NASA JPL ECCO-V4r4 model output
Version 4 Release 4 (V4r4), covering the period 1992-2017, represents ECCO's latest ocean state estimate. This product is an updated edition to that described by Forget et al. (2015, Geosci. Model Dev.). Version 4 is the first multi-decadal ECCO estimate that is truly global, including the Arctic Ocean. The Release 4 edition includes improvements in time-period (1992-2017), model (e.g., sea-ice), observations (e.g., GRACE, Aquarius), and constraints (e.g., correlated errors).
