Paul,

Right.

Is Gilbert's comment informed by knowledge of your pipe to the internet,
or is it a general warning about the volume of data in NOAAPORT channel's
1 and 2?

>Is there any way to get GOES east and west 1km vis
>images only?

Yes.

>If so, how  do we set that up?

You setup an LDM request line that specifies that you only want the
1 km VIS images.

The headers for the GOES-East and -West VIS sectors contained in the
NIMAGE IDD stream look like:

sat/ch1/GOES-8/VIS/20030113 2215/EAST-CONUS/1km/ TIGE01 KNES 13221
sat/ch2/GOES-10/VIS/20030113 2200/WEST-CONUS/1km/ TIGW01 KNES 132200

There are a variety of regular expressions that would match these
patterns, here is one:

request "*VIS*CONUS"    server.name.edu

Since I already setup you up for NIMAGE data from UNL, your request
line would look like:

request "VIS.*CONUS"    papagayo.unl.edu

You can test this and other kinds of patterns for feed subsection by running
the LDM application 'notifyme' while pointing to your upstream server:

<login as 'ldm'>
notifyme -vxl- -f NIMAGE -o 3600 -h papagayo.unl.edu -p "VIS.*CONUS"

>Were you able to get into climate?

I am able to get onto climate, but I have not had the time yet; sorry.
