Re my recent mail about NOAA 18 on Eumetcast, it has come to my attention
that replies had already been sent.   I have now discovered that all my
group mails are taking 12/24 hours to get to me and I was replying to a mail
that was nearly 1 day old.  Apologies for problems caused and I will avoid
any replies until group mail issues are resolved.

Ian.

Ian, thanks for that explicit information. Seems, I misinterpreted the presence
of the NOAA 18 tabs and its listing in the ground station pane. Whatever, it
won't make this weather better...

Cheers,
U.

Ulrich, NOAA18 AVHRR is not being sent through Eumetcast.  Only NOAA 19 and
17 are available.   These are now the two prime satellites with NOAA 19
replacing NOAA 18.

ATOVS data from NOAA 18 is still sent on Data Channel 1 from all the various
stations.

Hope that helps.

Ian.

Hello Ulrich,
currently N18 data are not sent because primary afternoon bird is N19.
So there are only N17 and N19.

David, slight misunderstanding, I guess. I am not talking about the direct
reception of NOAA but via Eumetcast. And even prior to Nov 08, the folders
dont' contain NOAA18 data, just ~17 and ~19.

That should be properly handled by the various local reception stations, I

Folks,

I checked back, and I added end-of-pass notification to the AVHRR Manager
back in December 2006:

Release V1.2.8.124 - V1.2.8  2006 Dec 01

   Add call to AVHRRnotify.bat after each segment ..
   .. command file in the same folder as AVHRRmanager.exe
   .. called with the .HPT filename as a parameter

If non-zero "end-of-pass" delay is set the file will be called once
per-pass after the user-specified delay has elapsed, and a sound
announcement can be made.

Cheers,
David

Hi David,

Initially, you could thought it is a good idea to have a graphical app but if
you are interested to automate the process to concatenate the segments to
"create a regional pass" you probably prefer a script that could be scheduled
with a cron job.
I prefer this way because after create this job I process each pass creating
other products like Multichannel SST, quicklooks, netCDF file...

You could see here an exemple:

http://saidin.cmima.csic.es/ (home page)
http://ers.cmima.csic.es/saidin/sst.html (sst java applet)

I have been monitoring the AVHRR data from the above station in conjunction
with the ATOVS data from the above and Svalbard.  It has been helpful that
both NOAA 17 and 19 are in the Arctic region at the same time just now.

Kangerlussuaq is certainly producing AVHRR data from NOAA 17 and that is
very clearly seen in the 12.53 and 14.33 passes which were not taken by
Svalbard ( it took NOAA 19 ).  However looking at the ATOVS data it is clear
that Kangerlussuaq is taking NOAA 18 at the moment, and Svalbard NOAA 19.
As the satellites are very close  no station can take both, with the
exception of Lannion.

With NOAA 18/19 close and getting closer it may be beneficial for Svalbard
and Kangerlussuaq to share them.

Regards
Ian.

Ian,

There may be some fine tuning to get the delays before data times out
adjusted.  Normally, they will wait a certain length of time before
deciding which station had produced the best quality data for a certain
one-minute segment.  If you discern a pattern after a few days, I suggest
you comment to EUMETSAT.

David

I see that Eumetsat have confirmed that the above station has now been added
to EARS-AVHRR.

I was monitoring yesterday and it is difficult to know on many passes of
NOAA 17/19 as Svalbard and particularily Gander can cover very similar
passes.  However I am not convinced that it is taking all the NOAA 18/19
passes.

This morning for example the NOAA 19 AVHRR pass timed at 09.20 UTC in my
opinion has no data from Kangerlussuaq, only Svalbard.

Welcome to the group, Terry.

Other have commented on the gaps.  If they persist after Kangerlussuaq is
added please speak up.

To get the full ground stations pass listing, try checking and unchecking
either one of the ground stations or one of the satellites.  On first
install, you seem not to get the passes listed.

Unfortunately [EUMETSAT Data Channel 1] is a rather catch all channel, so
you are rather stuck with deleting the other data somehow.  The program
does include the option "Delete Channel 1 data" which you could enable.  I
haven't tested that for a while, though.  If there are other files left
after checking that box, please let me know what they are and I can add
them to the "not wanted" list.

By the way, for future compatibility I would suggest pointing the received
data one level down:

____________________________________________
[EUMETSAT Data Channel 1]
target_directory=received\Data Channel 1
____________________________________________

and changing the AVHRR Manager setup accordingly.  You never know when you
want the other data such as DWDSAT.

The images can be truly stunning, as you point out!

Cheers,
David

Hi all

I'm hoping someone might be able to answer some basic questions. I've got AVHRR
Manager working & collecting images - I've been impressed by some stunning
images today for example, & have seen missing sections in northbound NOAA 19
images which others have mentioned. I'm using the time-limited evaluation
version & I am puzzled by the "Ground Stations" page being largely blank. There
are no passes listed and the "Kepler status" lines only read NOAA17... etc. The
program seems to be referring to the Keplers I have loaded in.

I would also like to know how I can limit the data to receive only the files I
need for NOAA images. I have used this entry in recv-channels.ini

[Eumetsat Data Channel 1]
target_directory=received

but it rapidly fills with data which I don't think I need (no other channels are
active at the moment).

I would appreciate any constructive comments please!

Thanks

Thanks for the conformation - I was beginning to wonder as I had to restart

It's run OK since then apart from these 'joins' and I see, a strange

Yes I have seen that as well John.  As you say it appears to be an issue
with segment selection where two ground stations are covering the same
segment and one is at the edge of its limit. Probably a computer issue.

I am not sure if Kangerlussuaq has started yet as the latest AVHRR station.
It was due to come on line today, but being fairly close to Gander and
Svalbard it can be difficult to judge.  I personally do not think it is
active yet.

I am using my old back-up computer ( 6 year old ) today but unfortunately it
looks like my HD is packing up on it.   I have been doing some maintenance
on my Windows 7 Dual core and will be glad to get it back into service later
this evening.

Further to my last email the orbit for N-19 was 02948 - not as I stated
(which was a N-17 orbit number).

I had another small gap across the UK on N-19 orbit 02949 recently.
