+Note that WFDEI provides data for land areas only, and its spatial resolution is much higher that CFS (1º vs 0.5º). In order to compare both datasets, it is first necessary to put them in the same grid (i.e., to interpolate). We use the bilinear interpolation algorithm of package `fields` to this aim, included in the function `interp.surface.grid`:
+
+{{{
+> obs.regridded <- interp.surface.grid(obj = list(x = x.obs, y = y.obs, z = observed), grid.list = list(x = x, y = y))
+> par(mfrow = c(1,2))
+> image.plot(member1 - obs.regridded$z, asp = 1, main = "Bias Member 1")
+> image.plot(member2 - obs.regridded$z, asp = 1, main = "Bias Member 2")
+}}}
