Folks - on a slightly different topic from normal: are we yet able fully to
exploit the advantages of MSG-1 over its predecessors? For example, today's HRV
animation shows fascinating cloud movements across Europe and the Eastern
Atlantic (quite beautiful to watch, too). A formless blob moves up over the
Irish Sea and the Welsh coast - how do I know if this is cloud or fog? Actually
I know it's cloud because I can look out of the window - but supposing it was
in the North Sea?
Is anyone working on this kind of question yet - or it premature until EUMETSAT
gives us more info?

Animator queries

James Brown <james@...>
 

Hi,

Just a couple of little oddities to ponder.

1. Sometimes when I start Animator and select update it updates all 5 of the animations at the same time. At other times it allows me to do them one at a time. Is there a consistent reason for this I wonder?

2. I've noticed that on the visible Northern hemisphere Ch2 animation there are times when the brightness increases quite markedly for a few frames, particularly for the middle-range grey levels. I'm wondering if this is a transmission error, as it appears to be there whether I have histogram selected or not.

Cheers,

James

David,

I couldn't agree more with you. I have found that loading anything that
requires the computer to restart ( MS updates new program etc. ) leaves me
with problems with the card and Tellique, although I suspect its the card
problem that affects Tellique. A full reboot gets everything back fully
working.

Regards

Ian.

There is something in the hardware or the two pieces of software that
doesn't reset cleanly - I have made much more use of the hardware reset
switch since I had the DVB then ever before (in years of running Windows
2000).

Did you also get a missing 0845 cycle yesterday.
Yes, I did.

My log shows last file received for 0830 cycle was at
08:47:38 HRV segment 24.
thence..
08:48:21 Key 65477 expired
08:48.42 Key 65481 expired
08:49:12 Key 65483 expired
08:59:35 Received new key 65516
Return to reception of 0900 cycle.

I have also noticed this missing segment behaviour if I hot swop dishes.
The only way I found to resolve this is a switch ON/OFF, restart has no
effect and of course no hot swopping.

Solar outage was more severe yesterday a quality drop from 70% to 48%
and SNR from 10.8 to 9.0.

I forgot to watch mine yesterday....

Must try harder today!

It does make you wonder, David. Tellique log file for the period
has a lot of ended/interrupted after file transmission reports
with ..files missing/incomplete. So it certainly was being picked
up. The DVB system appeared to be working perfectly, so it does
sound very similar to your own experience, except I can point to a
specific event of my own doing.
Lesson well learnt.
I was showing Ian something, as he was visiting, so maybe
sabotage !!!!

Thanks
Douglas.
Well, this morning from about 0515 UTC onwards I seem to be having a
similar problem, so I'll reboot. There were some Security Updates
pending in any case. The missing segments were correlated with log
file inconsistencies.

I'll send a little program to look at [copies of] the log files....

Cheers,
David

Glad to see you have now solved the problem. I wonder if I had the
same issue when I had all the unexplained missing segments? It
might also be interesting to check the Tellique log file.....

Missing Segments

Douglas Deans <douglas@...>
 

Peter (and others).
Problem resolved, and a lesson learned.

This afternoon I accidentally exited the DVB programme instead of minimising
it to the Taskbar. I only realised this when I noticed on my processing
computer that no images were coming in. Having realised my mistake, I
re-started the DVB program (with Tellique still running) and all seemed
well. In fact I have been getting about a 10% segment loss.
I restarted everything in sequence and now all is fine.... another step on
the learning curve. Do not go near the DVB program and if you do, restart
in the correct sequence ie. DVB with Tellique off, followed by Tellique on.
Why it behaves in this strange way is anyone's guess, but it does.

Thanks again for your report Peter without which I would have continued
assuming Eumetsat problems, instead of looking a little closer ! (My
apologies to Eumetsat for wicked thoughts !!)

Regards
Douglas.

Missing Segments

Had visitors today and just back to the computer. I take it others are
seeing quite a number of missing segments since this afternoon. Seem to be
widely scattered.

Yes, it did the best it could. I was half hoping those missing

To my mind it acted perfectly. Those segments were never sent. I know you
are very talented but even you can't fix that !

David,

I thought that the program handled the missing segment problem at 11.30 UTC
pretty well. I know this is probably wrong, but the impression I got was
that the program waited to see if it was a late segment problem and at a
particular point in the next cycle decided the segments were missing and
saved the images on the 11.30 cycle accordingly. Seems a very reasonable way
of dealing with the problem.

Regards

Ian

Data Manager

Ian S Deans <ian@...>
 

The new beta Data Manager was certainly put to the test this morning. At
about 10.06 UTC only slightly more than half the 9.45 cycle appeared to be
in, yet by just after 10.10 it had completed the five HRIT images I take and
very quickly started to process the 10.00 cycle. The program is clearly able
to catch more than a few late segments and is working superbly.

Regards

Ian


Solar outage.

Peter Benney <tugboat@...>
 

During yesterdays period of solar outage outage I monitored the Setup4PC status tab and watched as the quality reduced from 70% to 60% and a normal SNR of 10.8 reduced to 9.6. BER was unaffected. WxTrack tells us peak outage is on the 11 Oct so we may well see a more significant disturbance to the signal.
