About these statistics: Years is the equivalent number of classified years. Complete is the share of days classified from January 1, 2000 through September 30, 2026. Coverage lists years with at least half of the days classified; 2026 is included when at least 183 days are available. Green dots mark stations with 2026 classifications, amber marks stations updated in 2024–2025, and gray marks historical stations.
