Re: HRV north.

geojohnt@...
 

Hello Thorsten,

OK, thanks for that.
Gosh, some time ago - I hadn't noticed and wasn't aware of the changes.

I'll obviously have to revert to RSS HRV-N imaging to maintain the easterly coverage area when required.

Best wishes,
John.

to allow for a better coverage of the Azores. The HRV

Meteosat RSS and IODC HRV windows.

Ernst,

I started 1991 with a 286 PC and MS Dos 3.3.
Extending the memory to 16 MB was really expensive.
It was EGA graphics with 16 colours.
Later there was an upgrade to 256 colours.
What a dramatic technical progress since then!

Cheers,
Thorsten

I decided now to go in the direction of Pytroll/SatPy.
It's easier to script and that's what UNIX is all about.

The glitch in the BMP header seems not to be a problem
for David's software or Microsoft Windows Photo Viewer.

And *YES*: UKW-Technik that was the receiver I started
with using a 3m dish for Meteosat and a crossed dipole
for NOAA satellites in the early 1990-ies at my school.

Ernst,

David's software comes with a land/sea mask for every
satellite. I made the LUT some years ago with my
reception station from the German manufacturer
UKW Technik. Then I adapted it for use with David's
Software. The LUT was saved with a 20 years old
version of Corel Photo-Paint.

Cheers,
Thorsten

Appatently you must know what is land and what is sea and
then apply line one or line two of your LUT. This of course
cannot be done by looking at a single VIS channel. As your
image shows nice coastlines as well I suspect there is
something like a bitmap applied which knows what is land
and water. This of course is not how I use a LUT with IM.

What software do you make yout LUT with? I had a closer
look at your *.bmp and AFAIK it has a problem in the 54
byte BMP-header. There is a "uint32_t image_size_bytes"
field in the header that I expect to be 1590-54 = 1536
in the case of your uncompressed two line LUT. But with
my homebrew BMP-reader I get "image_size_bytes = 0" !?

Ernst

David,

Yes, the duplication factor is 'a/the problem?'

However EUMETCast is the most time effective way of obtaining this data for a reliable quick look - even on an 85 cm dish for the users I detailed.

John.

... and every duplication of HVS-1 data on the BS takes away capacity on the
BS. Likely if the lower-quality data would suffice, you could get it over
the Internet via e.g. FTP, as EUMETSAT already supply for their own
satellite(s).

Hi David
HVS charts were on the page, but you decided to delete them because I did not receive any data. now I'm receiving data from GORS 16.

David , I start receiving data from HVS1 from today. you can add my MRTG charts:

Added today, Robert. It seems that the entries were already there, but commented out, so adding involved much less work than I expected! Please check and let me know if any corrections are needed.

https://www.satsignal.eu/mrtg/performance_eumetcast-europe_losses.php#hvs

They should be there after ~06:35 UTC, not before.

Many thanks for providing the info!

the upper line is for land and the lower line for sea.
Find attached a RSS image from David's MSG Animator.

I just noted your LUT has TWO lines. IM treats this in a diagonal way.
Probably not good. Do you combine two channels or do you have
9 bit data? Could you post a typical image using your vis LUT?

Hi Ernst,

Got it! Did not expect to see the LUT that way displayed

Thanks.

Re: False colour LUT for VIS channels

Gerard,

The LUT is the fine line at the bottom of Thorsten's post.
It's a one line *.bmp image. Right click and save it to disk.

Cheers,
Ernst


Re: False colour LUT for VIS channels

GERARD BOON
 

Hi Thorsten, looking at Ernst's GOMS2 image looks nice and would like to try it but I can't see the LUT you are referring to. Is it in files?

Gerard


Re: False colour LUT for VIS channels

Ernst Lobsiger
 

Hi Thorsten,

I applied your LUT to a GOMS2 image received under GNU/Linux.
This image was processed using Pytroll (satpy) and IM. *NO* idea
whether this has any similarity with what you get with David's software.

Cheers
Ernst

Hi all,

I like to share the false colour LUT, I made vor VIS channels, especially for MSG HRV.
It brings out land structures and cloud structures as well.
It is for use with David's Software.
If you find it useful you are free to share it with others too.

Perhaps it helps, for use with TelliCast 2.14.4:

Once that's running tell us what's missing, and some more channels can be added!

Thanks thats very helpful.
