by Laurent Roblou — last modified Apr 23, 2012 01:55 PM

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:

 

 

  • step function: R-STEP

 

 

  • spherical function:

 

 

  • sinusoidal function:

 

  • exponential function class

 

  • Gaussian functions class:
