[gradsusr] SDF file does not have any non-coordinate variables

[Charles Seman - NOAA Federal]

Laura,

I don't know if it would make a difference, but one thing to try would 
be to change the order of the dimensions in the variables from (level, 
time, latitude, longitude) to (time, level, latitude, longitude).

Hope this helps,
Chuck
