Hi!

Three segments of METOP-C are involved.

METOP-A and METOP-B are O.K.

Hartmut,

as your MRTG graphs on David's page seem not to be UTC could it be that this started with the change to summer time?
In other words are you sure your image processing is scheduled in UTC? If not just try to make the images one hour later.

Best regards

Hi!

No, the time is correct. But I had a little typo, In my last mail: 12:00 UTC instead 11:00 UTC.

The images are captured with UTC+1 regardless of DST.  

I started the Job (METOPC)  this time (14:54) again with the same results.

Timestamp of the new pic is 11.4.2021 14:54. (local MESZ).

Any suggestions?

Regards

Hartmut

Briefly, I reported it, and the fault was fixed, and I was informed it had been fixed.

I noted that it had re-appeared in my daily report to EUMETSAT today, but as yet I've had no response to that. Although it's holiday time and the virus, which may delay a response, I think that anyone experiencing the problem might like to provide a report to EUMETSAT. I guess the more information the better.

Cheers,
David

Ernst,

I didn't get an official answer (other than a thanks, and a note that the problem was fixed) but your observation that the data flow exceeded the maximum was correct.

I'll do.

The HVS-2 loss:
As yesterday only HVS-1 was mentioned I didn't check HVS-2.

About S5P I can't report on HVS-2 as I receive the whole S5P-stuff and
others via terrestrial EumetCast.
On HVS-2 I receive OLCI, SRAL and SLSTR.
I just checked and only had one single missed/recovered OLCI file back
on March 31st.
No losses nor missed yesterday.
Maybe lower sat-signal and I don't see it as I run a 1.8m and one 2.0m
dish ?
Have a happy easter
Heiko
Thanks!

I guess a stronger signal /could/ be less susceptible, but I think it unlikely in this case. We've seen this before during recent EUMETSAT changes.

Happy Easter!

Heiko,

I suggest reporting that to EUMETSAT (although Ops are on holiday). I take all channels, so I can't report on individual channels. Interesting that both EPS-3 and EPS-5 have a lower bandwidth (12000 kbps) than the highest rate channels (16000 kbps). That may be significant. Data from:


https://eumetsatspace.atlassian.net/wiki/spaces/DSEC/pages/700055570/Channels+and+Packet+Identifiers+PIDs

[Why isn't this a EUMETSAT site?]

Here, although there has been an anomalous missed & recovered TelliCast packet loss rate (like when too much data was pushed through) actual lost packets were very low, and possibly just one lost EUMETCast file on HVS-2. No losses on HVS-1 (all channels) or on BAS (the channels I take). The HVS-2 loss:

MSG:2021-04-01 11:46:27.772:Missed parts of file `S5P_NRTI_L2__AER_AI_20210401T094109_20210401T094609_17961_01_010400_20210401T114235.nc' id 6065b237001ae87a from channel `E2H-S5P-01'

and this was also reported at Arne van Belle's station.

David
