Description
I added a new option SPLINES_VCONV to 4DVAR background/model error covariance convolutions using the parabolic splines (implicit algorithm) reconstruction of the diffusion operator. Therefore, there are now three algorithm for vertical convolution (VCONVOLUTION):
1) Explicit
2) Implicit (IMPLICIT_VCONV)
3) Implicit, parabolic splines reconstruction (SPLINES_VCONV)
