Continuous data and measurements from recent intensive operations, including ArcticShark uncrewed aerial system flights, are available from ARM’s atmospheric observatory in Alabama.

ARM.gov has gotten a refresh after more than eight years with its previous look. Peruse the site's new features!

More instruments are going up at ARM’s newest long-term atmospheric observatory, and science activity is increasing.

This value-added product calculates clear-sky irradiance in shortwave and longwave surface fluxes from measured broadband irradiance at ARM sites.

The Aerosol Optical Properties (AOP) value-added product is now available for ARM’s Bankhead National Forest atmospheric observatory in Alabama and the Coast-Urban-Rural Atmospheric Gradient Experiment (CoURAGE) in the Baltimore, Maryland, area.

The multipurpose ARM trajectory (ARMTRAJ) value-added product now consists of six trajectory data sets to support atmospheric research using ARM data.

This study provides a methodology to propagate the uncertainties of geophysical variables retrieved from multiple remote sensors in order to estimate the information content of derived quantities. A practical example is provided for water vapor and temperature advection fields derived from remotely sensed temperature, water vapor, and wind profiles.

This work demonstrates a new technique for estimating higher-order statistics (e.g., variance, skewness, covariance) from high-temporal-resolution ground-based lidar data, where the data is normalized to the height of the convective boundary layer (CBL) before the statistics are computed.

Even at 1-km resolution, numerical weather prediction models still fall within the "gray zone" where critical turbulent and cloud-microphysical processes remain under resolved.
