@idefix37 well there's still an issue that model shows 4 m/s at 10m above ground while reality will be 17 m/s and more

But I understand model limitations. Hope we can agree on that.

Thanks.

Hi, since few days ago mobile app is not working, it shows basic map and hangs, Android reports unresponsive app .

Anything else I can provide?
Reinstallation didn't help.

I see some issue with meteogram wind strength.
Look at the sample, at 2700 AMSL wind is 17m/s.
But meteogram for the spot shows 4m/s, which is for 1000hPa theoretical height (underground).

I clicked on the spot on map to get prediction for it's location and altitude.

So, in my opinion, basic meteogram, doesn't reflect altitude, so it provides highly inaccurate predictions. Especially for paragliding pilots it is super important to consider wind strength at takeoff altitude.

It is pretty tricky and the only way how to get strength for altitude is use Airgram or Wind layer at height.

I believe this shall be fixed as it leaves quite a lot of space for misleading user.

@Suty My Google Pixel 8 is not running any beta version, just to be clear.
Anyway, fingers crossed for resolution...

Hi @idefix37,

thanks for explanation, now I understand the issue with wind at ground level at 10m height. Truly you're right, most models do use the some extrapolation,
ECMWF for reference https://confluence.ecmwf.int/display/FUG/9.3+Surface+Wind

However, even ECMWF admits there're issues with 10m ground levels (see the article). Especially we will experience high inaccuracy for higher altitudes, stronger winds or complex orographies.

As base meteogram is a tool of daily use (as a pilot I check before I go hills to fly, for tourism in mountains the same, before I go ridge hike I check wind), would it make sense to extend meteogram and show wind at altitude?

People can really misjudge situation based only on 10m extrapolated ground wind.

Thanks for answer!

@ondrejspilka723 EDIT - just precised title...

@idefix37 and why I setup slider? To see real wind in 2700 AMSL.

What do you mean by ground surface? AMSL or altitude of location?

@idefix37 yes I added the same comment when I realized it is worth of report. Sorry for any confusion.

Why is meteogram showing wind at 1000hPa? It just doesn't make sense since main location entry point is map with surface. Location shows altitude. User wants to see wind at location thus at altitude.

I could understand wind respects height slider, but that's not the case either.

@Ondřej-Šutera Thanks, appreciate.
