NOAA ISD Global Hourly Parquet

This dataset contains the full NOAA Integrated Surface Database / Global Hourly weather observations from 1901 to 2005, converted to Parquet and partitioned by year.

The source data is derived from NOAA/NCEI Integrated Surface Database observations distributed through the public NOAA Global Hourly archive.

Data layout

Each row is an observation report, not necessarily one row per station-hour. Some stations report more frequently than hourly, and some report sparsely.

Common columns include:

• —station_id
• —timestamp
• —source
• —latitude, longitude, elevation
• —name, reporttype, qualitycontrol
• —temperaturec, dewpoint_c
• —winddirdeg, windspeedms, windgustms
• —ceilingm, visibilitym
• —sealevelpressurehpa, altimeterhpa, stationpressurehpa
• —associated NOAA quality-code fields

Quality-code columns are stored as one-character strings and preserve source codes, including numeric and alphabetic codes.

Notes

• —Timestamps are UTC.
• —Coordinates and station metadata are repeated on each observation row for convenient filtering.
• —Missing source sentinel values are represented as nulls where applicable.
• —This is an observation-level dataset; it has not been resampled to a regular hourly grid.

License and attribution

This dataset is a derived Parquet conversion of NOAA/NCEI Integrated Surface Database / Global Hourly public data.

NOAA data distributed through the NOAA Open Data Dissemination Program are open to the public and can be used as desired. NOAA requests attribution when NOAA data are used or disseminated. Do not state or imply NOAA endorsement or affiliation. Because this dataset reformats and converts the original NOAA data, it should not be represented as original, unaltered NOAA data.
