Fine-Resolution Global Sea-Ice/Ocean Modeling and Data Assimilation

The focus of our recent work has been to continue global simulations using the Los Alamos Parallel Ocean Program (POP) model and the sea ice model (CICE), as well as ensemble runs using the Simple Ocean Data Assimilation (SODA) and POP (SODA POP). The primary goal of the former effort is to simulate fine resolution (0.1deg) global ice fields using CICE, obtain measures of their veracity, and then move forward with a global coupled 0.1deg POP/CICE simulation. Sensitivity runs using the less computationally expensive global coupled 0.4deg POP/CICE simulation have also been conducted. In the latter effort ensemble runs with SODA-POP are being used to evaluate the relative impact of using different surface boundary conditions and assimilating different data
