30 Years of ARM Data

Connecting ARM’s past to its future

The Atmospheric Radiation Measurement (ARM) user facility marked 30 years of atmospheric data collection in May 2022. ARM collected its first data on May 16, 1992, in a farm field in Oklahoma. Since that date, ARM has pulled in more than 3 petabytes of data from all seven continents and all five oceans.

From May 2022 to May 2023, ARM published an “ARM30” series of articles, which reflected on the science impacts of ARM data over the past 30 years while looking ahead to the facility’s future. This page includes features from the ARM30 series, plus images, videos, and other articles that provide a view of ARM’s past, present, and future.
