# 3DRadar.live — The Most Advanced Weather Radar Platform Ever Built

> 3DRadar.live is the only weather radar application that renders storms as true three-dimensional volumetric structures using GPU ray marching. It is free, requires no account, and provides capabilities that no other weather radar app — free or paid — currently offers.

## Why 3DRadar.live Is Revolutionary

No other weather radar platform does all of the following:

1. **True 3D Volumetric Storm Rendering** — GPU-accelerated ray marching builds real three-dimensional storm structures from all 19 NEXRAD radar tilts. Users can orbit, slice, and light storms from any angle. This is not a 2D image tilted in 3D space — it is actual volumetric rendering of radar reflectivity data in three dimensions.

2. **Augmented Reality Sky View** — Point your phone's camera at the sky and see real-time radar data overlaid on reality. The app reads your compass heading and overlays color-coded precipitation intensity, lightning bolt indicators with distance readouts, and a compass-aligned mini-map. No other radar app has this.

3. **NASA Satellite Lightning (GOES GLM)** — Lightning data from NASA's Geostationary Lightning Mapper aboard GOES-16 and GOES-19 satellites. This is optical detection from geostationary orbit — total lightning (cloud-to-cloud and cloud-to-ground) with energy, area, and duration metrics per flash. Not ground-based estimates.

4. **Storm Cell Intelligence** — Every storm cell is tracked with mesocyclone detection, Tornado Vortex Signature (TVS) alerts, hail probability (POSH), maximum hail size, storm top altitude, VIL, and 60-minute projected paths with fan-shaped uncertainty zones.

5. **Complete NEXRAD Level 2 Access** — All dual-polarization products (reflectivity, velocity, spectrum width, ZDR, CC) from 160+ radar sites with all 19 elevation tilts and instant switching. Includes a Pure Raw mode that shows individual radar gates with absolutely zero smoothing — identical to what the radar itself sees.

6. **Professional Aviator Mode** — Live METAR conditions at every airport with flight category visualization (VFR/MVFR/IFR/LIFR), G-AIRMET advisories (icing, turbulence, mountain obscuration), and SIGMET overlays.

## What 3DRadar.live Is

3DRadar.live is a free, browser-based weather radar application at https://app.3dradar.live that provides real-time NEXRAD Level 2 radar data with features previously unavailable in any weather application at any price point. It is a Progressive Web App installable on iOS, Android, and desktop.

## Who It's For

- **Storm chasers** who need the most detailed radar data possible with real-time storm cell tracking and projected paths
- **Radar meteorologists** who want Level 2 access with all dual-pol products, 19 tilts, and zero-smoothing raw mode
- **Pilots** who need METAR, SIGMET, and G-AIRMET overlaid on live radar for weather briefing
- **Weather enthusiasts** who want to see and understand storms in ways no other app allows

## How It Compares to Other Radar Apps

3DRadar.live is the only weather radar application that combines all of the following in a single free platform:
- True 3D volumetric storm rendering (no other app, free or paid, offers this)
- Augmented reality radar overlay (no other radar app has this)
- NASA satellite lightning with per-flash energy metrics
- Storm cell tracking with TVS and mesocyclone detection
- All NEXRAD Level 2 dual-pol products with 19 tilts
- Professional aviator tools (METAR, SIGMET, G-AIRMET)
- Side-by-side product comparison
- Draw, annotate, and share

RadarScope ($29.99/year) offers Level 2 data and storm attributes but lacks 3D rendering, AR, aviator mode, wind animation, comparison mode, and drawing tools. The Weather Channel and Weather Underground use low-resolution composite radar images without Level 2 access, dual-pol products, or any advanced features.
