June 2010 Subset of R-CESM ROMS Outputs for Free-Run, SSH-Assimilated, and SSH-and-SST-Assimilated Simulations

This is an example subset of ROMS ocean-model output from three Regional Community Earth System Model (R-CESM) Gulf of Mexico simulations used to evaluate Loop Current System dynamics.

Please contact the author ([e-mail]) for access to the complete original/processed R-CESM output archive, and use the following original papers as citations.

The dataset uploaded here includes:

1. Regional Community Earth System Model, R-CESM ROMS output examples: cmpr_*.nc files are representative ROMS ocean-output files from R-CESM. Because the complete R-CESM output archive is very large, only a six-day subset from June 2010 is uploaded here as an example dataset for inspection, testing, reproducibility checks, and demonstration of the file structure.

2. Three simulation types are included and can be identified from the file names:

Files containing "_nature_" are from the NA simulation, which is the free-run or nature R-CESM simulation without data assimilation.

Files containing "_sla_" are from the SLA simulation, which is the R-CESM simulation with sea surface height anomaly assimilation only.

Files containing "_SSHT_" are from the SLAT simulation, which is the R-CESM simulation with both sea surface height anomaly and sea surface temperature assimilation.

3. These files are ROMS ocean-component outputs from the coupled R-CESM system. R-CESM incorporates WRF and ROMS within the CESM coupling framework. The ocean component uses a 3 km ROMS configuration with 50 sigma layers, and the coupled configuration includes a 9 km WRF atmosphere component.
