Circumpolar ROMS climatology
Maintenance and Update Frequency: notPlanned Statement: The ocean model used is ROMS, a primitive equation, finite difference model with a terrain following vertical coordinate system [HAIDVOGEL et al., 2008; Shchepetkin and McWilliams, 2009]. The model is configured with an offset pole and a circum...
