ARGO数据的一个问题是,在大多数情况下,它没有提供真正的海洋表面的数据。当他们从漂流深度提升(通常在1000或2000米)的表面,他们中的大多数停止记录从表面的深度是5米。从海鸟(公司提供,供在大多数ARGO浮标传感器,SSalOceanSciencesMar08-5Pages.pdf):“…避免摄取海洋表面污染物降解盐度精度,泵关闭约5分巴表面下阿尔戈浮动提升”。This creates problems when assimilating into atmospheric models because of inconsistencies between the satellite-derived sea surface temperature and the ARGO temperature at 5 meters. To address this issue and provide better surface flux information, some ARGO floats are equipped with a second temperature and salinity sensor (STS) that only measures in the proximity of the surface.
