Ocean state variables and atmospheric fluxes from forward sensitivity experiments based on ECCO Version 5 Release 5 (V4r5) Alpha

This dataset contains ocean state variables and atmospheric fluxes from forward sensitivity experiments based on the flux-forced version of ECCO Version 5 Release 5 (V4r5) Alpha. There are three experiments:- CTRL: Control run forced with total atmospheric forcings (including both seasonal and nonseasonal) from V4r5 Alpha- FWF: Same as CTRL, but wind stress is replaced by its mean seasonal climatology- WND: Same as CTRL, but net freshwater flux is replaced by its mean seasonal climatology All fields have been interpolated from the model's native grid to a regular 0.5 by 0.5 degree grid. Files are provided in NetCDF format.
