Dear GrADS users,

I am having trouble opening surface analysis fields from the JRA-55 
reanalysis: https://jra.kishou.go.jp/index.html

When I attempt to open the file, all variables are undefined. I have the 
same issue using OpenGrADS v2.2.1.oga.1or GrADS v2.2.0 from COLA.

I am attaching the provided control and idx files in case anyone is able 
to offer any suggestions.
Here are 2 months of data (I'm sharing as links, since they are larger):

Thanks much,
Andrew
