Generic Fortran modules for LETKF and its implementations for specific models (e.g. Lorenz-96, Speedy, WRF...).


LETKF implementation for a regional atmospheric model SCALE-RM.


SEIB-PF can assimilate Leaf Area Index with SEIB-DGVM (Spatially Explicit Individual Based Dynamic Global Vegetation Model) using Particle Filter.

Precipitation nowcasting

Programs for our precipitation nowcasting system (RIKEN nowcast). We use a kinematic approach based on an advection equation and a data-driven approach based on motion of precipitation pattern. To improve the system further, we are investigating a deep-learning-based algorithm.
