测高数据在计算海平面时的取权
The Weighting in Mean Sea Level Computation Using Altimeter Data
-
摘要: 根据卫星测高数据分布所具有的低纬时稀疏、高纬时密集的特点,提出了计算平均海平面时非交叉点数据的解析定权公式和交叉点数据的解析定权公式。Abstract: According to the inhomogeneity of altimeter data distribution over ocean, the authors propose two methods for weighting in altimeter data processing, one for crossover points and the other for non-crossover points. It shows that the suggested methods are better than the former methods proposed by other authors.
