A family of 5 grids in fastar format are included in the directories.
These grids are in fsgrid, unformatted, but attention must be paid to the record length in L3, L4, and L5.
These grids were generated and made available by JAXA.  
JAXA POCs: Dr. Takashi Ishida (ishida.takashi@jaxa.jp) and Dr. Mitsuhiro Murayama (murayama.mitsuhiro@jaxa.jp)
