let view = new SceneView({ container: "viewDiv",
map: new Map({ basemap: "satellite", ground: "world-elevation" }), environment: { weather: { type: "cloudy", cloudCover: 0.8 // autocasts as new CloudyWeather({ cloudCover: 0.8 }) } }});The weather visualization updates as soon as the property changes:
view.environment.weather = { type: "cloudy", cloudCover: 0.4 // autocasts as new CloudyWeather({ cloudCover: 0.4 })}Constructors
