Hi Mary Ellen,

I don't know about GRADS, but I can tell you that McIDAS has no capability
(meaning ADDE server) for _reading_ satellite imagery in netCDF format.

Question:

- have you tried using the IDV to see if it can display the netCDF image
  you created?

I'm sorry that I can't shed any light on GRADS-related things.

Comment:

- the error shown in the screen shot you attached is:

IMGDISP: AGETSERV failed on exec of ncdfaget

  This is essentially saying that there is no ADDE AGET server for images in
  netCDF format.  This, in turn, means that McIDAS-X does not support displaying
  of images in netCDF format.

  Musing: I was somewhat surprised when SSEC created a netCDF output server but
  did not then build the corresponding server for input (list and/or display).
  I seem to recall that the output server was written so that users could 
convert
  images in AREA format to netCDF so they could be used in AWIPS.

Question:

- do you have an example image that you could send me/make available so I could
  play around with it in the IDV?

  Also, if we had an example image, we could test to see if AWIPS-II is capable
  of displaying it.

Cheers,

Tom
