For the record, we have been in communication with Jeremy via our
support system. Jeremy did discover a bug here where the altitude was
not correctly derived in the SkewT JTable when the pressure was
expressed in units of Pascals (instead of hPa). The values were showing
up as NaNs. Sean and I fixed the code by correctly taking into account
This problem was also manifested in the GFS 2.5 degree data where it has
also been fixed.

I am in the process of creating some soundings off of a set of archived RUC

to be created and there is a geopotential altitude display on the cursor
readout, but when I go to the table the Altitude section is a  (or Nan if
I export it to a CSV in Excel) . I checked in the 3d fields and
geopotential height is available in the data.
I have attached an image of the table and sounding if that helps.
Any help/ideas would be greatly appreciated,
