U.S. Daily Surface Data (COOP Daily/Summary of Day)

browse graphicSurface Data, Daily GIS image
U.S. Daily Surface Data consists of several closely related data sets: DSI-3200, DSI-3202, DSI-3206, and DSI-3210. These are archived at the National Climatic Data Center (NCDC). U.S. Daily Surface Data is sometimes called cooperative data or COOP, named after the cooperative observers that recorded the data. In any one year there are about 8,000 stations operating. Most cooperative observers are state universities, state or federal agencies, or private individuals whose stations are managed and maintained by the National Weather Service. Each cooperative observer station may record as little as one parameter (precipitation), or several parameters. U.S. Daily Surface Data is also called Summary of the Day data. The original data was manuscript records, the earliest of which are from the 1800s. Records for approximately 23,000 stations have been archived from the beginning of record through the present. Official surface weather observation standards can be found in the Federal Meteorological Handbook.

Lineage information for: dataset
Lineage Statement U.S. Daily Surface Data consists of several closely related data sets: DSI-3200, DSI-3202, DSI-3206, and DSI-3210. See processing steps and documention for more information.
Processing Steps
  • Selected Summary of the Day data from related file DSI-3210 for National Weather Service "first order" or principal climatological stations and "second order" stations have been merged into this file. Therefore, users must be aware that if an element in DSI-3210 was flagged as suspicious or in error and an estimated value is included, the estimated value is entered into DSI-3200 as an "original" value. If a user needs the true original value, it must be retrieved from DSI-3210. It must also be noted that observations from DSI-3210 contains surface observational data from the Automated Surface Observing System (DSI-3211). Users must be aware that DSI-3210 contains flagged data that have been quality controlled by personnel at the NCDC. DSI-3211 contains only automated quality controlled data.
