Wind direction
By logger-program period (vs airports, after applied corrections)
Measured offset W = °. Predicted 30-ft rotation with no correction code = 180 − W; with the sign-flipped line = 360 − 2W.

How to read this
Levels: 0 good, 1 suspect, 2 failure, 9 missing. Each variable's level is in QC_<variable> in the data file; the events file lists every flagged run with the test that set it. Station-level findings summarize patterns (sensor rotation, clock offsets, duplicate soil depths) that per-record flags can't describe on their own. Wind direction flags use daily vector means, so a flagged day marks every record in that day.
