摘要：
This paper presents two new schemes for interpolating missing samples in satellite diurnal temperature cycles. The first scheme, referred to here as the cosine model, is an improvement model proposed by G? ttsche et al and combines a cosine and exponential function for modelling the diurnal temperature cycle. The second scheme employs a Reproducing Kernal Hilbert Space interpolator for interpolating the missing samples. The application of reproducing kernel Hilbert space interpolators to the diurnal temperature cycle interpolation problem is novel. Results obtained by means of computer experiments are presented.
