Hi Aaron,

WPC changed their files recently and I ran into a similar issue with the regular QPF files.

Here is my current CTL file to read in the QPF files: (note the slight differences in the various variable settings)

Someone was gracious enough in this group to help me fix this issue for my purposes, so hopefully this resolves yours.

Hi All,

I am working with the WPC's 2.5km Winter Probability GRIB2 files and I'm having trouble generating index files and opening them in GrADS.

Open Error:  Invalid variable record

  The data file was not opened.

What's going on here? This should be rather cut-and-dry.
