@grojzdila Hello, you probably talk about animated particles in layers. Do you have them turned on in the menu of our app?

@Filip_K ! Solved. Somehow animation was turned off. Thanks for help. [image: 1709238023917-screenshot_20240229_221936_windy-resized.jpg] [image: 1709239112013-screenshot_20240229_223736_windy-resized.jpg]

@spetithuguenin The one hour difference between the Meteogram and the wind arrows is known and must be fixed. Concerning the difference with the Squid app, which weather model do you use? Squid offers GFS data as a free version, and the ECMWF only as a paid version.
