Paragraph 1-7a describes how the Non-Federal Observing (NF-OBS) Program’s procedures and practices must meet federal standards.

The Non-Federal Observing (NF-OBS) Program was developed to enable local aviation entities such as non-federal control towers (NFCTs), airport personnel or fixed base operators (FBOs) to assist with the backup and augmentation of the ASOS. The program is region-driven with oversight provided by FAA Headquarters and is meant to be at no cost to the Government.

Upon request by a potential NF-OBS provider, each FAA region may enter into a cooperative agreement with the provider. Agreements shall define the hours of operation for the NF-OBS and the service level at which the operation will be conducted. They also contain provisions that the NF-OBS provider will provide and train observers, provide suitable storage for instruments and equipment, and provide required backup equipment. Observers shall be certified by the National Weather Service and shall make all observations in accordance with applicable regulations.

Further information about this program can be obtained from the Aviation Weather Policy Division, ARW-100.
