Robert,

Do you want the good news or the good news?

- no, it is not a one-off, although the weather does need to be
clear!

- no, you shouldn't get as good as this next summer, you should get
BETTER! Why? Well, that image was made back in the bad old days
when the HRV data was transmitted with lossy JPEG compression. Now,
the data is not sent with lossless wavelet compression, so all of
those nasty JPEG artefacts will be gone!

You can look forward to even better images from MSG-1 next summer
than you had last summer!

Cheers,
David

Quoting Alan Sewards <alan.sewards@computer.org>:

Folks,
If you fire up GSS in Fires Job, load ch12 for today 040111 at 0915, and
navigate to long 12.3E, lat 12.3S, you will find a very interesting scene.
In the middle of a sun glint, there are a number of patches (some small
islands) showing the red of fires. I wonder what the phenomenon is here. It
must be some form of specular reflection, to produce the apparent
temperatures necessary for declaration of a fire, but what is producing the
reflection , particularly on land?
There are similar effects almost every day. Last Sunday two complete small
islands off the coast showed up as bright red.

Re: UK MSG receotion licenses.

All,

I have now received three notifications of non arrival of UK licenses when
users have been registered with EUMETSAT for some time.
If there are any more of you out there, please drop me an e-mail off group
with your details - name and address and I'll speak to Colin about it when he
gets back.

Regards,
John Tellick.

David's image of the UK - recommended in response to a request for example
images - was captured and processed in July. London, Birmingham and the
Manchester conurabation were visible in this image. Is this a normal image,
routinely achievable in summer illumination, or was it in any sense a one-off?
I ask this because I have a similar HPRT image from around the same time and
although the latter is better (Chester is visible), the MSG-1 image bears
comparison with it.
It will be great if we can normally expect to acquire images like this in the
summer - when the sky is clear that is!

Yes, I work in a school, as an IT Manager not a teacher, and I am currently trying to enthuse them in MSG-1. To do this I have made a simple web page that will produce a choice of four animations full screen in IE6. This available on the school intranet only but if you want the code I can send you the complete page off list.

Cheers, Guy

By the way, have you looked at the IR images? The desert regions

of inter detector line structure.

I, too, am grateful to have even these images back, though!

Yes I have noticed David, but also very interesting is the channel 9
animation of this where you can see the problem being slowly rectified.
I must say given what we saw during IR calibration many months ago I
expected more widespread problems.
.......... and the increased bandwidth for channel 3 seems to be paying real
dividends. All 15.00 UTC FSD just about in (GOES 10 completing) within an
hour, and dare I say it no problems with Meteosat 5 since the bandwidth
increase.
Excellent and thanks Eumetsat. (and David of course !)

Yes that is the end of the entire decontamination process including the
recalibration period etc but if you look at the whole message :-

The third last line indicates that from 13.15, 09.01.04 SEVIRI images
available with degraded quality. Two lines before that makes it clear that
from 06/01/04 (11.15) until 09/01/04 (12.00) only VIS available, and the 75
mins gap between the two, all off, in preparation for start of all data.
(Line references may be out depending on peoples line length settings)

Lawrence, I presume that until the detectors and the rest of the
satellite stabilise at normal operating temperatures, the thermal
calibration won't be correct. Plus presumably there may be gases
around the satellite etc. Perhaps Eumetsat need to confirm the
calibration as well?

David

No, check the Regular Report message Lawrence. Data (ie vis) would stop at
12.00 and all data return at 13.15 UTC today (9th). In fact as David
pointed out it ran about 1 hour late. 13th January (09.00) before
calibration can be guaranteed. As expected some images (see ch 09 for
example) are not nominal at the moment.... but great to see IR back
particularly for this time of the year at northern latitudes.

MSG-1 SEVIRI image data is now back to all 12 channels as of the

until Tuesday, Jan 13th.

my mistake probably, it must be RH 8. That PC is the only one I ever

the RH version, apologize.

what do you suggest to me ??
oh well, it really depends on your familiarity with recompiling Linux
kernels and loadable modules. If you are not too comfortable in
doing that, I am afraid this will be a pretty complicated job for you.

Make sure that the kernel you are running on your RH is the correct
version, and likewise for the gcc compiler. I did not have to
recompile the kernel when I did my tests.

thanks again

Edward,

a few months ago I did successful tests under Linux, running
Tellique
with a WinTV Nova DVB card, and the sharing the "received"

under Samba, so I could decode the files with David's software.

I sure can help you in your tests, but bear in mind that I am not
sure about how the Linux version of Tellique supports the eToken
Pro
USB token. So this all might be a temporary solution, but it's
definitely worth trying.

In order to set up the DVB data reception, you have to follow the
instructions found on http://www.linuxtv.org/

The LinuxTV 1.0.1 driver supports the SkyStar2 PCI card, but not
the
USB version. Please read all the docs included with the driver and
load the different modules in order to have Linux recognize the
card.

You might not need to recompile the kernel, I didn't have to under
RedHat 8.2 at least.

You will need a few modules for the LinuxTV
driver, all is well documented in the driver docs.

After that, I will share with you the tricks I had to do in order
to
have Tellique work properly under Linux. But I will need to reboot
the PC to browse my config files, so I will do it another time.

Meanwhile, let me know when you'll be OK with the LinuxTV driver.
