ARM User Facility

s on Earth’s energy balance. This strategy revolutionized scientists’ ability to collect long-term statistics of detailed cloud properties and now serves as a model for similar programs around the world. ARM provides:

• Data – Access more than 30 years of atmospheric data gathered from fixed-location observatories and field campaigns

• Observatories – Use heavily instrumented fixed-location atmospheric observatories in Oklahoma, Alaska, and the
Azores, including aerial (crewed and uncrewed) and mobile facilities

​• Instruments – Explore more than 400 instruments that collect data at locales spanning diverse meteorological regimes

• Campaigns – Conduct atmospheric science in strategic locations around the world

• Models – Retrieve large-eddy simulation modeling data, simulations, and analysis tools

• Publications – Discover ARM-related research on clouds and aerosols, their interaction with the Earth’s energy balance, and representation in earth system models.
