John,

That's what I got from Metop-C yesterday. A big gap as well ...

This is rather relevant at the moment - is it not?

He also said:

You begin saving the world by saving one man at a time; all else is grandiose romanticism or politics.

Food for thought, right now?

No. As it's named it's a backup.
Means if Eutelsat 10A is in trouble or broken the EumetCast service is
provided via
Hotbird 13.

See following citation:
<snip>
in case of an unrecoverable failure of E10A, the EUMETCast Europe
Service will be continued on HB13.

13E is just a backup facility for EUMETCast in case 10E fails. They are testing currently.

Dear EUMETCast-Europe User,

 

Further to our email below, please be informed that the EUMETCast Europe back-up transponder changed from E21B to HB13 on 1 February 2021, as planned.

 

Please find attached the latest version of TD 15 which has been updated with the new official backup satellite parameters for HB13.

 

The EUMETCast web page has been updated accordingly (EUMETCast | EUMETSAT Website), as well as the EUMETCast Knowledge Base (EUMETCast - EUMETSAT Public Confluence (atlassian.net)).

 

As mentioned previously, we plan to perform a test activation of the EUMETCast Europe service on HB13 – exact dates and further details will be provided in due course.

 

Best regards,

Dear EUMETCast-Europe User,

 

EUMETSAT operates EUMETCast Europe in Ku-band via EUTELSAT 10A (E10A). In case of an unrecoverable failure of E10A, the EUMETCast Europe Service will currently be continued on EUTELSAT 21B (E21B) in the 21° East orbital position.

 

As already announced via our Weekly Operations Schedule, starting from 01/02/2021, the EUMETCast Europe restoration (back-up) capacity will be migrated from E21B to Hotbird 13 (HB13) in the 13° East orbital position. This means that from 01/02/2021, in case of an unrecoverable failure of E10A, the EUMETCast Europe Service will be continued on HB13.

 

A test activation of the EUMETCast Europe service on the foreseen HB13 transponders is planned in Q1 2021. During the test, the same data streams will be available on both satellites (E10A and HB13). Further details will be provided in due course.

 

For technical details on Hotbird 13 transponders and downlink parameters, see our web news: Migration of EUMETCast Europe restoration capacity to Hotbird 13 | EUMETSAT Website

 

Please do not hesitate to contact us if you have any questions.

Re: Eumetcastview Europe projection

Hugo
 

Hi Daniele,

I am not aware of a 'Europe projection' in EUMETCastView, but you can make for example a 'Lambert Conformal projection' of Europe  :)
The projection canvas size is independent of the image resolution, so you can take any canvas size you want. The program uses bilinear interpolation for smoothing out the projection image.

Kind regards,
Hugo


Eumetcastview Europe projection

Hello,
does anyone set up a Europe projection for AVHRR or VIIRS with the right resolution, on Eumetcastview? Which parameters do you use? Thanks

Thank you for what you're doing. I'm starting to learn Python in order to be autonomous as much as possible.

Re: Unknown Satelllite Frequency

MZFB@...
 

Thanks Jerry also I forgot to ask in my post and maybe you would know does the GOES satellite emit a chirp by chance? I hear
 the regular digital raspy sound when the satellite is transmitting data but when its not transmitting I hear a faint chirp.  When I move the dish off the GOES compass heading it goes away.
Thanks
Mike

The GOES 16 signal at 1693.0 MHz is the satellite housekeeping telemetry.  The signal is BPSK/RHC.  The BW is 80 KHz.

Ferdinand,

thanks for sharing this. Let others adapt it for Metop-A and Metop-C so we get broader user expertise.
AFAIK Metop-B and Metop-C are in the same orbit app. 180° out of phase. So someone can make a
Metop-X_DAY_stack.py similar to Sentinel-3X_DAY_stack .py to get broad coverage on low latitudes.
And Metop also has data on the night side. What I distributed is named to be a "Starter Kit ..."  only.

pytroll working version of Metop stacked

Ferdinand Valk
 

All,

Attached is the final version of a Metop script that stacks different passes
during a day. Some code was missing to decompress bz2 files, which Ernst was
kind enough to point out.
Please keep us posted of further changes, improvements or innovations.

Best regards,
Ferdinand


Re: Pytroll/Satpy Metop composite

Ferdinand Valk
 

Thanks Ernst.

As usual sloppy reading from my side. Your commented line in the single pass version clearly indicated:

# Decompress all n bestfiles found.

Should have triggered me...

 

The adapted version now works with normal bz2 files. I’ll post it for others to change it to own versions for other Metop sats and/or night versions.

 

Btw, finally snow has arrived here and the heated dish can serve its purpose...

 

Cheers,

Ferdinand

//snipped

 

Ferdinand,

The reader only takes decompressed files. The single pass version decompresses bestfiles[].
For your multipass version you have to decompress goodfiles[]. You must add very few lines:

...
# Get useful info back from timmax
dt = datetime.fromtimestamp(timmax)
orbmax = orb.get_orbit_number(dt)
telmax = dt.strftime('%H:%M UTC')
tfname = dt.strftime('%H%M')

## ------------------------------- BEGIN STUFF MISSING
# Decompress all goodfiles found
for n in range (0, len(goodfiles)):
    filename = goodfiles[n][offset:-4]
    cmdstr = toodrp + '/EMCtools/exefiles/7za x -so ' + goodfiles[n] + ' > ' + filename
    goodfiles[n] = filename
    os.system(cmdstr)
## ------------------------------- END STUFF MISSING

# The blend function actually stacks the passes one after the other

numpass = 0
...

Cheers,
Ernst
