The stations used include those from the NWS Cooperative Observer Program (COOP) Network as well as some additional stations that have a Weather Bureau Army-Navy (WBAN) station identification number, including stations from the U.S. Climate Reference Network (USCRN) and other automated observation stations. In addition, precipitation normals for stations from the U.S. Snow Telemetry (SNOTEL) Network and the citizen-science Community Collaborative Rain, Hail and Snow (CoCoRaHS) Network are also available. The Daily Climate Normals dataset includes various derived products such as air temperature normals (including maximum and minimum temperature normals, heating and cooling degree day normals, and others), precipitation normals (including precipitation and snowfall totals, and percentiles, frequencies and other statistics of precipitation, snowfall, and snow depth), and agricultural normals (growing degree days (GDDs)). All data utilized in the computation of the 2006-2020 Climate Normals were taken from the Global Historical Climatology Network-Daily, but the Daily Normals are adjusted so that they are consistent with the Monthly Normals. The source datasets (including intermediate datasets used in the computation of products) are also archived at NOAA NCEI. A comparatively small number of station normals sets (~50) have been added as Version 1.0.1 to correct quality issues or because additional historical data during the 1991-2020 period has been ingested. NOAA NCEI and NOAA NWS will be primary users of this dataset. Other users include many federal, state, and local government agencies; corporations and individuals in all U.S. Economic Sectors, and the general public. The archived data will be be used to compare local climates across the United States. It will also be used to place current observations in context by allowing the calculation of anomalies (differences from normals) from a consistent reference period of record.

The main body of 1991-2020 U.S. Climate Normals were produced in 2021. However, since then a small number of requests have been received from our primary partner, the National Weather Service, for some station normals to be recalculated or added to the compilation of station normals. Reasons for these recalculations vary, but are usually accompanied by one of two causes. Either there is a correction of a flagging situation that caused a previously calculated normal to be rejected by internal quality control, or a significant amount of the underlying observational data has been replaced or added to a station record. Normals calculations follow the same procedures as used in the main production run. These new stations normals files are then tarred with the existing normals files, or used to replace existing normals files as necessary. All existing station normals that have not been replaced are carried over into Version 1.0.1. 2023-05-15T00:00:00 NOAA National Centers for Environmental Information processor asNeeded Bulk metadata change applied on 2023-07-03.
