Atmospheric Observatories

 

Three heavily instrumented fixed-location atmospheric observatories that represent a broad range of conditions are operated by the Atmospheric Radiation Measurement (ARM) user facility to gather massive amounts of atmospheric data. These are:

Mobile and Aerial Observatories

In addition to the fixed-location observatories, ARM also offers both mobile and aerial facilities:

  • ARM Mobile Facility (AMF): Three AMF are used by scientists to obtain atmospheric measurements, similar to those at the fixed-location observatories, for periods of about a year at a time anywhere in the world. The third mobile facility is currently undergoing an extended deployment at Oliktok Point, Alaska.
  • ARM Aerial Facility (AAF): The AAF obtains aerial measurements in the skies above the fixed-location and AMF observatories. The AAF has purchased a Bombardier Challenger 850 regional jet to expand ARM’s scientific data capabilities. The Challenger 850 is expected to be ready for its first ARM campaign by fiscal year 2022 or 2023. ARM is also developing unmanned aerial system and tethered balloon capabilities to address a wide range of science requirements.

Past Observatories

Data from past deployments of the AMF and AAF, and the former Tropical Western Pacific (TWP) observatory, are a valuable asset to researchers worldwide and are easily accessible from the ARM Data Center through Data Discovery.
