High-resolution 4DVAR-based Gulf Stream data-assimilative model product

This dataset contains results from a Regional Ocean Modeling System (ROMS)
that covers the northwestern Atlantic Ocean, including the U.S. East
Coast, Caribbean, and Gulf of Mexico. The model uses a horizontal grid
spacing of 7 kilometers (1/15 degree) and has 36 vertical layers. It
applies a 4D variational data assimilation algorithm with a strong
constraint, assimilating satellite-based sea surface height and sea
surface temperature measurements as well as in situ temperature and
salinity profiles. The dataset contains model output for the two-year
study period from 2017 to 2018, including sea surface height, ocean
current components (u and v), temperature, and salinity.
