RIAM Japan Sea assimilation

Japan Sea Reanalysis Fields from Kyushu

The four-dimensional estimates of the Japan Sea circulation are provided for any of those who are interested in them. The data covers the entire Japan Sea (33-52N, 126.5-142.5E) for period from January 2nd, 1992 to November 19th, 2000 (total 3245days) with daily interval. The 1/6-degree, 19-level GFDL MOM (OGCM) was driven by daily ECMWF forecast and monthly inflow and outflow at the three openings. Satellite altimeter data of TOPEX/POSEIDON and ERS-1/2 were assimilated into the model by using approximate Kalman filter and RTS smoother.
