Capabilities

Scientists from around the world have access to a wide range of resources from the Atmospheric Radiation Measurement (ARM) User Facility to conduct atmospheric research.

Atmospheric Observatories

Three fixed-location atmospheric observatories operate continually to measure cloud and aerosol properties and their impacts on Earth’s energy balance. Scientists use these observatories, along with the ARM mobile and aerial observatories, to obtain long-term and episodic measurements of radiative fluxes, cloud and aerosol properties, precipitation, and related atmospheric characteristics in a broad range of atmospheric and environmental conditions.

Instruments

A comprehensive suite of cutting-edge instrumentation deployed at ARM atmospheric observatories is designed specifically to measure clouds, aerosols, radiation, and the interactions among them.

In addition to ARM’s extensive collection of instruments, some information is provided about guest and external instruments owned and operated by other programs. All instruments are categorized by measurable properties to support searching.
