Abstract:

This is a 3 km resolution regional model (ROMS, Regional Ocean Modeling System) output of the Gulf of Mexico sea surface height [cm] from 1993-01-01 to 2007-10-13. The regional model domain includes the Gulf of Mexico and part of the Caribbean Sea and the Gulf Stream and run in an ocean-only uncoupled mode. The model has been initialized and forced at the lateral open boundaries with fields from the uncoupled global 10-km CESM (Community Earth System Model) FOSI (Forced Ocean Sea-Ice experiments) experiment. Surface atmospheric forcing for both the global CESM FOSI and the regional ROMS downscaling simulations is from the JRA55-do reanalysis dataset. The purpose of this downscaling simulation is to check the improvements in the Gulf of Mexico sea level and circulation brought in by a high-resolution regional downscaling method and to tune it if needed. Only the sea surface height field (as a 10-day average) is made available now; other fields such as temperature and currents will be added later.

Purpose:

Model simulation to study sea level change in the Gulf of Mexico and the effect of using a high-resolution regional (ROMS) downscaling method.

Data Parameters and Units:

sea surface height [cm], latitude [decimal degrees north], longitude [decimal degrees]

Methods:

Ocean model simulation using ROMS initialized and forced at the lateral boundaries using data from CESM-HR-FOSI global Forced Ocean Sea Ice (FOSI) experiment and using atmospheric forcing from JRA55-do (version 1.3). The model used for FOSI runs is CESM2 and is detailed here: https://www.cesm.ucar.edu/models/cesm2. The model used for downscaling runs is ROMS and details and source code are available from: https://ihesp.github.io/rcesm1/rcesm_arch.html. JRA55-do is available at: https://climate.mri-jma.go.jp/pub/ocean/JRA55-do/.
