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.

Cheers,

Hi David

I suggest reporting that to EUMETSAT (although Ops are on holiday).
I'll do.

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

id 6065b237001ae87a from channel `E2H-S5P-01'
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.

Cheers,
David

GOMS3 support in the MSG Data Manager beta

Folks,

For those of you wanting to try the recently released GOMS3 data on
EUMETCast there is a beta update to the MSG Data Manager here:

ย ย ย  https://www.satsignal.eu/software/beta.htm

I am not currently happy with the IR4 data which appears to have a
double or out of focus image (not caused by my program as far as I know)
and the Visible channel seems to have the excessive gain issue which was
present on GOMS2 visible.ย  IIRC it was far too dark (full scale being
far less than 100%) and EUMETSAT tweaked their processing to compensate).

Reports welcome.

Cheers,
David
MSG Data Manager beta updated today with a better gain setting for the visible channel.
Sample using GeoSatSignal attached.
Cheers,
David
===============================================================================

Very nice David. Many thanks.

Regards,
Douglas.
