Could something be pulled from something like this?
or this?
https://www.aviationweather.gov/windtemp/data?level=low&fcst=06®ion=all&layout=on&date=
Seems to only cover N.A. though.. would need something world wide.
Where are these guys getting their data from?
If someone could locate a robust and free web API that would accept lat and lon as the arguments and provide the winds aloft data in real time, then yes, it can be done. So far, no one has located it. Paid providers collect that data in bulk from NOAA or similar sources, parse it and then expose it via their own custom web services on demand. This mod alone, without a similar backend, cannot do that.
I dont really know much about this, but this wouldnt work, hey?
REX is using this source for their winds aloft: NCEP Data Products GFS and GDAS
I suppose it’s not free, eh?
Canada uses NAV Canada data..
Im having some issues. The pics are from my balcony about 10km from the airport. While the screenshot is the live weather at the airport.. As you can see, there is definately a big difference but I dont understand how the weather can be THIS different..?
I understand aerosol denisty gives stuttering, but is it possible to show the density in the metar info, so that one can manually set to correct value when convenient . I.e start of flight or other?
But, its a great mod for sure!!!
Sorry, one more thought… where does LittleNavMap get its winds aloft?
Its open source and free software, so they must get it for free as well.. the provider seems to be NOAA.
@doc3d: If you examine the METAR, you will notice that there were no clouds layers in it, but there was a fog indicator (“FG”). It looks consistent with what you were seeing outside your window. By default, the mod does not set the aerosol density within the game, thus you didn’t see that fog reflected in your in-game weather.
@Andylbooth: The aerosol density, as well as all other information, is part of the METAR itself. You just need to know how to read it. As to your other question, if you have the aerosol density disabled in the mod settings (which is off by default), you can set it manually in your Weather Settings any time; the mod won’t touch it.
@FreedFlyer97231: As I mentioned above, finding some code or an example about the winds aloft does not help. The mod will need a backend server to utilize that information.
visibility is included in the metar as a number of statute miles (regular non-nautical miles) 10SM ususally means unlimited vis, 1SM would mean only 1 mile of visibility. Not sure how to correctly translate this to the aerosol density in the weather menu, but you could experiment
Just an idea. Why not asking for an one time fee of ~ $5-$10. I can imagine that many user will support the project because it’s a nice tool. ~300-400 user and you can buy and setup an backend server.

Let’s say it would go against the mod’s philosophy.
I like to donate for open source projects. The typical 2-3 coffees. I don’t find that indecent. I understand you position. That is very honorable.
I’ve added a FAQ page to the blog, so we can hopefully limit the endless Q&A string in this forum topic.
Unreal Weather - Live METAR FAQ
Have specific issues/ideas? Please PM or e-mail me directly. Thanks!
I noticed since the last version when the weather transitions and changes in the sim I get extreme lag and I have to click the button to load it instantly or it wont stop. What value can I change for this lag to stop ???
@patrickb1973, have you enabled the aerosol density in the mod settings by chance? If so, that could be the reason for the FPS drop, when any kind of obscuration is present in either one or both METAR reports.
Edit: Another possibility is that the weather transition step duration is too low. I’d be careful with anything lower than 0.1 sec.
No havent changed a thing everything is default, but I now changed weather_transition_span_seconds: and set it at 10 because 180 was the issue it asked too much of the sim to transition weather that long so experimenting with that
Did you try the per station METARs at Index of /data/observations/metar/stations ? Only includes ~6000 up-to-date METARs though 
FredFlyer97231 wants upper winds and METAR only provide surface reports. There is nothing in the tgftp.nws.noaa.gov site that provides upper winds.
Hi i have a doubt , its a great addon and many thanks to the creator , but it makes the quality of the clouds look worse or is it my idea?
Thx
@happygolucky32, there are only 3 variables available to the mod when it comes to clouds (except the altitude): cloud layer thickness, density and scattering. It cannot do anything beyond that.
To see what I mean, start with the Clear Sky preset, grab a single cloud layer and try to play with it. This way, it is much easier to understand what you can and cannot control.
