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

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 The vast majority of the digital image records available originate from the NCDC physical archives through the Climate Database Modernization Program (CDMP). These efforts produced over 50 million images from 2000-2011. Additional limited scanning activities at NCDC also contribute to the image repository. 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 NCDC.

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.
