Answer 1

This tutorial covers a range of interpolation available in numpy/scipy. If you want to just one direction, I would work on each row independently and then re-assemble the results. You might also be interested is simply smoothing your data (exmple, Python Smooth Time Series Data, Using strides for an efficient moving average filter).

def smooth_inter_fun(r):
    #what ever process you want to use
new_data = np.vstack([smooth_inter_fun(r) for r in data])
