Location and state climate summaries plus PlainClimate's station-to-Census-place identity crosswalk, served directly from the same database as the public pages. Choose CSV for spreadsheets or JSON for applications.
Available files
The three export families cover all 6,861 station-mapped location records and the 50-state ranking corpus. Row counts are computed from the live database and shown beside each file.

Identity crosswalk
What each location label represents
PlainClimate location labels originate with primary NOAA climate stations, so they are not all municipalities. The crosswalk tests every label against the official 2024 Census Gazetteer Places file using a conservative exact normalized name-and-state match. Only unique matches receive a Census GEOID; collisions and no-matches remain explicit.
- Incorporated place
- 3,347
- Census-designated place
- 570
- Other Census statistical place
- 2
- Ambiguous exact match
- 18
- Unresolved / no exact match
- 2,924
Unresolved is an upper bound on facility labels: conservative name matching can miss spelling variants. The files preserve the primary station, station coordinates, class, GEOID/LSAD when defensible, confidence, method, source URL, and vintage for every row.
Provenance and reuse
The underlying observations are NOAA public-domain data, and the identity file uses the U.S. Census Bureau Gazetteer. PlainClimate releases these derived tabular presentations and exact-match crosswalk under CC0 1.0. Each JSON file includes its source URL, data vintage, license, row count, and suggested citation; CSV files carry the same facts in comment rows.
These are long-run climate normals, not current conditions, forecasts, or future projections. See the methodology and the national statistics report before using the figures in consequential decisions.
Every figure on PlainClimate is rendered directly from NOAA 1991-2020 U.S. Climate Normals data, no number is typed in by an editor. The files are generated from the same database rows that power PlainClimate's location and state pages; place identity uses a conservative exact name-and-state crosswalk.
