How to Obtain Official Climate Data
The National Climatic Data Center and the Midwestern Regional Climate Center fill various requests for climate data. These centers are responsible for monitoring and maintaining a large number of data sets for the National Weather Service and other organizations. Weather Service Forecasts Offices are responsible for archiving weather conditions for the past 30 days and then transmitting that information to the climate centers where the official archives are maintained.
