Rosie, Dee, Jay, and Jerry,

Regarding problems seen serving the GOES-East/West datasets off of
unidata2.ssec.wisc.edu after I upgraded McIDAS from a 32-bit build of
v2006 to a 64-bit build of v2007:

Well, my assumption was incorrect.  When I switch back to the 32-bit build
of Unidata McIDAS v2006, ADDE serving of EAST data starts acting as it
should.  For instance:

v2007 gvaradir listing:

IMGLIST EAST/NH.-1
Image file directory listing for:EAST/NH
 Pos Satellite/         Date       Time      Center   Band(s)

     sensor                                 Lat  Lon
 --- -------------  ------------  --------  ---- ---- ------------
9970  G-12 IMG      15 SEP 07258  07:15:00    14   72 1-4,6
9972  G-12 IMG      15 SEP 07258  08:15:00     4   80 1-4,6
IMGLIST: done


64-bit v2007 gvaradir listing:

IMGLIST EAST/NH.-1
Image file directory listing for:EAST/NH
 Pos Satellite/         Date       Time      Center   Band(s)
     sensor                                 Lat  Lon
 --- -------------  ------------  --------  ---- ---- ------------
 426  G-12 IMG      25 SEP 07268  22:15:00    22   71 1-4,6
 425  G-12 IMG      25 SEP 07268  21:45:00    22   71 1-4,6
IMGLIST: done

So, I am led to believe that there is something wrong either with
the v2007 version of gvaradir/gvaraget or that building 64-bit
executables is the culprit.

NB: the symptoms of the problems seen with the 64-bit version of v2007
are that the directory listings are temporarily inverted from what
they should be: an IMGLIST/NH.-1 listing should show the newest
data in the dataset (which it does using v2006) not the oldest (which
is what happens with the 64-bit v2007 build).

I will rebuild v2007 in 32-bit mode to see if this makes a difference;
I will keep you posted on what I find.

Cheers,

Tom
