[Datastream #XQI-115437]: unidata imagery data stream



Hi Julia,

The EASTL and EASTS datasets (both hosted by SSEC) require information that
would be specified using the McIDAS 'LOGON' command.  The user ID and project
number that would be specified using LOGON are assigned by SSEC for individual
users.  Access to the data would then be allowed, and the user accessing
the data would pay for the data s/he transferred.

The data in the EAST dataset hosted on unidata2.ssec.wisc.edu is _the same_
as the data in the EASTL and EASTS datasets, but it is available to Unidata
community members free-of-charge.

Again, the realtime GOES-East data in the EAST dataset is the same as the data
in the EASTL and EASTS datasets.

re: question asked in a previous email:
> So, how about EAST in unidata2.ssec.wisc.edu? Is it GOES-12?

Yes.  You can see this in IMGLIST listings:

IMGLIST EAST/CONUS.-3

2463  G-12 IMG      22 MAR 07081  13:32:00    32   87 1-4,6
2462  G-12 IMG      22 MAR 07081  13:15:00    14   72 1-4,6
IMGLIST: done

The 'G-12' field under the Satellite/sensor column stands for GOES-12.

The LDM was installed at CCNY in the past (I worked with Kwan Kong on
this).  I do not know if it is currently available/in use/setup, however.
Receiving the images you want through an LDM feed is the easiest way
to get the data.

OK.

Cheers,

Tom
