Atmospheric Radiation Measurement (ARM) Climate Research Facility (ACRF) (ACRF)

Updated 2012-07-25

The Atmospheric Radiation Measurement (ARM) Climate Research Facility (ACRF) is a multi-platform national scientific user facility, with instruments at fixed and varying locations around the globe for obtaining continuous field measurements of climate data. Each ACRF site uses a leading edge array of cloud- and aerosol-observing instruments to record long-term continuous atmospheric and surface properties that affect cloud formation and radiation transport through the atmosphere. The ARCF also provides shorter-term (months rather than years) measurements with its two mobile facilities (AMFs) and its aerial measurements. Network type: - Atmosphere, with a focus on the impact of clouds and aerosol on the Earth’s radiation budget. - Location: Primary site: Barrow, Alaska, 71° 19' 23.73" N, 156° 36' 56.70" W Secondary site: Atqasuk, Alaska, 70° 28' 19.11" N, 157° 24' 28.99" W - Community-based: No.
