// The Hodograph, Unfolded
Atmospheric Visualization · FullCourt Press LLC
HodoDecoder 3D restores the dimensions that standard atmospheric diagrams suppress — altitude becomes a spatial axis on the hodograph, and time becomes a spatial axis on the Skew-T. Fly through the wind profile that produced El Reno. Watch a sounding evolve hour by hour as a volume you can orbit.

// About the Project
Every severe-weather forecaster reads hodographs and Skew-Ts. Both are brilliant compressions — and both pay for that compression by discarding a dimension. The hodograph flattens altitude into a line you must mentally re-inflate. The Skew-T freezes a single moment and hides how the atmosphere is trending.
HodoDecoder 3D puts those dimensions back. The wind profile becomes a structure you orbit, climb, and interrogate level by level. The sounding becomes a volume that carries its own history, so destabilization is something you can see rather than infer.
Built by a sole developer, validated against the storms that matter — the El Reno 2013 EF5 profile ships as the built-in reference case — and engineered around one uncompromising rule: the display never claims more than the data supports.
// The Suite
The wind profile as a true spatial object — altitude on its own axis, with rotational character encoded directly into the trace. Orbit the structure, inspect any level, and read storm-relative geometry the way the storm experiences it.
Core · WebGLA time-evolving sounding volume. Successive profiles stack into a solid you can fly along, making destabilization, moistening, and capping trends visible at a glance — with observed cross-sections visually distinguished from interpolated ones, always.
Time EvolutionA full classical hodograph workbench with severe-weather parameters, storm-motion vectors, and a research-derived tornado-probability nomogram — plus one-click handoff of any profile into the 3D suite.
Analysis + HandoffPull observed radiosonde launches from the global archive or generate model pseudo-soundings from HRRR and RAP for any point and hour — server-side thermodynamics computed with the same tools researchers use.
RAOB · HRRR · RAP// Data Integrity
Missing data renders as a visible gap. Nothing is smoothed over, nothing spans a hole in the record. If a level wasn't measured, you see that it wasn't measured.
Observed balloon data and model output are labeled distinctly at every surface of the app. A model pseudo-sounding never wears an observation's badge.
Rendering scales are anchored to physical units, not stretched per profile. El Reno and Pilger can be compared honestly, side by side, because neither is normalized to look maxed out.
In the time volume, real cross-sections carry a luminous treatment; in-between frames stay matte. You always know which slice the atmosphere actually reported.
