⚡ Physically-Modeled Ionospheric Aurora

Atmospheric Northern Lights for Modern Web Design

Modeled from 100,000+ energetic solar wind electrons cascading along Earth's dipolar magnetic field lines. Featuring altitude-dependent quantum emission spectra from 80 km to 380 km altitude, running at locked 60 FPS on pure WebGL2.

Geomagnetic Dipole Alignment

Auroral rays are true 3D field-aligned Birkeland currents plunging into Earth's polar atmosphere at 75°–85° inclination. Looking at the magnetic zenith produces the authentic 360° corona.

🌌

Altitude Spectral Chemistry

Realistic quantum emissions: N₂ molecular crimson fringes at 80 km base, vibrant atomic oxygen 557.7 nm emerald core at 120 km, and diffuse O(¹D) 630 nm ruby red crown reaching 380 km.
