Re: delayed processing problem

Guy Martin <agm@...>
 

I regularly stop and start MDM, as it is running on an amd 1200 with only 512Mb ram and processing goes to 100% for up to 15 secs, so I can have a freed up machine for other work. When I re-start MDM it picks up exactly where it left off with no problem whatsoever.

Cheers, Guy

Can't explain that one Lawrence, unless the HRPT system is doing
something to the Receiver PC's timing, causing the sequence to go
awry. Noone else has reported anything similar. Files are supposed
to be processed in strict as received order, and you could check
this by looking at the Process.log file.

Another reason for a separate receiver PC where possible.

Do you want the good news or the good news?

the data is not sent with lossless wavelet compression, so all of

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.

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

procedure will have the following impact on SEVIRI imaging.

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)
