ARM's Mission and Objectives

 Show Specials

  • Meet with scientists and ARM staff to discover how to use ARM data in your research. Learn about our atmospheric observatories located in diverse climatic regions and field campaigns conducted around the world. Data are freely available in ARM’s new Data Discovery browser, which provides comprehensive details about datastreams and availability of new data through a guided search. ARM staff will provide tutorials on the new Data Discovery during regular exhibit hours.

  • Atmospheric Data from ARM
    ARM user facility data are collected through routine operations and scientific field experiments. ARM obtains continuous measurements—supplemented by field campaigns—from climatically diverse regions....

  • Serving users worldwide, the ARM Data Center collects and archives approximately 20 terabytes of data per month, including routine data products, value-added products (VAPs), field campaign data, and data contributed by ARM principal investigators for use by the scientific community. These long-term measurements of cloud and aerosol properties, radiative energy, meteorology, precipitation, and surface properties from diverse locales can be used to study atmospheric processes and improve earth system models.
