Camera position & nearby views
Virtual sky views of the same simulated weather.
Solar radiation
A dynamic estimate from the same cloud field shown in the sky and cameras. Colours follow cloud cover, building shadows and the angle of each surface.
Adjust sun manually
Modelled W/m², not measured Singapore irradiance. Includes direct-sun shadows from loaded buildings; distant shadows are coarser. Diffuse light and reflections are simplified. Model details
Scene & settings
Explore the changing tropical atmosphere over Singapore, from Marina Bay to the outer districts and islands.

Mapped buildings, streets and park paths sit over streamed Mapbox Satellite imagery and Copernicus terrain. Detailed photographs load around your view, with the local Sentinel-2 composite as a fallback. Imagery dates and source detail vary by location; photographs can contain their own acquisition-time shadows. The imagery is a basemap, not a live weather observation. Esri, Impact Observatory and Microsoft’s 2025 land-cover map guides forest, grass and urban materials. Its native resolution is 10 m; display textures use 20 m on desktop and 40 m on compact devices. NParks TreesSG supplies mapped tree positions, species and available height bands; crown shapes and fine surface textures are estimated. Other vegetation fills forest areas beyond the mapped inventory. Building heights and ground levels have mixed sources and accuracy.
Cumulus uses a Valladolid cloud simulation at 50 m horizontal and 20 m vertical source resolution, relocated and tiled over Singapore. The timeline interpolates 61 one-minute source frames through a full hour. Other cloudy presets are illustrative composites advected by the same clock. Satellite-guided mode uses the latest available observation or a selected recorded day from JAXA Himawari. Each real cloud mask, cloud top and optical thickness retrieval constrains varied LES and procedural clouds. Recorded dates remain fixed during synthetic playback. These coarse daytime observations are not a measured 3D reconstruction; cloud base, fine structure, wind and evolution are synthesized. Rain remains a separate illustrative preset. Camera images share the same field and observation snapshot; they are simulated views. Mapped outer districts load as you explore. Country terrain and satellite imagery include the main island and outlying islands; source resolution and completeness vary.
An interactive model with stylized details, not a surveyed photorealistic digital twin.
