NCDC data are now free of charge for download! Each station on the map below points to the NCDC and WRCC. This is the same historical data that existed on previous versions of the OCS website.
The map below shows the location of National Weather Service Cooperative Observer (COOP) stations. This network of volunteer observers records daily temperature and precipitation to the National Weather Service. These data are then quality controlled and archived by the National Climatic Data Center (NCDC).
NCDC publishes data for download. Clicking on a station below will lead you to the station page at NCDC, and also the Western Regional Climate Center (WRCC) page for that station. The WRCC provides normals, station records, metadata and other plots using the archived climate data.
Other climate networks also archive data.
For real time observations (NWS, RAWS, SNOTEL):
