[R-sig-Geo] spatiotemporal co-kriging?

[Santiago Beguería Portugués]

Dear R-sig-geo list members,

I am working on a spatio-temporal kriging model (using gstat::krigeST) of two closely related variables. I’m getting good results on one of them, and not so good on the other. Since both dependent variables are inter-related, I expect that co-kringing would be a good option (I’ve done this in a spatial-only context with the same two variables and co-kriging proved beneficial).

So, is it possible to perform spatiotemporal CO-kriging, and if so are you aware of any examples? I have not been able to find any myself.

Cheers,
