The main goal of this project is to develop a state-of-the-art data assimilation system that incorporates near-realtime data with which we can provide the community a high quality ocean state product. This assimilation system consists of an Ensemble Filter applied to GFDL's second generation fully coupled climate model (CM2.1, Delworth et al. [2006]). The ocean component of the coupled data assimilation (CDA) is the fourth version of the Modular Ocean Model (MOM4, Griffies et al. [2004]) configured with 50 vertical levels (22 levels of 10-m thickness each in the top 220 m) and 1° horizontal B-grid resolution, telescoping to 1/3° meridional spacing by 1° near the equator.

This is monthly ocean forcing data, 1860-2000, run #5, from the NOAA Geophysical Fluid Dynamics Laboratory's (GFDL) CM2.1 climate model, specifically: GFDL CM2.1, 20C3M (run5) climate of the 20th Century experiment (20C3M) output for IPCC AR4 and US CCSP. In 2004, a new family of GFDL climate models (the CM2.x family) was first used to conduct climate research. The GFDL CM2.x models have become the workhorse model for GFDL's climate research. They are being applied to topics focusing on decadal-to-centennial (deccen) time scale issues (including multi-century control experiments and climate change projections), as well as to seasonal-to-interannual (si) problems, such as El Niño research and experimental forecasts.

This is monthly ocean model data, 2001-2100, run #3, from the NOAA Geophysical Fluid Dynamics Laboratory's (GFDL) CM2.1 climate model, specifically: GFDL CM2.1, SresA1B (run3) 720 ppm stabilization experiment (SRES A1B) output for IPCC AR4 and US CCSP.
