20040121: Unidata-Wisconsin data stream image sectors (cont.)



>From: "Kevin W. Thomas" <address@hidden>
>Organization: OU/CAPS

Hi Kevin,

>My line says MCIDAS on it, not UNIWISC.  Will that cause a problem?

No.  UNIWISC is now the primary name for the datastream, but MCIDAS
is still recognized.

re: the machine you are requesting the UNIWISC stream from has a
limited request in its ~ldm/etc/ldmd.conf file

>I'm wondering if this is possible.  Mark...any chance that some of the
>satellite data is being filter out?

Kevin, the way you can test this for yourself is to run a notifyme
command for UNIWISC pointing at stokes:

<as 'ldm'>
notifyme -vxl- -f UNIWISC -o 10000 -h stokes.metr.ou.edu

'notifyme' will tell you want stokes has ingested.

re: the pqact.conf entries you are using for decoding the UNIWISC data are
not processing all of the imagery

OK, here we find the problem:

1) change Q1 to Q.  (Q dot).  The notifyme listing you get above
   will show you that the header changes based on the time of the hour.
   Your pqact.conf entries are only decoding the images that are marked
   with Q1; the other images are marked with Q3.

2) you don't have entries for the short IR (3.9 um) and long IR
   (13.3 um for GOES-East and 12.0 for GOES-West) images that are
   now in the datstream

re: So, if your machine is kiowa.caps.ou.edu, I would say that there is
a problem in your decoding of data.

>If that is the case, then maybe MCIDAS no longer matches all the satellite
>data.

No, UNIWISC and MCIDAS are equivalent as far as LDM-6 goes.

>Can you tell me what your pqact.conf decode entries look like?

re: run notifyme
>notifyme -vxl- -f UNIWISC -o 10000 -h stokes.metr.ou.edu

I have it running.

re: 1) change Q1 to Q.  (Q dot).  The notifyme listing you get above
will show you that the header changes based on the time of the hour.
Your pqact.conf entries are only decoding the images that are marked
with Q1; the other images are marked with Q3.

That sounds like it.  When I configured it, the web page that I grabbed my
sample entries must have had Q1.

re: 2) you don't have entries for the short IR (3.9 um) and long IR
(13.3 um for GOES-East and 12.0 for GOES-West) images that are
now in the datstream

I only take in what is being used.  Now that I have *lots* of disk space,
I may add them.

re:  ldm-mcidas-pqact.conf.all
http://my.unidata.ucar.edu/content/software/mcidas/mcidd/ldm-mcidas-pqact.conf.all.html

So that is where that page went.  The one that I had bookmarked was
.../ldm-mcidas-pqact.conf.html, which no longer exists.

Thanks for the assist.

I've confirmed that this fixes the problem.

Thanks for your help.

I have in my ldmd.comf:


request         MCIDAS          ".*"    unidata2.ssec.wisc.edu


and for downstream:


allow           ANY             ^[a-z].*\.caps\.ou\.edu$

Mark...

Tom at Unidata helped me figure things out.  I had to make a small change to
my "pqact.conf" file.
