Covariance over time
timcovar.Rd
This operator calculates the covariance of two fields at each gridpoint over all timesteps. With S(x) = {t, i_1(t,x) != missval and i_2(t,x) != missval} it is o(1,x) = Covar{(i_1(t,x), i_2(t,x)), t_1 < t <= t_n} For every gridpoint x only those timesteps t belong to the sample, which have i_1(t,x) != missval and i_2(t,x) != missval.
