The global daily meteorological station data serves as a valuable source of worldwide weather data, spanning from 1929 to the present, with the most complete data available from 1973 onwards. The latest daily data summaries are published 1-2 days after the observation date and time. Daily data types include precipitation (0.01 inches), along with mean temperature (0.1°F), maximum temperature (0.1°F), minimum temperature (0.1°F), average wind speed (0.1 knots), maximum sustained wind speed (0.1 knots), maximum gust wind speed (0.1 knots), and snow depth (0.1 inches).

The global daily meteorological station data provided by CnOpenData encompasses meteorological observations from over 9,000 stations worldwide, equivalent to a climatic census in scale. This dataset is critical for monitoring climate change and supporting climate-sensitive sectors.
