Hello,
From many days ago Eumetcastview doesn't remove side lines on VIIRS images when producing a pojection (same for MERSI). Before,it did it without issues.Which parameters should I set?
Thanks in advance.

It is working fine for me Daniele using the General Vertical Perspective or the new Oblique Mercator for NOAA 20 and NPP VIIRS and FY-3D MERSI.
Cannot reproduce your problem. Using Version 1.4.9.

Boxing Day A-68A Metop images.

geojohnt@...
 

All,

We seem to have be fairly lucky with cloud cover in the South Georgia area for several days now.
Well, at least we can 'see' through it in VIS.

Here are todays Metop-B and Metop-C images via EUMETCast and processed with David Taylor's HRPT Reader.

Regards,
John.

John,

 

1) Do you have your Jeeves at hand?

2) Do you have a lion-head rug on the floor?

3) Enjoy!

Hello All,

 

The turkey is in the oven with all the 'other bits.'

The roast potatoes are sizzling.

The sprouts and veg are cooking and the wine is chilling in the fridge. 

 

I'm afraid for me it's Christmas 'Dinner for One' this year.

Our German members will know 'what I mean' from Sylwester TV.

 

So, Happy Christmas and Seasons Greetings to All. 

And it's sad to see the demise of A-68A?

 

Best wishes,

John.

Re: A-68A turning again.

Ernst,

 

I had a chance to work with your suggestions and it works perfectly well. A first result is seen here: A68 (fvalk.com)

It seems that the next rupture will be lengthwise through the middle of A68 and that the pieces will soon bend around the southern tip of the elevated sea floor to continue north/northeast.

 

Cheers,

Ferdinand

Ferdinand,

it works like areas.yaml. This file takes precedence over the file areas.yaml in Satpy's 'etc' directory. In 'etc' there are subdirectories 'composites' and 'enhancements'.
There you find all current configurations built in. You can make the same subdirectories in your pppconfig and store your extra stuff there. I attach what I had to add
as a bare minimum to make 'hh' and 'hv' work for B&W images. This means you can also image single channels from an SDH file like the one from yesterday. Along
these lines it should be easy to make composites for 'vv' or 'vh' but also other dual combinations in SAR-C *.SAFE files. Have fun ...

But yes, it's inside Satpy for SSH. I make some latest tests for the absolute minimum you have to do (files you have to copy into your personal pppconfig) to make it work. Then I will publish my solution here. The latest Satpy documetation is still somewhat hard to read in this field. Stay tuned!

TBH I'am not a composite guru at all. Christian Peters is quite experienced in this field. But yes, it's inside Satpy for SSH. I make some latest tests for the absolute minimum you have to do

Ernst,

 

Excellent. Does that mean that you have found a solution to single versus dual polarization (SSH / SDH) issue in Pytroll/Satpy? Or do you mean with homebrew that you solved it outside of Satpy?

 

I couldn’t get single (hh) to work thus far.

John and Ferdinand,

while John noticed the first crack accross the A68a finger (on a Metop image!!) and Ferdinand added a final Sentinel-1A SAR-C measurement *.tiff confirmation,
I was unable to read the same GRDM file with Pytroll/Satpy because it only contained hh data. I have fixed that now by adding two homebrew sar-c composites.

Cheers,
Ernst


Re: A-68A 'finger' breaking away.

Thanks for the image update John.

 

Here is a link to the S1B image of yesterday and the S3A of today.

The Sar image can be opened in full resolution.

Hello Ernst and Luc,

Great images.

And todays cloudy Metop images show that the finger had broken right away and turned.

Happy Christmas to everyone and best wishes for a hopefully better 2021.
At least it seems one 'problem' is just about to be sorted out in the UK/EU?

John.

Hello John,

an even closer look below. This is 200 x 200km, 80m resolution (GRDM) with image width and height reduced 50%.
There should be a SAR file with 40m resolution (GRDH) on the Copernicus hub, but this will not fit in my PCs RAM.
