Resolved Incorrect weather at LGIR

[Kubilay]

Hi! I love ASFS, its really a big upgrade on visuals, although there seems an increasing trend in weather mismatch. I want to adress this because I regulary get a live weather mismatch, I always verify with windy. com and the live webcam. Live weather in ASFS updates seem to regulary significantly change aswel. I will give you this instance:

Location: LGIR
Date: 3 june 2024
Time: around 18:20 zulu
Comparison: MSFS live weather/ ASFS / windy .com live webcam at the time.

LGIR 031750Z 00000KT CAVOK 25/18 Q1014 NOSIG

also my settings are the realistic preset.

The in-sim clear skies is the correct one and is MSFS live weather, the somewhat overcast picture is from ASFS

I hope I can adress this here properly, because due to this, I am reverting back to MSFS live weather unfortunately...

Kind regards,

Kubilay Kaplanoglu

Without more information, it's impossible to diagnose.

Was this while setting up for a flight after you had loaded in, or was it after landing there? Is there a flight plan set up in ASFS?

The METAR shown in ASFS is significantly different than the one you copied in (where does that one come from?). Is the Conditions page in ASFS showing the same METAR if you input the ICAO code rather than using the current location window?

If you just landed there are a slew of other questions.

I went ahead and pulled up the same conditions but made the time of day in MSFS a little earlier so that you could actually see the clouds instead of dark skies.

Here is a screenshot of the conditions page and the related ASFS windows (showing the same METAR - @damian I have mentioned this before, but the time I need to input in the Weather Date and Time window is an hour earlier than it should be for the METAR that is being retrieved):


Here is a picture with my usual settings (overcast/cloudy, right?):


Based on user feedback about clear skies when the METAR showed CAVOK, Damian and the team changed the options to add more clouds when it's CAVOK conditions (under Cloud options, it's the one called Add clouds for CAVOK/NSC/NCD/Unspecified). Here is a picture with that setting turned off:


I think that looks more like what you are hoping for, so you may want to check that setting and turn it off if you don't want clouds in those situations.

It was when I landed there, there is no flightplan setup in ASFS. The METAR was the actual metar of LGIR when I took the pictures.

Okay, yeah I just want reallife weather without adjusting the settings everytime for a flight, there will be scenarios where its the other way around, where clouds are there but metar reports CAVOK. Then I have to change it all the time.

 

[damian]

Right now the CAVOK generation does not fully blend GRIB and METAR data when lots of METAR data is present, and is more predictive based on temp/dew trends vs grib cloud cover data, and doesn't always get this right... this will improve later on. For now it is recommended to leave that option off if you don't want ASFS to identify and depict additional cloud layers (which it did in this case).

 

[damian]

FWIW, we have adjusted the predictive logic to provide less cloud overall in the interim while we integrate further GRIB data hybrid cloud data with METAR data. Look for this in next build coming soon.

Thanks for getting this to attention and processing it. I hope I can fly without any incorrect weather in the future, for now using MSFS live weather...

 

[Kubilay]

After arriving in LEGE without latest build, the weather was incorrect, once i downloaded the latest build quickly, the weather was correct all of a sudden! Happy me . So im reporting this is fixed for now, thanks! If I find any incorrect weather in the future I will report it here.

Nevermind, inaccurate weather changes still occure. for example, IRL over NL there is scattered clouds, firstly it updated to clear skies, then I press update and then it was fully overcast, and then i pressed again update and it was finally scattered as it should be, IDK what is going on here but I am annoyed I have to update everytime and hope it will be something like real life.

How are you updating the weather?
What was the METAR showing for your location?
Were you in the air or on the ground?
Were you at an airport?
Was there any interpolation shown in the conditions page?

 

[Kubilay]

FYI, I stopped using ASFS due to the unreliable accuracy of weather, where in my experience MSFS live weather has better accuracy, it may have weird clouds, but at least the weather conditions/transitions are far more accurate than ASFS. My last moment for now was at EBBR, A few moments ago, where it was heavily raining, and all of a sudden, BOOM blue skies just a few clouds but thats it, no more rain. I checked with IRL conditions, and it was stopping with raining and clouds getting more clearer. But instant change in weather? comeon....

Try removing your other weather add-on that is causing this. https://forums.hifisimtech.com/threads/no-weather-shown-in-simulator-or-instant-weather-changes.14820/

comeon....

 

[Kubilay]

I dont have any other weather add-on's other than ASFS.

 

[damian]

ASFS cannot command an instant weather switch unless you've asked it to by changing options, loading a flight plan, hitting refresh button, etc.

You've never had any other weather add-on installed, and you are getting instant weather reloads without commanding them? That would be a first, would be great for you to open a ticket so we can investigate along with the other cases (so far 100% have been due to other weather add-ons despite users claiming over and over they did not have them installed). But we'll still investigate.

 

[Kubilay]

My apologies, maybe I have written it wrong. With weather transitions, I mean the following: When opening active sky on an airfield where there are a few clouds or scattered clouds IRL, it opens with clear skies, then I refresh the weather, it shows fully overcast, then I refresh again, and only then it shows few or scattered clouds. Now this is just an example of what I mean. The variation of weather changes when frequently updating the weather via Active Sky FS.

I will also investigate if any other addons are interfering with ASFS in the mean time.
