Hybrid Coordinate Ocean Model (HYCOM) adalah model samudra koordinat hibrida asimilasi data isopycnal-sigma-pressure (umum). Subset data HYCOM yang dihosting di EE berisi variabel salinitas, suhu, kecepatan, dan elevasi. Data tersebut telah diinterpolasi ke dalam petak lintang/bujur 0,08 derajat yang seragam antara 80,48°LS dan 80,48°LU. Variabel salinitas, suhu, dan kecepatan telah diinterpolasi ke 40 tingkat z standar.
Konsorsium HYCOM, yang mencakup National Ocean Partnership
Program (NOPP), adalah bagian dari U.S. Global Ocean Data Assimilation
Experiment (GODAE).
Didanai oleh National Ocean Partnership Program, Office of Naval Research (ONR), dan DoD High Performance Computing Modernization Program.
