U.S. Climate Normals Product Suite (1981-2010)

browse graphicNOAA 1981-2010 U.S. Climate Normals
The NOAA Climate Normals are a large suite of data products that provide users with many tools to understand typical climate conditions for thousands of locations across the United States, including the 30-year normals, 5, 10, 15, 20-year normals, agricultural normals, and others. For nearly 100 years, the 30-year NOAA Climate Normals have been a premier NOAA product of 30-year-averages of meteorological parameters. The 1981-2010 Climate Normals Product Suite has been expanded to meet more user needs and requirements spanning many different industries, including agriculture, heating and cooling, construction, and others. To ensure both quality and completeness, hundreds of NWS stations meeting stringent criteria are used, including those from NWS's Cooperative Observer Program (COOP) Network, some additional stations are included in the Supplemental Climate Normals for 1981-2010.

Lineage information for: dataset
Lineage Statement NOAA's 1981-2010 Climate Normals are the newest iteration of the U.S. Climate Normals. Though previous versions of the normals are still available from the archive, the 1981-2010 Climate Normals should be used for all current applications. Computation of the NOAA Climate Normals is in accordance with the recommendation of the World Meteorological Organization (WMO), of which the United States is a member. While the WMO mandates each member nation to compute 30-year averages of meteorological quantities at least every 30 years (1931 - 1960, 1961 - 1990, 1991 - 2020, etc.), the WMO recommends a decadal update, in part to incorporate newer weather stations. Further, the NOAA NCDC has a responsibility to fulfill the mandate of Congress "... to establish and record the climatic conditions of the United States." This responsibility stems from a provision of the Organic Act of October 1, 1890, which established the Weather Bureau as a civilian agency (15 U.S.C. 311).
