“KIAPS(Korea Institute of Atmospheric Prediction Systems) has been developing a new global NWP model(KIM, KIAPS Integrated Model) as well as an advanced data assimilation system since 2010. Science 2013, we have implemented and investigated Local Ensemble Transform Kalman Filter (LETKF) data assimilation system to a cubed sphere model of NCEP CAM-SE, while developing KIM. It would be very easy to replace the model by KIM when released because the grid structure between CAM-SE and KIM is same.”
