U.S. Surface Data Keyed from the Climate Database Modernization Program (CDMP)

  • U.S. Surface Data Keyed from the Climate Database Modernization Program (CDMP)
  • NCAR_DS506.0
  • This data set contains U.S. station surface observations that were digitized from the original forms by the Climate Database Modernization Program (CDMP). Data are available for more than 200 stations (mainly at airports, but also some city weather bureau offices) that made observations at hourly intervals at least during the daytime hours and often over the full 24-hour day. The general period of record for these stations is 1928-1948, though this varies by individual station. To find out what is available, see this inventory []. A significant effort was made by DSS to correct errors in the digitized data, especially dates, times, and pressures. For more information about this work, see this document []. We have also received data for more than 130 U.S. stations that were digitized from Form 1001. These stations, which were usually city weather bureau offices, generally took observations once, twice, or four times daily. Some stations have data back as far as late 1892. An inventory [] can be viewed which shows stations and their date range coverage. These data will be made available to the community when errors in the digitized data have been corrected.
