Power Your Research with ARM Data

Atmospheric Radiation Measurement (ARM) User Facility data are collected through routine operations and scientific field experiments.

Serving users worldwide, the ARM Data Center obtains and archives approximately 50 terabytes of data per month. Datastreams are generally available for download within 48 hours.

Access the Data

All data obtained through ARM are monitored for quality and made available free of charge through the ARM Data Center via Data Discovery.

ARM User Profile

As a U.S. Department of Energy national scientific user facility, ARM welcomes users from all institutions and nations. A free ARM user account profile is needed to access ARM data.

About ARM Data

ARM data include routine data products, value-added products (VAPs), field campaign data, complementary external data products from collaborating programs, and data contributed by ARM principal investigators for use by the scientific community. Data quality reports, graphical displays of data availability/quality, and data plots are also available from the ARM Data Center.

Data Collection and Processing Resources

Submit Data to ARM

The ARM Data Center hosts a variety of science data products, including data submitted by ARM users, field campaign principal investigators, and Atmospheric System Research (ASR) scientists. ARM is the preferred data archive for ASR-supported science data products.

Use ARM's Science Data Products

In addition to collecting and distributing atmospheric data, ARM develops several types of science data products. These data are curated to be useful to a broad audience, including graduate students, seasoned ARM users, retrieval experts, and high-resolution to global modelers, each with different comfort levels for working with observational data. ARM staff use their expertise with the observations to make higher-order data products that have been analyzed and processed to ease scientists’ use of ARM data.
