NOAA SSODv2 – Global Daily Data
NOAA SSODv2 overview
SSODv2 is the global daily archive inside Climate Explorer. It provides global UTC-aligned temperatures, wind, and precipitation records from over 9,000 stations.
Curated by NOAA NCEI, the dataset aligns all aggregations to a UTC calendar day (00:00 to 23:59 UTC) rather than local climatological days, making it essential for global comparisons.
Looking for data for your country?
This dataset contains meteorological records for every country in the world. If you do not see a dedicated dashboard for your specific region elsewhere on Climate Explorer, you will find the data here.
For sub-daily or hourly observations, check out the GHCNh Explorer.
