name: is the variable long_name NetCDF attribute.
• units: is the variable units NetCDF attribute. It is a tricky key/value pair in ROMS. In output NetCDF files, it describes the units of output attribute and data. For variables that are used on input only, such as meteorological data, we have assumed a convention that its value describes the units that you have in your NetCDF file. It does not strictly describe the units ROMS assumes internally (though this is generally true if the scale factor is 1.0d0). The scale can be used to make ROMS modify the data during input to be consistent with ROMS internal units without the need to re-create a new forcing file with adjusted units.
• field: is the variable field NetCDF attribute. It is a user-customizable attribute that can be used to create labels during post-processing for plotting, visualization, and so on. It can be in any language represented by the 255 ASCII sets of characters, letters, symbols, and signs).
• time: is the variable associated time NetCDF attribute, if record dependency. If your NetCDF file uses a different name from the default you don’t need to rename it in the NetCDF file, you can modify varinfo.yaml. However, it is not necessary nowadays because ROMS inquiry.F module search for the variable time attribute internally, and use that time variable during the processing. In such case, the value in varinfo.yaml is ignored and overwritten.
• index_code is an internal and unique ROMS descriptor index for the information arrays. You cannot change it value because it used internally in ROMS to manage metadata.
• type: is the variable staggered Arakawa C-grid type:

C-grid Type	Description
nulvar	non-grided variable
p2dvar	2D Ψ-variable, grid cell corners
r2dvar	2D ρ-variable, grid cell center
u2dvar	2D U-variable, grid cell x-edges
v2dvar	2D V-variable, grid cell y-edges
p3dvar	3D Ψ-variable, grid cell corners
r3dvar	3D ρ-variable, grid cell center
u3dvar	3D U-variable, grid cell x-edges
v3dvar	3D V-variable, grid cell y-edges
w3dvar	3D W-variable, grid cell y-edges
b3dvar	3D BED-sediment variable, grid cell center
l3dvar	3D spectral light variable, grid cell center
l4dvar	4D spectral light variable, grid cell center

• add_offset is the value to be added to input NetCDF data. Currently, not used.
• scale is the factor to multiply input data for units conversion purposes. For example, ROMS assumes surface air pressure is given in millibars. The COARE bulk formulae in bulk_flux.F demand this. If your input file is in Pascals you can convert these using the scale entry. You would set its to 0.01d0 because 1 Pascal = 0.01 millibar. In general, the rule is:

ROMS_internal_units = (your_units) x (scale) + add_offset

If you change the scale factor in your varinfo.yaml, We recommend you change the units string to be consistent with your data file, and insert a comment to remind yourself what you’ve done in using a new scale factor. You can append a comment using a hash # after any entry in varinfo.yaml.

YAML allows alias and anchor to avoid repetition. However, here is used to select the desired option for input shortwave radiation data. If processing daily values, the input variable is specified by the anchor &SWRAD and its value swrad_daily is used to replace the alias token *SWRAD. In this case, the DIURNAL_SRFLUX option needs to be activated in ROMS to modulate the shortwave radiation by the local daily cycle at each timestep. Notice, that this strategy is commented by default. In YAML, single or multiple line comments start with a hash #. Also, comment after a key/value pair is allowed. All comments are skipped during processing.

Vinfo() entries

Vinfo(1): The principal role of varinfo.dat is to make the connection between the unique index variable name that ROMS uses (Vinfo(6)) and the name of the corresponding variable in the NetCDF file (Vinfo(1)).

Example: The default varinfo.dat uses the name swrad for the solar shortwave radiation flux in the forcing NetCDF file. If you have a forcing NetCDF file that uses a different name, say shortwave, you don’t need to rename the variable in the forcing file. Just change the Vinfo(1) entry in varinfo.dat to shortwave, and ROMS will find it.

Vinfo(6): . This is the name by which variables are referred to internally in ROMS.

