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, Santiago Beguer?a CSIC Spain
spatiotemporal co-kriging?

As for gstat: I think you can't with krigeST, but you may succeed with krige when you take time as the third dimension -- of course this constrains the variogram models you can choose from to the metric model.
