Global Annual Weather Summaries from 1763 to Present

Annual meteorological summaries for global weather stations provide average temperature, precipitation totals, and derived metrics like degree days and extreme counts. Data spans from 1763 to the present, with weekly updates applied. The dataset is produced by NOAA NCEI using the Global Historical Climatology Network - Daily (GHCN-Daily) as its primary source.

Use Cases

• Model long-term temperature trends using average annual temperature and departure from normal fields.
• Analyze precipitation variability and drought indicators with total annual precipitation and days above/below threshold data.
• Calculate energy demand forecasts from heating and cooling degree day columns.
• Study extreme weather frequency by examining extreme annual minimum/maximum temperatures and days with thunderstorm data.

Strengths

• Time series begins in 1763, providing over 250 years of historical climate context.
• Includes global station data, expanding beyond the legacy U.S.-only COOP summaries.
• Weekly updates ensure incorporation of recent observations.

Limitations

• Specific row count, sample size, and geographic station density are not provided.
• Dataset lacks the bias-corrected temperature data available in the related GHCN-Monthly product.
• Precipitation and snowfall measurements may have varying accuracy and completeness across global stations.
