导致全球海平面短时间尺度变化主要有海水密度和海水质量这两方面的变化因素。通过重力校正和气候试验(GRACE)对地球重力场进行观测,并联合卫星测高SA、ARGO系统的观测结果可推知:自2003年以来,海平面的上升主要是因为海水质量的增加。1 GRACE数据反演的海水质量变化根据GFZ公
The short-term changes in the global sea level caused by major changes in seawater density and seawater quality are two factors. Observation of the Earth’s gravitational field through the Gravity Correction and Climate Experiment (GRACE) combined with the observations of the satellite altimetry SA and ARGO systems shows that the sea level rise has been mainly due to the increase of seawater quality since 2003. 1 GRACE data inversion of seawater quality changes according to GFZ
