Analysis of ICESat data using Kalman filter and kriging to study height changes in East Antarctica
[1] We analyze ICESat derived heights collected between Feb.03–Nov.04 using a kriging/Kalman filtering approach to investigate height changes in East Antarctica. The model’s parameters are height change to an a priori static digital height model, seasonal signal expressed as an amplitude B and phase...
