[AAS02-P03] High-resolution global atmospheric data assimilation experiments with an ensemble Kalman filter
Keywords:Data assimilation, NICAM, Satellite Observations, AMSU-A
Data assimilation experiments have been conducted with NICAM-LETKF at 112- and 28-km horizontal resolution with 100 ensemble members. Higher resolution experiment can reproduce the precipitation field well by assimilating precipitation observations. We need to keep improving the physical and computational performances of NICAM-LETKF to increase the resolution and the ensemble size, and to assimilate “Big Data” from the next-generation observations.
