Decontamination?


Lawrence <lawrence@...>
 

According to Messages-regular reports:

13/01/04 09:00 End of decontamination nominal SEVIRI images resume.

I rest my case. But I'm still willing to be convinced that I am not
dreaming!

Activities planned for week 02:
There will be an MSG-1 decontamination starting on the 06/01/04.
This procedure will have the following impact on SEVIRI imaging.
06/01/04 from 08:30 until 11:15 there will be no SEVIRI data
available.
06/01/04 from 11:15 until 09/01/04 12:00 only VIS channels will
available with degraded quality.
09/01/04 from 12:00 until 09/01/04 13:15 no SEVIRI data available.
09/01/04 from 13:15 until 13/01/04 09:00 SEVIRI images available
with degraded quality
13/01/04 09:00 Nominal SEVIRI images resume

By the way, have you looked at the IR images? The desert regions
have a higher-than-correct temperature, and there is clear evidence
of inter detector line structure.

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

Cheers,
David

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

Activities planned for week 02:
There will be an MSG-1 decontamination starting on the 06/01/04. This
procedure will have the following impact on SEVIRI imaging.
06/01/04 from 08:30 until 11:15 there will be no SEVIRI data available.
06/01/04 from 11:15 until 09/01/04 12:00 only VIS channels will available
with degraded quality.
09/01/04 from 12:00 until 09/01/04 13:15 no SEVIRI data available.
09/01/04 from 13:15 until 13/01/04 09:00 SEVIRI images available with
degraded quality
13/01/04 09:00 Nominal SEVIRI images resume


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)

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 !)

Douglas.
