JAXA-RIKEN Ocean Analysis
JAXA and RIKEN aim to unify satellite data and ocean simulation and create an ensemble ocean analysis product, LORA, by assimilating satellite and in-situ observations from JAXA and various institutions at a 1-day interval in a high-resolution regional ocean data assimilation system, sbPOM-LETKF, developed in RIKEN using the supercomputer Fugaku.
