Detailed Description

Derive observation error from a file representing the variance or the covariance matrix.

See DataExtractor for details on the format of this file.

example configurations:

- Filter: Perform Action
  filter variables:
  - name: air_temperature
    channels: &all_channels 1-3
  action:
    name: assign error
    error function:
      name: DrawObsErrorFromFile@ObsFunction
      channels: *all_channels
      options:
        file: <filepath>
        channels: *all_channels
        interpolation:
        - name: satellite_id@MetaData
          method: exact
        - name: processing_center@MetaData
          method: exact
        - name: air_pressure@MetaData
          method: linear

Note that channel number extraction is implicit, using the channels selected and performed as an exact match before any user defined interpolation takes place.
