ECCO-V4r3 interpolated monthly model output

NASA JPL ECCO-V4r3 model output

Version 4 is the first multi-decadal ECCO estimate that is truly global, including the Arctic Ocean. The Release 3 edition includes improvements in time-period (1992-2015), model (e.g., sea-ice), observations (e.g., GRACE, Aquarius), and constraints (e.g., correlated errors).

The model that is used to produce v4r3 is MITgcm version checkpoint66g. Wang (2017) gives a detailed description about how to download the code, data, and any needed auxiliary files to reproduce v4r3.

Output provided here contains the monthly model fields interpolated onto a regular lat-lon grid with 0.5 degree resolution in both directions.
