Cooperative Weather Observations

EV2 - Cooperative Observations

browse graphicImage example
Monthly logs include a daily account of temperature extremes and precipitation, along with snow data at some locations. U.S. Cooperative Observer Program (COOP) Network stations scattered across the continental U.S., a few from Caribbean and Pacific Island stations. Cooperative stations are assigned a six-digit COOPID in which the first two correspond to the state, and the last four are assigned roughly in alphabetical order by station name. For a complete list of station IDs, see the cooperative station list at http://www.ncdc.noaa.gov/homr/reports/mshr . Stations that were not a part of the network at the time the reports were submitted are assigned ID 777777

Dataset Progress Status Ongoing - data is continually being updated
Data Update Frequency Irregular
Purpose In the late 1990s NCDC realized the need to host digital images of weather and climate records on the internet. As a result, EV2 was developed as a key system for providing access to the millions of original source data images in the NCDC archives. With its upload and index capability, EV2 also enables the continuation of NCDC's commitment to make more of its weather and climate data available online so that users across the world can view climate and weather records held in the NCDC archives.
Use Limitations
  • Controlled user access to the EV2 system
