Atmospheric Radiation Measurement (ARM) User Facility

The Atmospheric Radiation Measurement user facility is a multi-laboratory collaboration that is a key contributor to national and international climate research efforts. We operate over 450 instruments across six ground-based observatories that collect data to improve our understanding of atmospheric processes and advance Earth system models. All data is freely available to the public.

Isotope ratio mass spectrometry (IRMS) leverages magnetic sector mass spectrometry to enable high-precision measurement of the stable isotope content of a sample. Typical measurements target hydrogen, carbon, nitrogen, and oxygen analyses—although elements with masses up to and including sulfur can be measured.
