Luis,

Sorry I couldn't get to this a couple of days ago, but I was in the middle
of selling my house and moving.

OK.

You are already getting these images.  While pointing at atmos.uprm.edu
(DATALOC ADD RTIMAGES atmos.uprm.edu), I created the following listings
that demonstrate that you are receiving the Mollweide image products
in the Unidata-Wisconsin datastream:

>and all the weather text for SJU (he gave me an example of what he wants
>http://www.srh.noaa.gov/data/sju).  Is it possible to get those?

You are already getting these also.  If I remember correctly (my login
to atmos no longer appears to work), you are requesting all of the DDPLUS
and IDS data (the volume for this is low), and are feeding both of
these streams into the McIDAS-XCD process in ~ldm/pqact.conf:

DDPLUS|IDS      ^.*     PIPE
        xcd_run DDS

The textual products are contained in the RTWXTEXT dataset and are all
listable using the WXTLIST application of McIDAS.  Here are a couple of
examples:

First, here is the listing one gets from the URL you sent:

This product is an upperair listings for San Juan, TJSJ.  You can access them
using the WXTLIST application looking at your own machine:

Notice how the value for APRO= is the first three characters of the AWIPS
product header, and the value for ASTN= is the last three characters of
the AWIPS product header:

ABVSJU
\_/\_/
 |  |__ ASTN= value
 |_____ APRO= value

As is always the case with McIDAS, there is more than one way to get the same
information.  Here is an alternate WXTLIST invocation:

WXTLIST WMO=UFUS42 WSTN=TJSJ

In this case, I searched on the WMO product header, UFUS42, specifying
that I want the information for the WMO station ID, TJSJ.

You can tailor your WXTLIST request by specifying more or fewer keywords
on the invocation command line.  In particular, you might want to look
for data for a particular day/time.  How far back you can look in time
will be determined by how much of the TEXT data that you keep on your
system at any time.  The real beauty of ADDE is that if your system
is not keeping enough days of data online (i.e., you are interested in
textual reports for several days ago), you can always point at a different
cooperating server and see if it has the data.

You can find out more on how to run WXTLIST through the online help:

HELP WXTLIST

The good news is that you don't have to touch anything in the LDM setup.
The bad news is that you have to learn how to run WXTLIST :-)

This is very good news indeed, especially considering that Puerto Rico
just connected to much higher speed networking.

I hope so too.  Good luck!

You are welcome.  Please let me know if you run into any problems
figuring out how to run WXTLIST to see the textual data you/Amos wants.

Tom,
   Hi, everything seems to be working fine now.  Thanks.  For some strange
reason, our connection to San Juan got an upgrade this week.  It wasn't
announced, and I still don't know if it's going to be permanent or
anything else about it for that matter.  What I've heard is that it's some
sort of optical line, and that it could be an (OC-3) but nothing sure.
No more connections problem(at least for this week).  Great news.  We have
lost no images all week long.
