Surface Weather Observation 1001 Forms (Keyed)

In order to fill in the observation gap prior to the time when commercial aviation began in the U.S., The NCDC Climate Data Modernization Program (CDMP) retrieved surface observations taken two to four times daily beginning as early as 1893 at the City Weather Bureau Offices. Through 1936 observations were taken twice daily; then in 1937 the general practice was to record four observations per day. Since this data overlaps with the pre-1948 hourly dataset DSI-3851 (surface airways observations) (C00623), data for each station were not keyed once their observations overlapped with the DSI-3851 data which generally contains more observations per day. The data elements are as follows: station pressure, sea level pressure, dry and wet bulb temperature, dew point, maximum and minimum temperature, wind direction and speed, precipitation, cloud amount and type, ceiling, state of weather and visibility. It should be noted that not all elements are present for all stations in this dataset, and that ceiling and visibility observations did not begin at the city offices until the 1930's. Official surface weather observation standards can be found in the Circular N manuals.

When hourly observations were not conducted, observational data from stations were keyed. These data can be found in DSI-3850 (C00622). The complimentary pre-1948 hourly observations dataset is DSI-3851 (surface airways observations) (C00623).

Use Constraints
  • NCEI cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system. NCEI makes no warranty, expressed or implied, nor does the fact of distribution constitute such a warranty. NCEI can only certify that the data it distributes are an authentic copy of the records that were accepted for inclusion in the NCEI archives.
Fees
  • In most cases, electronic downloads of the data are free, however fees may apply for data certifications, copies of analog materials, and data distribution on physical media.
Lineage information for: dataset
Lineage Statement Original observations were taken at Weather Bureau stations across the United States and sent to a central location. In the early 2000s these original forms were scanned into digital image files. From these images the data were keyed to create this dataset.
Processor
  • Climate Data Modernization Program
Processing Steps
  • A subset of information from the original data forms was keyed and incorporated into this collection.
Source Datasets
  • Monthly Weather Observations (Surface Weather Observation Forms WB-1001)

Processing Steps
  • 2015-04-22T00:00:00 - NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
