How far back does the data go?

GHCN-Daily records go back to the 1700s for some stations, with widespread coverage since the 1890s. Over 100,000 stations worldwide, with the densest network in the United States.

What is the difference between GHCN-D, GSOM, and GSOY?

GHCN-Daily provides day-by-day records. GSOM (Global Summary of the Month) aggregates these into monthly averages and totals. GSOY (Global Summary of the Year) provides annual summaries.

Are observations available for international locations?

Yes, while NOAA is a US agency, the GHCN incorporates data from over 100,000 stations worldwide, though the highest density remains in North America, Europe, and Australia.
