Re: IODC changes today!

Ernst Lobsiger
 

Hi,

those who use my PyTROLL/SatPy Kit 3.0 will have to edit a few things in the MSG1.py script(s) for MSG2. Yo may also want to add an xmsg2 tmp directory and a Meteosat-9 image directory. Don't forget to adapt full disc area 'seviri_iodc' in ..../pppconfig/areas.yaml where the central meridian lon_0 changes from 41.5 to 45.5 degrees East. Goodbye MSG1.

Regards,
Ernst


IODC changes today!

IODC changes today!

There are beta versions of my MSG Data Manager, MSG Animator and GeoSatSignal
software available which should handle the new IODC data from 45.5 degrees, due
after 09:00 UTC today.

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

The only issue I've seen is that you may need to ask the MSG Data Manager to
recreate any active Detail images. Just click on the channel thumbnail and
select the detail image number. Likely you will only see this if you use the
-Detail:<n> command line parameter to start the MSG Data Manager. Automatic
updates to the MSG Animator for IODC data are not yet coded.

https://www.eumetsat.int/meteosat-9-takes-over-IODC-service

Please report any issues to the SatSignal group:

https://groups.io/g/SatSignal

Cheers,
David

Hi,

A nice image of a cloud free Svalbard. (NOAA-20 image Natural colors)

Re: NWC 'Cloud Types' on EUMETCast

Ernst Lobsiger
 

Graham,

there is no super simple solution. You need some minimal data manager for that. This program must recognize the file patterns and read out the start dates that is part of the filenames. The problem is somewhat complicated by the fact that some satellite files do not use YYYYMMDD but YYYYDOY (DayOfYear). Then the program moves or copies/deletes the files into your MountPoint/Channel/YYYY/MM/DD structure. As a byproduct not used or wanted files are deleted. Under Windows Hugo has long had his EumetCastWatcher as EUMETCastView "preprocessor" for that purpose:

https://hvanruys.github.io/eumetcastwatcher

AFAIK now also called DirUpdate

https://github.com/hvanruys/EumetcastDirUpdate

Starting with Hugo's ideas I have written a simple GNU/Linux CLI C-program (using mc and gcc) that does the job. I moves the files from my RAM-Disk (where they arrive in an /opt/Channel/segments structure) to HDD (into /srv/Channel/YYYY/MM/DD/segments) with copy and delete as these are two separate file systems. Alan Curnow has written his own graphical C++ solutions for Windows 10 and a CLI C++ program under GNU/Linux. Take it as a homework to write your own solution along the lines of Hugo's published work.

Good luck,
Ernst

Hi Ernst

My Sentinel3 data is just going into two directories E2H-S3A-02 and E2H-S3B-02 on my /srv/data/eumetcast/hvs-2/ E2H-S3A-02 and the same for  E2H-S3B-02 on my Linux receiving PC

What do I need to do to get them sorted into Year/Month/Day like your data

Kind Regards

Graham


Re: NWC 'Cloud Types' on EUMETCast

Manu,

well done. You managed 10 passes with 16GB. My 24GB receiver also uses memory for a RAM disk + other PyTROLL processing in the background.
I mentionned Aitoff as a similar pseudo conic projection some posts back. It turns out that pycoast has a problem with parallels. So don't waste your
time with trying to setup an Aitoff area in areas.yaml. What works rather well and without gaps is 'scanice' (Scandinavia and Iceland) as distributed.

Cheers,
Ernst


Re: NWC 'Cloud Types' on EUMETCast

Manu
 

Mission successful but only as a ran=60 setting.
 
With this setting my 16 GB RAM was used up to 100%!

Hi Ernst

Thanks I will try those tomorrow hopefully

Kind Regards

Re: NWC 'Cloud Types' on EUMETCast

Graham and Manu,

speaking of GSHHG levels

https://www.soest.hawaii.edu/pwessel/gshhg/

here is a little pycoast secret. If you just set level a number like 6, then you might note
that pycoast will draw levels 6, 5 , 4, 3, 2, 1. But pycoast accepts level lists like [1, 6]  !

Cheers,
Ernst


Re: NWC 'Cloud Types' on EUMETCast

Ernst Lobsiger
 

Graham,

well done! Aitoff is nice as well. But you have to make an entry in areas.yaml first.

https://proj.org/operations/projections/aitoff.html

If you miss Antarctica then set coastline level to 5 or 6 (see GSHHG soest page).

Ernst

HI Ernst

Just tried this and got a lovely image similar to yours

It used 35% of my available ram

Kind Regards

Graham


Re: NWC 'Cloud Types' on EUMETCast

Ernst Lobsiger
 

Graham and Manu,

so far so good! If you have monster RAM (Graham 128GB!) then try 'moll' with the same POI as 'ortho'.
As I said before I "only" have 24GB of RAM and my record before heavy disk swapping is 10 passes.
You already have 'moll' in areas.yaml. Below I set lon=0 lat=0 ran=60. Who dares to set ran=90 :-)  ?

Cheers,
Ernst

P.S. Such are the blessings of proj under the hood. But you must have all the ERR files of course ...


Re: NWC 'Cloud Types' on EUMETCast

Ernst,

successful tests also under windows!

Hi Ernst

Success - thanks for the help

Graham


Re: NWC 'Cloud Types' on EUMETCast

Ernst Lobsiger
 

Graham,

.... and remembering that you have 1.2km resolution at SSP you could even
increase in 'ortho' your image size to height: 10000 width: 10000 .... ;-)

Ernst

P.S. Don't publish an image of this size on MSG-1 though.


Re: NWC 'Cloud Types' on EUMETCast

Hi Ernst

Thanks I'll give it a go

I have 128Gb of RAM so should be OK :-)

Kind Regards

Graham


Re: NWC 'Cloud Types' on EUMETCast

Ernst Lobsiger
 

Graham,

you will have to add an 'ortho' area to your EMCtools/pppconfig/areas.yaml (if you don't have any yet). I used:

ortho:
  description: Orthographic
  projection:
    proj: ortho
    ellps: WGS84
    lat_0: 20.0
    lon_0: 0.0
  shape:
    height: 1000
    width:  1000
  area_extent:
    lower_left_xy: [-6378137., -6378137.]
    upper_right_xy: [6378137.,  6378137.]

Then I defined a point of interest lon=0 lat=0 and ran=45. I already know that you will want to increase ran
to get more and more passes. My receiver has 24GB of ram and chockes with more than 10 ERR passes ...

Happy hacking,
Ernst

Hi Ernst

Thanks I'll have a look at my files later

Here is my first Sentinel image

How did you get the whole earth image - is it just a case of changing the area to ortho or are more changes needed ?

Its a great image

Kind Regards

Graham
