The Midwestern Regional Climate Center (MRCC) serves as a regional data archiving facility in cooperation with the National Centers for Environmental Information (NCEI) and other federal, state, and local authorities. As such, the MRCC can certify copies of climate records archived at the MRCC. As an archiving facility, the only fact the MRCC can attest to is that exact duplicates of climatic records on file at this center have been provided to those that requested such data. This is accomplished by attaching a cover letter to the climate data signed by a climatologist stating the authenticity of the data provided.

MRCC certified records are only available in paper format. Delivery is usually by U.S. Mail. Rush delivery by UPS is also available for an additional $25 fee.
