National Climatic Data Center
Résumé
The United States National Climatic Data Center (NCDC), previously known as the National Weather Records Center (NWRC), in Asheville, North Carolina, was the world's largest active archive of weather data. Starting as a tabulation unit in New Orleans, Louisiana in 1934, the climate records were transferred to Asheville in 1951, becoming named the National Weather Records Center (NWRC). It was later renamed the National Climatic Data Center, with relocation occurring in 1993. In 2015, it was merged with the National Geophysical Data Center (NGDC) and the National Oceanographic Data Center (NODC) into the National Centers for Environmental Information (NCEI).
In 1934, a tabulation unit was established in New Orleans, Louisiana to process past weather records. Climate records and upper air observations were punched onto cards in 1936. This organization was transferred to Asheville, North Carolina in 1951, where the National Weather Records Center (NWRC) was established. It was housed in the Grove Arcade Building in Asheville, North Carolina. Processing of the climate data was accomplished at Weather Records Processing Centers at Chattanooga, Tennessee, Kansas City, Missouri, and San Francisco, California, until January 1, 1963 when it became consolidated with the NWRC. This name was maintained by the agency through 1967. The NCDC was then housed at the Veach-Baley Federal Complex in downtown Asheville where it moved after the building's completion in 1995. In 2015, NCDC merged with the National Geophysical Data Center and the National Oceanographic Data Center to form the National Centers for Environmental Information.
Data were received from a wide variety of sources, including weather satellites, radar, automated airport weather stations, National Weather Service (NWS) Cooperative Observers, aircraft, ships, radiosondes, s, rocketsondes, solar radiation networks, and NWS Forecast/Warnings/Analyses Products.
The Center provided historical perspectives on climate which were vital to studies on global climate change, the greenhouse effect, and other environmental issues.
