I created 6-hour precipitation accumulation files from HRRR output using
pcp_combine. When trying to run mode (whether 9.0 or 9.1, didn't seem to
matter), I got this error shortly after invoking:

This is on NOAA's Jet machine. I presume I'm making a mistake, but what?

Below is output from ncdump -h on the forecast file:
