Goals

  • This study develops and advances a global atmospheric data assimilation system known as NICAM-LETKF, consisting of the Nonhydrostatic Icosahedral Atmospheric Model (NICAM) and the Local Ensemble Transform Kalman Filter (LETKF). Using the NICAM-LETKF, this study aims to improve NWP by assimilating satellite observations such as GPM/DPR and AMSU-A radiances. In addition, this study improves the NICAM-LETKF system for a long-term stable operation.
  • 全球非静力学大気モデルNICAMに局所アンサンブル変換カルマンフィルタLETKFを適用したNICAM-LETKFシステムを開発し、GPM/DPR降水データや、衛星マイクロ波放射計AMSU-Aの輝度温度データを同化することで、数値天気予報を改善する。また、実用化に向けて重要となる長期間安定動作のためのシステム開発を行う。
