decorrelation

Observations influence in the model error subspace can be decreased using decorrelation functions. The data assimilation code provide users with a large range of isotropic functions for this purpose.

The following lines describes the shape functions collection.

  • linear function:
    decorrelation1
  • step function:
    decorrelation2
  • spherical function:
    decorrelation3
  • sinusoidal function:
    decorrelation4
  • exponential function class
