TorNet v1.1 last-frame radar chips, training days
The training-day samples of TorNet v1.1 (171,666 chips, 2013 to 2022), each reduced to its last frame: six WSR-88D
Level-II variables (DBZ, VEL, KDP, RHOHV, ZDR, WIDTH) on the 0.5 and 0.9 degree sweeps and the range-folded mask,
on the native polar grid (120 radials at 0.5 degree, 240 gates at 250 m), one NetCDF4 file per chip, in tar shards
chips-<year>-<k>.tar holding chips/<year>/<chip_id>.nc. SHA256SUMS lists the shards' checksums.
The files carry no labels, EF ratings or Storm Events identifiers, and chips are renamed to arbitrary ids.
