# Create a wind particle animation
This example adds a data-driven particle animation onto a map.
A wind tileset derived from the Global Forecast System (GFS) is visualized as a particle animation. First, a [`raster-array` source](https://docs.mapbox.com/style-spec/reference/sources/#raster-array) is added containing the wind tileset in the [Mapbox Raster Tile](https://docs.mapbox.com/mapbox-tiling-service/guides/raster-mts/) format. Then, a [`raster-particle` layer](https://docs.mapbox.com/style-spec/reference/layers/#raster-particle) is added to render the animation.
> **Note (warning): Accessing Sources with Raster Layers**
>
> This example uses a pre-built `raster-array` source. To create your own raster array source for particle visualization, you'll need to upload and process your data using Mapbox Tiling Service — see the [Visualize Wind Data](https://docs.mapbox.com/mapbox-tiling-service/examples/raster-mts-wind/) example for steps.
