repeated_dates

The repeated_dates source is used to repeat a single source multiple times, so that its data is present at multiple dates. A simple example of this is when you have source that contains a constant field, such as orography or bathymetry, that you want to have repeated at all the dates of the dataset.

The generale format of the repeated_dates source is:

repeated_dates:
    mode: mode
    # ... parameters related to the mode ...
    source:
      # ... a source definition ...

where source is any of the operations or sources described in the previous sections. The mode parameter can be one of the following:

constant

repeated_dates:
  mode: constant
  source:
      xarray-zarr:
        url: dem.zarr
        variable: dem

climatology

repeated_dates:
    mode: climatology
    year: 2019
    day: 15
    source:
        grib:
          path: some/path/to/data.grib
          param: [some_param]

closest

repeated_dates:
    mode: closest
    frequency: 24h
    maximum: 30d
    skip_all_nans: true
    source:
      grib:
          path: path/to/data.grib
          param: [some_param]
