Hi everyone!

I interpolated observed precipitation on a grid.  I also kept variance (from krige) and error (from krige.cv).  I have some questions about the signification of those quantities.

I obtain some interesting results.  For example, the variance from "krige" is around 24 and 40 (mm?  same unit as the raw variable?), while the seasonal maximum amount are around 22 and 45mm.  So, is it normal that the variance is so high?  Does it mean that the interpolation that I did have a major flaw?

Because for temperature, the variance (3.6 to 4.6) is quite low compared to the mean amount of temperature (~26-29 C).

Sorry if it's not the right place to ask those questions but I didn't found an adequate answer yet.
