ACCURACY ESTIMATION OF RECENT GLOBAL OCEAN TIDE MODELS USING TIDE GAUGE DATA
利用验潮站资料评估全球海潮模型的精度

Due to the availability of multi-satellite altimetry and advances in numerical simulation methodologies in recent 20 years,recent global ocean tide models are well known to 2 cm RSS(root square of the sum of the squares of the 8 rms values) and with a spatial resolution of 50 km in deep ocean.The paper is aimed to validate the performance of five models by using tide gauge data.The results show that the performance of NAO99b is best in China sea areas,its RSS is 14.86 cm.Compared with other contemporary models,EOT10a fit the tide gauge data in global distribution better.
