HyCOM
From Wikipedia, the free encyclopedia
The Hybrid Coordinate Ocean Model (HyCOM) is an open-source ocean general circulation modeling system.[1] HyCOM is a primitive equation type of ocean general circulation model. The vertical levels of this modeling system are slightly different than other models, because the vertical coordinates remain isopycnic in the open stratified ocean, smoothly transitioning to z-level coordinates in the weakly stratified upper-ocean mixed layer, to terrain-following sigma coordinates in shallow water regions, and back to z-level coordinates in very shallow water.[2] [3] [4] Therefore, the setup is a “hybrid” between z-level and terrain-following vertical levels. HyCOM outputs are provided online for the global ocean at a spatial resolution of 0.08 degrees (approximately 9 km) from 2003 to present. HyCOM uses netCDF data format for model outputs.[5]
