Comparisons of TOPEX/POSEIDON tidal solutions derived from the data of the first year of this altimetric mission with the best previous models and with in situ data show very substantial improvements. Typically, the gain in accuracy for the major lunar tidal component M(2) is 30 percent in root-mean-square differences with reference to a standard ground truth data set from 78 stations distributed over the world ocean. This is a major step, obtained because of the high quality of these altimetric data. The combination of these data with recent numerical models through assimilation methods is pointing toward solutions at the ultimate limits of practical accuracy.
将此次测高任务第一年的数据所得到的TOPEX/POSEIDON潮汐解与先前最好的模型以及现场数据进行比较，结果显示有了非常显著的改进。通常，对于主要的月球潮汐分量M(2)，相对于来自分布在全球海洋的78个站点的标准地面真值数据集，均方根差的精度提高了30%。这是一个重大进展，得益于这些测高数据的高质量。通过同化方法将这些数据与最新的数值模型相结合，正朝着实际精度极限的解决方案发展。
