ARM Data Archive

Data collected through the routine operations and scientific field experiments of the ARM Climate Research Facility are stored at and distributed through the Archive. These data are available free of charge to the public and can be accessed through any of the interfaces below. Upon selection of an interface, a new window will ask you to sign in, or, if not already registered with the Archive, to complete the free and easy registration process.

Get routine ARM data

Data Discovery [ ? ]

Please try the new Archive User Interface(Beta version), featuring filtered and faceted search logic, multi-pass data selection, filtering data based on data quality, graphical views of data quality and availability, direct access to data quality reports, and data plots. Please provide any feedback or comments to armarchive@ornl.gov

Data Browser [ ? ]

Select datastreams, view quality information about the data and order data files with the Data Browser. The "Novice Interface" guides new users through the process, while the "Datastream Interface" is designed for users experienced with ARM data.

Thumbnail Browser [ ? ]

View prepared plots of data to quickly find data of interest to you. The thumbnail browser uses location, measurement type and date range selections to retrieve data plot thumbnails that the user can browse. You can also download high-resolution images of the data plots, or download the data files.

Plot previously ordered data

NCVWeb [ ? ]

NCVWeb is an interactive NetCDF data plotting tool users can use to plot the data they have ordered from the archive, or plot regular standing data orders, eliminating the need for separate visualization software. It has many powerful features such as producing detailed tables of NetCDF file contents, data extraction, generating statistics, and plotting one variable against another.

IOP Data PI Data Evaluation Data Showcase Data [ ? ]

Browse and download data generated from ARM Intensive Operation Periods or "IOPs". Data is stored in a directory structure organized by year, site, IOP name and instrument. A README file is included in each directory to provide documentation.

Note: ARM Archive is currently consolidating the user interfaces to better serve its users, as part of this effort, we recently decommissioned several of the old user interfaces. These user interfaces can be still accessed, for a limited time, at http://www.archive.arm.gov/armlogin/loginOld.jsp
