The Weather component allows easy selection and configuration of weather effects in a Scene component. The available weather types are: sunny, cloudy, rainy, snowy, and foggy.

To set the weather programmatically, apply the desired weather type to the environment property of the Scene component.

// Access the Scene component.
const viewElement = document.querySelector("arcgis-scene");
await viewElement.viewOnReady();
// Specify the weather settings.
viewElement.environment.weather = {
   type: "rainy", // autocasts as new RainyWeather({ cloudCover: 0.7, precipitation: 0.3 })
   cloudCover: 0.7,
   precipitation: 0.3
};

To determine if the weather visualization is available, check the boolean value of viewElement.environment.weatherAvailable. The weather is only available:

  • in global viewing mode,
  • when atmosphereEnabled property on environment is true,
  • at lower altitudes, near the ground.

Known limitations

Weather is only supported in a 3D Scene component.

autoDestroyDisabled

Property
autoDestroyDisabled: boolean

If true, the component will not be destroyed automatically when it is disconnected from the document. This is useful when you want to move the component to a different place on the page, or temporarily hide it. If this is set, make sure to call the destroy method when you are done to prevent memory leaks.

Attribute
auto-destroy-disabled
Default value
false

headingLevel

Property
headingLevel: 1 | 2 | 3 | 4 | 5 | 6

Indicates the heading level to use for the title of the component. By default, this message is rendered as a level 4 heading (e.g. <h4>Time range</h4>). Depending on the component's placement in your app, you may need to adjust this heading for proper semantics. This is important for meeting accessibility standards.

hideHeader

Property
hideHeader: boolean

Whether to hide the component's header.

Attribute

Default value
false

icon

Property
icon: string

Icon which represents the component. Typically used when the component is controlled by another component (e.g. by the Expand component).

The component's default label.

Attribute

Attribute

referenceElement

Property

By assigning the id attribute of the Map or Scene component to this property, you can position a child component anywhere in the DOM while still maintaining a connection to the Map or Scene.

Attribute
reference-element

state

readonlyreflected
Property
state: "disabled" | "error" | "ready"

The current state of the component.

Attribute
state

view

Property
view: SceneView

The view associated with the component.

Note: The recommended approach is to fully migrate applications to use map and scene components and avoid using MapView and SceneView directly. However, if you are migrating a large application from widgets to components, you might prefer a more gradual transition. To support this use case, the SDK includes this view property which connects a component to a MapView or SceneView. Ultimately, once migration is complete, the Weather component will be associated with a map or scene component rather than using the view property.
