Data Announcements

The contiguous United States witnessed total solar eclipses in 2017 and 2024, and ARM now has data from both.

This product provides an automated cloud type classification based on macrophysical quantities derived from vertically pointing lidar and radar at ARM sites.

ARM users can access a reprocessed contoured frequency altitude diagram (CFAD) product from the Ka-Band ARM Zenith Radar and a new CFAD product from the high-spectral-resolution lidar.

The Atmospheric Emitted Radiance Interferometer Noise Filtered (AERINF) value-added product is now in production for recent field campaigns in California, Colorado, and Texas.

ARM’s Improved MICROBASE Product with Uncertainties (MICROBASEKAPLUS) is now available for the 2021–2022 TRacking Aerosol Convection interactions ExpeRiment (TRACER) near Houston, Texas.

Radar data collected during the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition underwent calibration, correction, and quality control processes beyond ARM’s standard quality checks and corrections.

A new ARM data epoch captures a piece of history observed during the Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE) in La Jolla, California.

To support the addition of a seventh channel to its multifilter spectral shortwave radiometers, ARM recently updated the Surface Spectral Albedo (SURFSPECALB) value-added product for two of its fixed-location observatories.

This value-added product, which uses a machine learning model that can produce pixel-to-pixel predictions of clouds in lidar images, is now available for recent field campaigns near Houston, Texas, and in northern Norway.

ARM users can access the Microwave Radiometer Retrievals (MWRRET) value-added product for the 2021–2023 Surface Atmosphere Integrated Field Laboratory (SAIL) campaign near Crested Butte, Colorado.
