ARM Archive

The ARM Archive supports the scientific field experiments of the Atmospheric Radiation Measurement (ARM) Program by storing and distributing the large quantities of data collected from these experiments. These data are used to research atmospheric radiation balance and cloud feedback processes, which are critical to the understanding of global climate change.

To order ARM data, please login to the Archive User Interface. The Interface enables ordering data from the ARM Data Browser, the Catalog Interface, the Thumbnail Browser, and the IOP Data Browser.

To order data via email or report any problems with this site, please email User Services at or call 1-888-ARM-DATA or (865) 241-4851. Thank you.
