These stations are now largely automated, and are usually part of the Automated Surface Observing System (ASOS) or Automated Weather Observing System (AWOS). The hourly normals include temperature, dew point, heat index, wind chill, wind, cloudiness, heating and cooling degree hours, pressure normals, and other statistics of these variables. Users can access the data either by product or by station. All data utilized in the computation of the 1991-2020 Climate Normals were taken from the Integrated Surface Dataset (ISD) Lite (a subset of NCEI's Integrated Surface Dataset). These source datasets (including intermediate datasets used in the computation of products) are also archived at the NOAA NCEI. 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.
