[S] CoKriging Software

I am looking for software (Splus hopefully) that can be used to solve what
I think is a CoKriging Application. The application involves spatial
interpolation of air quality data (ozone) taken at a fixed number of monitoring
locations over some domain (e.g. multistate region). In addition to the
monitored ozone, we also have results from a numerical simulation model that
predicts ozone levels using emission data and meteorological information. Since
the monitoring data is spatially sparse ( e.g 5 to 30 monitors per state) and
the modeled data spatially dense (100's of grid cells per state), we would like
to be able to interpolate the measured ozone to areas not being monitored using
the modeling predictions as a covariate.

We are running Splus 3.4 on a SUN ULTRA. We also have Splus 4.0 in a Windows 95
environment. Any help (or ideas) would be appreciated.
