What is included?

Daily difference statistics, coverage and quality counts for all 70 retained station histories, plus nationwide and map summaries. 68 stations qualify for completed-year peer rankings. Duplicate Salt Lake City #80 is excluded.

No original forecast data is distributed. This edition omits forecast temperatures, hourly pairs, prediction/reference IDs, forecast bundles and reading-level audit records, including raw examples embedded in the originating outlier report. The day inspector uses aggregate means and counts.

The published statistics preserve the full source summaries; dates are not randomly sampled or invented. Mean differences compare forecasts with stored near-term forecasts, not observations.
