What GR2Analyst does, but smarter

Every tool a weather enthusiast needs, enhanced with machine intelligence.

REFLECTIVITY

Full Level 2 Products

Base reflectivity, velocity, spectrum width, and all dual-pol products (ZDR, CC, KDP). Super-resolution rendering at 0.25km gates.

AI:DETECT

AI Storm Cell Tracking

Machine learning identifies mesocyclones, hook echoes, and debris signatures automatically. Plain-language alerts when rotation is detected.

VELOCITY

Rotation Analysis

Automated velocity couplet detection with gate-to-gate shear calculations. AI highlights rotational signatures you might miss.

RENDER

WebGL Radar Engine

GPU-accelerated rendering handles millions of radar gates without dropping frames. Smooth pan, zoom, and animation at 60fps.

FORECAST

AI Nowcasting

Predict storm motion and intensity 0-4 hours ahead. See where cells will be, not just where they are.

ARCHIVE

Historical Replay

Access the complete NEXRAD archive on AWS. Replay any storm from 1991 to present with full Level 2 fidelity.

The same data meteorologists use. Free.

NEXRAD Level 2 is the highest-resolution radar data available from the NWS network. It's been free on AWS since 2015. But until now, viewing it required expensive desktop software designed in the early 2000s.

StormLens streams it directly to your browser. Every volume scan. Every tilt. Every product.

  • Base Reflectivity (all tilts)
  • Base Velocity (storm-relative available)
  • Differential Reflectivity (ZDR)
  • Correlation Coefficient (CC)
  • Specific Differential Phase (KDP)
  • Spectrum Width

Weather radar belongs in the browser. AI makes it useful for everyone.

Storm chasers shouldn't need a $250 license and Windows to see what's happening in the atmosphere. StormLens puts NEXRAD Level 2 data where it should have been years ago, with intelligence that makes professional-grade radar accessible to anyone who cares about the sky above them.
