Jump to navigationJump to searchROMS I/O Metadata File: 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 can now process YAML files with its parser module, yaml_parser.F. Therefore, there is no need to use third-party YAML parsers. Basically, varinfo.yaml has the following structure:

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.
- 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.
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.
Input Fields Scaling
For variables that are used on input only, such as meteorological data, we have assumed a convention that the units keyword describe 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 value 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.
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.
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 field metadata described in varinfo.yaml are both input and output variables. The model state variables zeta, ubar, vbar, u, v, temp, salt, and passive tracers are obviously in this category. Also, certain surface flux variables can be either input forcing data, or output results computed internally.
For example, in some ROMS configurations when BULK_FLUX is activated, surface u-stresses (sustr and svstr) are output fields computed internally in the surface boundary layer formulation. Such fields are written to the output history NetCDF file if Hout(idUsms) = T and Hout(idVsms) = T in the roms.in file. Otherwise, in other configurations sustr and svstr are input that drives the surface momentum forcing directly.
The scale factor is only used on input. It is ignored on output and 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.
CAUTION: You must be very careful here if you start tinkering with varinfo.yaml entries for mixed I/O variables.
For example, if you intend surface wind stress, sustr (taux), as input but have a data file in dynes/cm2 (equals to 0.1 N/m2 or Pa), you need to convert these to ROMS internal units of kinematic stress taux/rho0 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 stress (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 standard output 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 ensure that the data you are reading is what you expect.
If you intend sustr to be an output you should keep the units string 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, quicksave, averages, and stations.) even if you do a scale factor conversion you’d better keep the scale keyword units as Newton meter-2 so that the output files have the correct metadata in the NetCDF attributes.
Surface fluxes of salinity and passive tracers are always written in units of tracer_units m/s. 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 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, and other files will nevertheless be written with zeta in units of meters. So you would want the units keyword 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.yaml.
Note that if you specify stresses or heat fluxes with analytical functions, they must be converted to kinematic units within analytical.F. That is, stresses in Pa must be divided by rho0, and heat fluxes by rho0*cp.
A nifty varinfo.yaml 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.
