Re: MSG Animator

Thorsten Miglus
 

Ian,

I use MSG Animator with a 4K monitor. It works with a setting of 100 %. See attached screenshot (German Windows).
The maximum width for animations is 3836.

Cheers,
Thorsten

I now have a 32" 4K monitor and I am finding it almost impossible to set it up with the animations I want and it will not allow a width of 3840.

I suspect the issue may be that the recommended DPI is 150% ( 100% too small )

My previous monitor 3440 x 1440 was fine but although I increased some text sizes a little the recommended DPI was 100%.

Regards
Ian.

Graham,

1) You have to indicate the Point Of Interest (POI, I added 'Switzerland' and 'Isle Of Man' in my scripts).
It's easy to find the needed latitude and longitude of the POI with google earth or something similar.
Make sure you get data from there. EARS region coverage for some sats, worldwide for other sats.
My scripts find the closest orbit that passed near the POI. There is always one day and one night pass.

2) Reproject the data to the area. You might have to invent your own projection (see my area.yaml).

3) If you want/schedule the data from today make sure those are already received via EUMETCast.

Hope this helps
Ernst

Hi Ernst and Christian

Thanks for the reply

I have one further question

With the polar orbiting satellites they are picking up the orbits that include the UK . If I want the preceding orbit i.e Central Europe and Scandinavia or the following orbit over the Atlantic

How do I do it - I am assuming it might have something to do with swath and the resampling areas . I have tried this

    proj = 'euron0250'
    nscn = scn.resample(proj)
    nscn.save_dataset(composite,imgdir+'/Suomi_PPP-Orbit_'+str(orbmax)+'-'+
                     'DayTime-'+Yea+Mon+Day+'-'+composite+'-'+proj+'.jpg',
                      overlay = {'coast_dir': 'C:\Tools\gshhs',
                      'color': (255, 255, 0), 'width': 1.0, 'resolution': 'i'},
                      fill_value=0)
but it hasnt changed the orbit

Kind Regards

Graham

Hi Ian,
I recently ‘upgraded’ to a 37” monitor to try and compensate eye debris problems and have also run into a few issues.
Suggestions to reduce the display to 1920 x 1080 didn’t help, and I have tried multiple variations along the lines you mentioned.
I have had to live with a compromise of going for the 1440 option and adjusting the DPI the same as yours. The result is that I get more space but lose some legibility on some prog text.
But Animator runs ok apart from the slight blur on text.

Thanks for the reply James.

With a resolution of 3840 x 2160 you need the main display at 150% on a 32" monitor. I have tried all options to get it to work, but without success so either I don't use Animator or I have an expensive spare monitor !!!

Ian.

Re: Omitting "receive_buffer_size=8000000" from the channels file?

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

David,

IIRC we had a discussion re receive_buffer_size beginning with this post:

https://groups.io/g/MSG-1/message/26902

At that time the default was 4000000. AFAIK the client begins to complain
if it's set too low for HVS (but this may be specific for the GNU/Linux client).
There was a note in TD-15 at that time (didn't check the current version).

Regards,
Ernst
====================================

Thanks, Ernst. I did find some posts but they didn't help. I've not set things lower than the EUMETSAT suggestion, and I've not seen the client complain. I suspect there is a default value, but that the default may be on the low side for EUMETCast operation. Pity it's not documented in the otherwise thorough Help information!

Cheers,
David

as HRV is just one visual channel there is no such thing as a "high resolution colour composite".

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

Has anyone tried omitting the "receive_buffer_size=8000000" in the TelliCast cast_client_channels.ini file, and if so, what effects did you observe? Anything in the log files?

Oh, and this may be old ground, but "receive_buffer_size" isn't documented in the TelliCast help, but a "stream_buffer" parameter is. Both appear to be in the executable file.

Thanks,
David

Re: Pytroll/SatPy for EUMETCast

Christian Peters
 

Graham,

as Ernst said there is no natural color HRV available.
You could try 'hrv_clouds'.

The image you attached is a colorized HRV image, not implemented till now in SatPy.

Regards,

Christian


Re: Pytroll/SatPy for EUMETCast

Ernst Lobsiger
 

Graham,

as HRV is just one visual channel there is no such thing as a "high resolution colour composite".
HRV can be used to "sharpen" composites. Some such things are found in the seviri.yaml file.
You will also have to resample the scene (1km + 3km resolution) and project to a nothern area.

You might also want to google for "SatPy HRV sharpened composite" to see what others do.

Regards,
Ernst


Re: Pytroll/SatPy for EUMETCast

Hi

Can anyone tell me if it is possible to get a high resolution colour composite of just the northern HRV image using Python

I cant seem to find one that will give me an image like the one attached (this is not the full resolution image)

Kind Regards

Graham

Ernst, just to confirm that I have started the install using your HOWTO txt file and so far thanks to your detail and clarity all seems to have gone well despite the huge learning curve !

However I am treating this as a learning project and so proceeding slowly and deliberately. I also have other things on at the moment.

Just wanted to let you know that despite silence at this end I am having a go with slow but good progress and to say thanks again for your efforts.

Regards,
Douglas.


Re: TP 1 data rate.

David J Taylor GM8ARV 🏴󠁧󠁢󠁳󠁣󠁴󠁿 🇪🇺
 

David,

Thanks for the link.

I was aware that there was a 'new' update for Tellicast and a new EKU available but had forgotten about it.

Reading it again suggests that you can continue to use the 'old system.'
Which is probably why I did nothing and forgot about it.

However EUMETSAT no longer support the older version of Tellicast software.

So, without bothering Ops at this time, what is the advantage(?) of 2.14.5?
And the advantage(?) of the new EKU.

I thought all of us with old EKU's would be supplied with a new one - but this seems not to be the case?

Regards,
John.
=====================================

John,

I think that if you break your eToken it will be replaced with a new model (requiring a software update, of course).

I recall (vaguely) that newer versions of TelliCast may require the newer eToken. Other than that it was updates and fixes. At one stage TelliCast was updated for some of the new data, but you'd have to search back through the group archive for more info. There is a search function. Or use the Internet!

David

77 Mbps at the IP level.  Same for TP2.

that's quite more in depth information...I will withdraw as your posts are more scientifically sound. :-D

Then you look in the *generic* visir (Visual Infrared) that may be used by different sensors in part.
visir may also be a remnant of early Satpy development. As some kind of germans say: It it wi et it.

Graham,

this channels are no channels from the MSG satellite, it's computed NowCasting data as I understand from MSG or Metop etc.)
You need additional files to extract this CTTH channels, I think like :

https://navigator.eumetsat.int/product/EO:EUM:DAT:0060?query=CTTH&s=simple
