◆ fv3jedi_covar_delete()

subroutine fv3jedi_covariance_mod::fv3jedi_covar_delete ( type(fv3jedi_covar), intent(inout) self )

Parameters

[in,out] self Covariance structure

Definition at line 43 of file fv3jedi_covariance_mod.f90.

Here is the caller graph for this function:

◆ fv3jedi_covar_setup()

subroutine fv3jedi_covariance_mod::fv3jedi_covar_setup	(	type(fv3jedi_covar), intent(inout)	self,
		type(fv3jedi_geom), intent(in)	geom,
		type(c_ptr), intent(in)	c_conf
	)

Setup for the model's 3d error covariance matrices (B and Q_i)

This routine queries the configuration for the parameters that define the covariance matrix, and stores the relevant values in the error covariance structure.

Parameters

[in,out]	self	Covariance structure
[in]	c_conf	Configuration
[in]	geom	Geometry
