如科尔等人，2015年（来自Argo浮标观测的涡流搅拌和水平扩散率：地理和深度变化，地球物理研究快报，42，3989-3997，doi：10.1002/2015 GL 063827），并更新以包括1°和3°版本以及2005-2015年的Argo数据。只要满足最低数量的剖面，并且估计的混合长度不超过指定的阈值，就可以在62°S和62°N之间估计扩散率。这些条件因表面深度/密度而异。估计的涡动扩散率表现出随地理位置和深度的变化。
This dataset was processed as documented in Cole et al., 2015 (Eddy stirring and horizontal diffusivity from Argo float observations: Geographic and depth variability, Geophysical Research Letters, 42, 3989-3997, doi:10.1002/2015GL063827) and updated to include 1° and 3° versions as well as Argo data from 2005-2015. Diffusivity is estimated between 62°S and 62°N whenever the minimum number of profiles is met and the estimated mixing length does not exceed the designated threshold. These conditions vary by depth / density surface. The estimated eddy diffusivity exhibits variability with geographic location and with depth.
