Summary of the Day (CDMP)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 09:20 PM | Dataset Last Updated: February 01, 2005 at 12:00 AM
This Summary of the Day data file contains daily selected elements of observations recorded by certified observers. The stations were located in the U.S. and were operated by the United States Weather Bureau (later the National Weather Service) and the Federal Aviation Administration (FAA). This data file spans 1945-1948. These first and second order stations were usually fully instrumented and therefore recorded a complete range of meteorological parameters. The observations were generally recorded for the 24-HR period midnight to midnight. There are a total of 169 stations with recorded observations in this dataset. Stations have varying periods of record and varying types of data elements. In the early years of aviation most stations were located in major cities. As aviation became more sophisticated, stations shifted to airports. Official surface weather observation standards can be found in the Circular N manuals. Images from which the data originated are available on a web based system owned by the National Climatic Data Center (NCDC)
