Barograms / Barograph Charts

EV2 - Barograms

browse graphicImage example
Barograms are weekly rectangular charts recording barometric pressure at a given station. The barograph is an instrument that makes a continuous pen and ink trace of the changing atmospheric pressure on a chart. The barograph chart is also called a barogram. There were also measurements made using other types of barometers, and recorded on paper forms. Pressures were in millibars or inches of mercury. Many of these barograms and forms were provided to the archive by U.S. agencies: National Weather Service (NWS), Federal Aviation Administration (FAA), U.S. Air Force Air Weather Service (AWS), and the U.S. Navy Weather Service. The archive includes barograms and forms from other sources, including merchant ships at sea.The archive has hundreds of thousands of barograms in physical media (primarily microfilm, though also includes microfiche and paper). The period of record begins in the late 19th century, spans the entire 20th century, and continues, though in smaller volume, into the present. A limited selection of scanned barograms are available digitally as well.

Lineage information for: dataset
Lineage Statement Limited in-house scanning activities and partnerships with other NOAA line offices and international weather services have contributed to the broad and global nature of digitally imaged records available from the archive. Charts derive from many governmental and private organizations. A limited selection of this massive collection are available digitally; the digital collection spans years 1906-1989, though most forms are from the 1940s.
Processor
  • NCDC Climate Data Modernization Program
Processing Steps
  • Digital data were scanned as JPG, TIF, or PDF from the analog forms.
    Rationale: To digitize collection in order to make available online.
Processing Environment Paper forms captured digitally using various types of scanning equipment. All forms were scanned using a minimum of 300 dpi (standard archive quality).
