Weather station CSV samples: units, missing readings, and metadata

Public and proprietary weather CSVs bundle station metadata with readings. Understand units, nulls, and elevation before analysis.

发布于 2025年3月19日 · Table

Weather agencies and research groups publish CSV slices for temperature, precipitation, and wind alongside station IDs and coordinates. Formats vary: some use explicit unit columns, others rely on documentation. Missing values may appear as empty cells, NaN strings, or sentinel numbers.

Before you model

  • Read the readme for unit conventions (Celsius versus Fahrenheit, mm versus inches).
  • Parse timestamp columns with explicit timezone or assume UTC only when the provider says so.
  • Join station metadata on stable IDs, not display names that change.
  • Flag long runs of identical readings that may indicate sensor freeze rather than calm weather.

Preview in Table

Table helps you preview thousands of rows, sort by station, and spot unit mix-ups in a side column before you commit the file to a heavier analytics stack.
