HYCOM for the Hawaiian Islands Region 1/25 degree with KPP mixed layer

The Hybrid Coordinate Ocean Model (HYCOM) is implemented for the Hawaiian Islands region at a horizontal resolution of 1/25°. The open lateral boundaries are forced by output from the HYCOM Consortium's real-time global ocean prediction system. The vertical resolution of the regional HYCOM is the same as the global HYCOM: 32 layers in all with the upper 28 layers active in the Hawaii region. For surface forcing, output from a high-resolution (0.056°) regional atmospheric forecast system based on WRF-ARW is used. No data assimilation is included in the regional model at present.

This simulation uses the KPP mixed layer formulation.

This link serves output from one model simulation. It is initialized with the ocean state of the global HYCOM on 1 May 2009.

Original model layer variables are interpolated onto 33 z-levels before being made available on the APDRC server.
