The Bankhead National Forest (BNF) atmospheric observatory is a long-term mobile observatory being established by the Atmospheric Radiation Measurement (ARM) user facility in northwestern Alabama. The BNF is currently expected to be operational for five years, starting in 2024.

The main site and three supplemental sites are now operating and collecting data. Tower and scanning radar sites are also planned as part of the BNF.

Scientists will use BNF data to learn about clouds, aerosols, and land-atmosphere interactions, which in turn will lead to improvements in models of the Earth’s climate.
