Thank you Ernst & David for your comments concerning my dilemma. The easy way out seems to be Windows 10, making sure that I check the necessary options re security.

Hi Hugo,
Thanks for that, much appreciated.
I have a lot of difficulty reading Danny's presentations, so wouldn't surprise me if there's an error in there somewhere! The Pytroll code looks correct to me so that's probably the best example to follow.
If it's a lot of work to update the menu then I wouldn't worry about that, if you can do a debug hack to save BTs + Refl for one recent timeslot then just send those to me and I'll have a look, probably simpler than altering the whole code.

Cheers,
Simon

Thanks for the tip. 
If I do not find the reason for the difference  I will include a menu entry that can create a file with, for example100 x 100 brightness temps or reflectances. I will keep you informed.

Hi Hugo,
I'm glad that you're using our seviri_util code, which was also made by Greg McGarragh, not just me :-)
But can I ask that you include the copyright notice and a link to the github repo where you use our code? I see a few files in EUMETCastview that have been taken directly from seviri_util but do not respect the GNU GPL licence. To my (limited) knowledge the files from seviri_util must remain under GPL. Sorry to be a pain in the ass, but Greg and I were employed to develop that code and as it's good to ensure it's distributed in accordance with what our employer asked for. Thanks!

Regarding the RGB colour issues, I had a look at your code but there's a lot of files and it's not immediately clear where the brightness temperature and reflectance calculations are done. I see that you're using a similar method for the 3.9 channel as PyTroll does, but there are some differences. I'd suggest using exactly the same formulae as PyTroll and seeing if that helps. Their code starts is near line 80 of this: https://github.com/pytroll/mpop/blob/master/mpop/instruments/seviri.py

You could also try the method we use in our retrieval software (ORAC), which explicitly calculates the solar term. You can see it in this file, starting on line 337: https://github.com/ORAC-CC/orac/blob/master/src/FM.F90
This might be overkill for your purposes but it works nicely for us! The F0 value for SEVIRI PFM is 4.6265.

Is it possible to save images showing the raw brightness temp and reflectance values calculated by EUMETCastView? If so, I'll compile the code and compare a couple of outputs to ORAC to see if that helps narrow down the differences.

Cheers,
Simon

Re: EUMETCastView v1.3.9

Christian and Hugo,

O.K. the the EUMETSAT version is superior then. I just looked at the thumbnails on the MSG1-list: Earlier the (reddish) EMCV Image was at left and now the (rather pale) EMCV Image is at right. Unless I open the images in IE I get just names 0,png and 1.png. So I was kind of confused. Hugo will certainly fix it :-).

Cheers,
Ernst

===============================================================

Manu this is not image data but sounding data. The NOAA 20 VIIRS image data is still on test on Transponder 2 and has not yet been released. It is identical to the NPP VIIRS data. When available the current version of EUMETCastView can manage the NOAA 20 VIIRS M and DNB files. I expect the data to become available quite soon as it has been on test for some time.

In the 'Severe Storms' RGB recipe parameters was a small bug. This is  fixed ,and the 'red' globe is now 'purple'.
However for the Snow and Day Microphysics ( which uses the IR_039 sun reflection ) I am still searching for the reason.
There are many ways to calculate the IR_039 sun reflection. My calculations include the CO2 correction from the IR_139 band, maybe this is the reason.
I will experiment a bit more later today.

Ernst,

the version with more orange-blue is the version provided by Eumetsat (even similar colors with xrit2pic and Pytroll). The version with red and cyan is the EMCV version.

(see filenames)

Re: Linux or Windows 10?

Peter,

With Ubuntu desktop out of the box Canonical will most probably
also collect personal data. I use Debian 9 (Stretch 64 bit) but
also Devuan 2.0 (ASCII 64 bit) because I do not like systemd on
Eumetcast receivers. My machines are pure CLI systems. On a 10
year old PC with a TBS-6903 I can receive both T1 + T2 with a
single cable to the LNB, process all Sentinel 3A EFR images and
export the rest of the data via NFS. With Linux you can still
taylor systems that do what you want and that update only things
you ask them to. The downside is a rather steep learning curve
and only a few people (but including K.P. Renner and G. Potiriadis
at EUMETSAT!) that can help you if you are really stuck. And of
course there is nothing like David's site for Linux users. Image
processing can be done under Linux with Rob's Xrit2pic, Hugo's
EUMETCastView, Gimp, SNAP, IM, and Pytroll (that moves to SatPy).

Cheers,
Ernst

I am busy assembling a machine in order to receive and process Eumetcast data from HVS-2. I will be using another TBS 6903 but what concerns me is the operating system. I am using Windows 7 64bit for the machines running BAS and HVS-1 and I was going to use Windows 10 for the new pc. However I believe that this OS collects virtually everything it can, see https://privacy.microsoft.com/en-us/privacystatement

I know that there are a few out there using Linux. I use Ubuntu on other pcs but is it feasible for my requirements?
====================================

Peter,

Yes, Windows-10 can collect data if you choose to enable those options, but you can turn most of it off, especially in the current 1803 release. I have no issues with Windows-10 on that account, and I know than many here use Windows-10 without issues.

Google "disable personal data collection windows-10" for help.

David