Vinfo(5): This is the time variable name associated with the data. If your NetCDF file uses a different name from the default you don’t need to rename it in the NetCDF file, just in varinfo.dat.

Example: If your file of shortwave radiation data is a time series defined at times given by variable shortwave_time then change the Vinfo(5) entry to this from the default srf_time.

Note: If the data in your NetCDF file has an attribute of time the entry in Vinfo(5) is ignored, and the time variable indicated in the NetCDF is used instead.

Vinfo(3) and scale: This is possibly the trickiest part of varinfo.dat and a place where one can easily make an error.

Note: For output only variables, the Vinfo(3) units string is used on output to describe the data in an output NetCDF file units attribute.

For variables that are used on input only, such as meteorological data, we have assumed a convention that Vinfo(3) describes the units that you have in your NetCDF file. It does not strictly describe the units ROMS assumes internally (though this is generally true if the scale factor is 1). The scale can be used to make ROMS modify the data during input to be consistent with ROMS internal units without the need to re-create a new forcing file with adjusted units.

Example: ROMS assumes surface air pressure is given in millibars. The COARE bulk formulae in subroutine bulk_flux demand this. If your input file is in Pascals you can convert these using the scale entry. You would change scale from its default of 1.0d0 to 0.01d0 because 1 Pascal = 0.01 millibar. Note that the rule is

ROMS_internal_units = (your_units) x (scale)

Hint: if you google search the string convert pascal to millibar you’ll get the necessary scale factor without overly taxing your brain.

If you change the scale factor in your varinfo.dat, I recommend you change the units string in Vinfo(2) to be consistent with your data file, and insert a comment to remind yourself what you’ve done in using a new scale factor. You can append a comment using a ! after anyentry in varinfo.dat.

Here is a table of common conversions that might be required:

Index Code	Variable	Long Name	Required Units	Other Units	Add Offset	Scale
idPair	Pair	surface air pressure	millibar	Pascal	0.0d0	0.01d0
idTair	Tair	surface air temperature	Celsius	Kelvin	-273.15d0	1.0d0
idQair	Qair	surface air relative humidity	Fraction	Percent	0.0d0	0.01d0
idCfrac	cloud	cloud fraction	Fraction	Percent	0.0d0	0.01d0
idSrad	swrad	solar shortwave radiation flux	Watts meter-2	Joule second-1 meter-2	0.0d0	1.0d0
idrain	rain	precipitation flux	kilogram m-2 second-1	meter second-1	0.0d0	1/rhow (0.001d0 m3/kg)
idsfwf	swflux	surface net freshwater flux (E-P)	meter second-1	meter second-1	0.0d0	1.0d0
idUsms	sustr	surface u-momentum stress	newton meter-2	dyne centimeter-2	0.0d0	0.1d0

Input and output variables

Some variables described in varinfo.dat are both input and output variables. The model state variables zeta, temp, salt, u, v…etc. are obviously in this category. Certain surface flux variables can be either input forcing data, or output results computed internally.

Example: In some ROMS configurations, such as #define BULK_FLUX, surface u-stress, sustr, is an output having been computed internally. It is written to the output NetCDF file if Hout(idUsms) = T in the roms.in file.

In other configurations sustr is an input, and drives the surface momentum input directly.

The scale factor is only used on input. It is ignored on output. Output data are always written in default ROMS internal units with a few exceptions: namely, heat fluxes and surface and bottom stresses. The output scale factors applied can be seen in the source code (e.g. wrt_his.F). This re-scaling is made to give geophysically meaningful units of Watt/m2 for heat, and N/m2 (or Pa) for stresses.

We will add more documentation on the default internal units, and the distinction between input and output varibales, in the next model release.

CAUTION: You must be very careful here if you start tinkering with varinfo.dat entries for mixed I/O variables.

