 v8 [[Image(image-20140617-163609.png)]] Note that WFDEI provides data for land areas only. 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") }}} [[Image(image-20140617-170438.png)]] In the particular case of global domain selections (lonLim and latLim arguments set to NULL), it is recommended that only single-member, single-year selections are performed, due to the large size of this type of requests. Finally, in the particular case of global domain selections (lonLim and latLim arguments set to NULL), it is recommended that only single-member, single-year selections are performed, due to the large size of this type of requests.
