Hash commitment to the first partial 2026 national crop-yield prediction batch under a versioned ERA5-Land input policy: CP9B46
Year: 2026
Type: article
Abstract: This record documents a cryptographic commitment to the first partial 2026 national crop-yield prediction batch for maize, rice, soybeans and wheat. Only hashes and methodological disclosures are public; prediction values, agricultural targets and private paths are not released. The batch retains the complete system roster, named scenarios and unavailable entries. Predictions reuse models trained through 2024 under a fixed policy for consolidated ERA5-Land and authenticated preliminary ERA5-Land-T inputs. Local source-cutoff and seal times are distinguished from repository publication. These complete-season-weather estimates are not advance weather forecasts, and no universal blindness or future predictive skill is claimed. Subsequent batches and final-weather sensitivities must preserve the first-issued artifacts. Actual target evaluation requires separate authorization and committed source-matching and scoring rules. This record complements the original prediction commitment and the separately prepared T5 implementation commitment.