Example: If you intend surface wind stress tau, sustr, as an input but have a data file in dynes/cm2 (= 0.1 N/m2 or Pa), you need to convert these to ROMS internal units of kinematic stress tau/rho0 (like u*2) of m2/s2. The scale factor is 0.1/1025 = 9.8x10-5 where the numerator 0.1 converts dynes/cm2 to Pa and the reference density of seawater is 1025 kg/m3.

The conversion of momentum (in Pa) and heat flux (in Watts/m2) to kinematic units (of m2/s2 and degC m/s, respectively) is why the report of min/max values sent to stdout shows different values to those you have in your input NetCDF file. You should always carefully inspect the range of data values read when working with a new model set-up or new forcing netCDF files to make sure the data you are reading are what you expect. In the next version of the model will will clarify these procedures by documenting within varinfo.dat the default input and output units, and the internal units.

If you intend sustr to be an output you should keep the units string Vinfo(3) as newton meter-2 because this string will be the units attribute in the output NetCDF file. The scale value is irrelevant because it will not be applied on output. You can’t use it to alter the units of the output.

If you specify sustr as input and output (which you can do: ROMS will read forcing sustr from a forcing NetCDF file and write sustr to history, averages, stations file etc.) even if you do a scale factor conversion you’d better keep the Vinfo(3) units as Newton meter-2 so that the output files have the correct metadata in the NetCDF attributes.

Surface fluxes of tracers are always output in units of tracer_units m/s. This is true also for the surface salt flux. It is not converted to an equivalent freshwater flux. The variable swflux is an input variable only. You can do the conversion yourself if you wish using a suitable surface salinity value. We do not do this conversion within ROMS because in order to perform a tracer budget analysis you would want fluxes in tracer units.

However, if you are using the BULK_FLUXES option, you can have the computed evaporation rate (in kg m/s) saved to the output file, and perform a freshwater budget calculation accordingly.

We don’t recommend mixing the units of state variables on input and output. A user could give an initial condition file with sea level zeta in centimeters by setting the scale to 0.01. The output history, averages, restart etc. files will nevertheless be written with zeta in units of meters. So you would want the Vinfo(3) string to reflect this. The risk here is that if you subsequently restart the model from one of these files, you would need to remember to re-set the scale for zeta in varinfo.dat.

Note also that in if you specify stresses or heat fluxes through analytical.F that they must be converted to kinematic units within analytical.F, i.e. stress in Pa must be divided by rho0, and heat fluxes by rho0*cp.

A nifty varinfo.dat trick

The variable keyword does not have to be unique. You can direct more than one index_code identifier to read the data from the same NetCDF variable in the input files. The scale value allow you to apply different scaling to each.

For example, suppose you wish to specify a constant value for the open boundary values for biological tracers. Rather than make a NetCDF file with data for all of NO3_west, NH4_west, phyt_west, and etc, you could make a NetCDF file with a single variable named, say ONES_west, which is filled with nothing but 1.0 for all time coordinate values.

In varinfo.yaml, there must still be one entry for each unique index_code but you can have each entry point to the same ONES_west data. Assign the value you want for each variable in the scale entry. This scale will be multiplied by the 1.0 on input to set the open boundary values.

- variable: ONES_west # Input
standard_name: mole_concentration_of_ammonium_expressed_as_nitrogen_in_sea_water
long_name: ammonium western boundary condition
units: millimole_nitrogen meter-3 # [millimole/m3]
field: NH4 western-boundary
time: NH4_time
index_code: idTbry(iwest,iNH4_)
type: nulvar
add_offset: 0.0d0
scale: 0.1d0 # make all values equal to 0.1 millimole meter-3

- variable: ONES_west # Input
standard_name: mole_concentration_of_phytoplankton_expressed_as_nitrogen_in_sea_water
long_name: phytoplankton western boundary condition
units: millimole_nitrogen meter-3 # [millimole/m3]
field: phytoplankton western-boundary
time: phyt_time
index_code: idTbry(iwest,iPhyt)
type: nulvar
add_offset: 0.0d0
scale: 0.08d0 # make all values equal to 0.08 millimole meter-3
