You're welcome, I'm glad you're finding ncdump useful.

If you happen to have IDL, you might find Tom Woods' IDL procedures
useful for this:

  ftp://laspftp.colorado.edu/pub/see/software/idl/netCDF/readme.txt

Another possibility, if you don't need to interpret the satellite
navigation, is just using a generic netCDF utility such as ncview:

  http://meteora.ucsd.edu/~pierce/ncview_home_page.html

or ncBrowse:

  http://www.epic.noaa.gov/java/ncBrowse/

There are many other generic systems that can read and provide a
visualization of netCDF data described here:

NOAA FSL's AWIPS system can read and display satellite images
represented as netCDF files, but that is a large system that you would
not want to install just for this purpose, and it would require that
the TIMED images were stored using the same netCDF conventions AWIPS
expects:

  http://www.nws.noaa.gov/mdl/awips/aifmdocs/sec_4_e.htm

I just mention it in case you happen to already have access to an
AWIPS system.  Finally, there is GEMPAK, which is also able to read
AWIPS-formatted netCDF satellite image data:

  http://www.unidata.ucar.edu/packages/gempak/

This is another fairly large system, and would only be useful if you
verified that the AWIPS conventions were used.

answered when I am away from my email ...
