摘要

从水文的角度来看，威尼斯群岛是一个非常特殊的地区，因为它的水团变化。经常发生洪水，就需要定期监测水团的变化。为此，重力恢复和气候实验任务(GRACE)可以作为数据来源。本文的目的是比较GRACE FO新观测的最新结果。通过三个最重要的计算中心:JPL、GFZ、CSR，利用L3级、RL06释放的球面谐波度和阶次扩展高达120的数据对整个Venezia岛进行了比较。将结果与附近地区的月平均降水和蒸散发值以及潮汐计数据进行了比较。研究发现，总蒸散量与蒸散量及蒸散量变化无相关性

An Analysis of Total Water Storage Changes Obtained from GRACE FO Observations over the Venezia Islands Area Supported with Additional Data

The Venezia Islands are a very special area from the hydrological point of view due to its water mass changes. Regular floods results in the need for the regular monitoring of water mass changes. For this purpose, a Gravity Recovery and Climate Experiment mission (GRACE) can be used as a source of data. The aim of the paper is to compare the latest results of the new GRACE FO observations. The comparisons were carried out all over Venezia Island using the L3 level, RL06 release data obtained with spherical harmonics degree and order extension of up to 120, by the three most important computational cen‐ tres: JPL, GFZ, CSR. Results are compared to an average month values of pre‐ cipitation and evapotranspiration and tide gauge data in the nearby area. Based on the research, no dependence between TWS and evapotranspiration and evapotranspiration change were found
