Description:It has been determined that the biases in temperature reports from Aircraft Meteorological Data Relay (AMDAR) measurements exhibit a dependence, among other predictors, upon the vertical component, dh/dt, of the aircraft motion. While some aircraft report frequently and to the nearest second, and so provide data that are easily and directly applicable to the bias-correction problem, some other aircraft report infrequently and only to within the nearest minute, which makes it much harder to deduce their instantaneous vertical velocity component at each of their reporting times during their irregular ascending or descending flight trajectories. The problem of interpolating the likely vertical motion from such incomplete data seems suited to a solution by application of the method of numerical splines, which we describe in this short note. doi:10.7289/V59K485T (http://dx.doi.org/10.7289/V59K485T)
