# MCS morphology — labeling frames

Two-panel radar plots (SL3D classification mask beside composite reflectivity) for
tracked mesoscale convective systems over the contiguous United States, packaged to be
served to the labeling platform at
<https://huggingface.co/spaces/skyan1002/mcs-morphology-labeler>.

Layout: `{year}/track_{id}/{frame:03d}.png`, where the frame number matches the index in
the original `mcstrack_YYYYMMDD_HHMMSS_N.png` file name and the time index of the
corresponding track NetCDF.

These are the frames that carry **no morphology label yet**. 2004 is fully labeled and
270 of the 370 tracks in 2005 are labeled; neither is included here.

Per-frame metadata — valid time, system motion direction and speed, precipitation-feature
shape — lives in the manifests inside the Space, not in this repo.
