using IDW with anisotropy
Are you interpolating in 3D (x,y,t)?

hello, I have a timseries dataset of monthly precip data from rain guages. The coverage is relatively sparse (approx 30 stations covering the country) and there is strong anisotropy in the data - at the monthly timestep data is strongly correlated in the E-W direction. Is there any way to use modify the IDW interpolation in gstat, to incorporate a directional bias in the distance weight? many thanks for any suggestions
