ObsFunctionVelocity

This obsFunction is designed to compute wind speed based on u(windEastward) and v(windNorthward) components of wind.

Required input parameters:

windEastward

zonel velocity, i.e. the component of the horizontal wind TOWARDS EAST

windNorthward

meridional velocity, i.e. the component of the horizontal wind TOWARDS NORTH

Example configuration:

Here is an example to use this obsFunction to compute velocity and then reject data if the velocity value is bigger than maxvalue.

  filter variables:
  - name: windEastward
