ARM Aerial Facility

Aerial observatory capabilities of the Atmospheric Radiation Measurement (ARM) user facility are operated by the ARM Aerial Facility (AAF). The AAF provides airborne measurements required to answer research questions proposed by scientists from around the world.

The AAF enhances surface-based ARM measurements by providing:

• in situ measurements of aerosols, clouds, and trace gases
• sampling not possible using surface- or satellite-based techniques
• measurements for validation of surface- or satellite-based techniques
• context for and extension of surface-based measurements
• measurements for testing and evaluating models.

ARM acquires airborne measurements during intensive field campaigns or long-term, regularly scheduled flights. Scientists can request these through the competitive ARM field campaign application process.

Once collected, data from the aircraft are documented, checked for quality, integrated into the ARM Data Center, and made freely available via Data Discovery for use by the scientific community.

In addition to full-sized aircraft, ARM is developing uncrewed aerial system (UAS) and tethered balloon system (TBS) capabilities to gather in situ atmospheric measurements. ARM has collected measurements from TBS and small UAS, and is now deploying a midsized UAS that provides greatly expanded capabilities in terms of payload, elevation, and endurance.
