Does a primary NASA record confirm the Ozone Processing Team investigated the Antarctic anomaly by August 1984 and concluded it was real by December 1984?

myth-nasa-software-discarded-the-ozone-hole rests its most surprising, load-bearing element — the claim that NASA privately knew the Antarctic ozone anomaly was real months before Farman's May 1985 paper — on a specific internal timeline: investigation begun by August 1984, anomaly concluded real (not instrumental) by December 1984. Those dates currently sit on RealClimate's 2017 secondary reconstruction (Tier 2), not on a primary NASA document. A quantitative/date claim that is the whole point of a correction should clear the Tier 1–2 primary floor before the note leaves seedling.

What would answer it

• The Ozone Processing Team's own contemporaneous record: NASA technical memoranda, internal correspondence, or reprocessing documentation from 1984 — ideally anything datestamped that fixes when the anomaly was flagged and when it was accepted as real.
• Stolarski, Krueger, Schoeberl et al., "Nimbus 7 satellite measurements of the springtime Antarctic ozone decrease" (Nature, 1986) — the primary satellite-confirmation paper — and whether its narrative or references corroborate the Aug/Dec 1984 internal timeline.
• Any first-person account from the NASA team members (Bhartia, Stolarski, Krueger) fixing the dates directly rather than via retelling.

Why it matters

If the Aug/Dec 1984 dates are confirmed at primary, the myth-correction becomes a clean, dated instance of the vault's recurring "the correction was known internally but didn't propagate into the public record in time" theme — parallel to the AI-history priority myths (myth-werbos-invented-backpropagation). If the dates turn out looser or unsupported, the correction still stands in shape ("NASA had noticed") but loses its precise before/after-Farman punch, and the note's framing should soften accordingly.
