Latest add-on: both South Georgia and A68 in a single image (Sentinel 3A today). Separated by only 1,5x the width of the island.

Ernst,

 

Looking again more attentively I think you are right, as also the coloration (blueish vs. white) neatly follows the contour of the cloud.

Well spotted!

 

Cheers,

Ferdinand

Ferdinand,

that's a very nice image. I wonder if the structures we see on the ice is not copied from the thin cloud overhead (see gray cloud lower left of A-68a).
Unfortunately Sentinel 3A/3B have repeat cicles of 27 days, so the last picture of this quality should be from November 5th. And *YES*, here it is!

Cheers,
Ernst


Re: Eumetcast - SatPy Problem: "No IMPF configuration field found in prologue" [SOLVED]

Francis Greaves
 

Ernst, THANK YOU once again for a useful clue!
I have looked again at the problem.
I have discovered that it is nothing to do with the No IMPF configuration field found in prologue warning. it is a problem with loading the BlackMarble file.
Setting up a simple script I discovered this error being output:
Don't know how to open the following files: {'/home/francis/FG-Docs/Downloads/BlackMarble_Images/BlackMarble_2016_01deg_geo.tif'}
So enabling the satpy debug and looking again at the output I found the answer:
SatPy could not open the BlackMarble tiff file because the rasterio module was not installed. Once I installed that, the image was created.
Problem Solved!


Re: Signal quality

Giftmacher
 

I have the LNB you mentioned. So you think the signal quality I have correspond with the dish size?

Yes.  Did you not follow the user invite to test which was on Twitter?

Sadly, it's broken many of the links, including links found by Google. 
It makes it more difficult to help folks when you know the information 
is there, but it can't be found.

Re: Signal quality

Ernst Lobsiger
 

Giftmacher

A 85cm dish is about the bare minimum for acceptable Basic Service and maybe some HVS-1.
I recommend a 110cm -125cm dish and the Inverto Black Ultra HGLN LNB that many of us use.

Ernst


Signal quality

Giftmacher
 

Hi again, I was tinkering with antenna yesterday and SNR increased from 10.8 to max.11.8-12, but I
think the quality of 58% is still low, should it be better on a 85cm dish? Could that cause the problem I'm experiencing?


Checking a LNB

diogenes1@...
 

Hello All,
Thank you to those who replied to my settings request. Other than mounting an LNB into a dish and checking for a signal is there any other way, perhaps using a multimeter, to check whether an LNB is functioning?
Regards, Peter

May I add yesterday’s Sentinel 3B 11:29 image, showing considerable ice surface detail.

Re: Eumetcast - SatPy Problem: "No IMPF configuration field found in prologue"

Francis,

have you tried the full monty debug stuff? Before the script code begins:

from satpy.utils import debug_on
debug_on()

BTW: I got this too, but it’s just an info:

[INFO: 2020-12-02 20:36:07 : hrit_msg] No IMPF configuration field found in prologue.

Didi you try other slots!? Maybe this one slot is corrupt due bad receiving?

Francis,

al fine here with this composite, see pic. Do you really provide all channels uncompressed and even the PRO and EPI file? Could you check whether „files" contains all needed files? Maybe you should post some more of the code?

Hi folks, hope you are all well, greetings from South West Ireland!
I have been using Pytroll, then SatPy for some time in Linux. I moved to Python3 a few months ago, got is sort of sorted, but for a while I have problems with the natural_color_with_night_ir and night_ir_with_background Composits.
I use the first for creating an animation. It used to work, but not now.
I am even providing all the available wavelengths in case I have one missing, but I still get the same error.
When I run the script and get to the global_scene.load([self.composite]) I get this error hrit_msg - INFO - read_prologue - 287 - No IMPF configuration field found in prologue.
I have looked at the SatPy Issues, nothing there. There is apost here  but that was caused by misnaming the composit. The composit I want is definitely in the reader global_scene = Scene(filenames=files, reader='seviri_l1b_hrit')
Does anyone have any ideas why I get this?
 Thanks.......
