Data Announcements

New data are available from Alaska, California, Colorado, Oklahoma, and Texas. More samples are currently being collected in Tasmania for analysis.

The Aerosol Optical Depth (AOD) value-added product derived from 7-channel multifilter rotating shadowband radiometer (MFRSR) measurements reports cloud-screened AOD from the direct normal irradiance measured by MFRSRs at ARM’s ground-based sites.

Scientists can use the VARANAL value-added product from the Surface Atmosphere Integrated Field Laboratory (SAIL) campaign to drive single-column models, cloud-resolving models, and large-eddy simulation models for different cloud and convective systems.

New c2-level data from the Data Quality Assessment for ARM Radiation Data (QCRAD) product are available for all three of ARM’s fixed-location atmospheric observatories.

Aerosol Optical Depth Best Estimate 5-Channel (AODBE5CH) production data are now available for the Eastern North Atlantic and Southern Great Plains atmospheric observatories.

The Point Cloud of Cloud Points (PCCP) value-added product is now available for the 2021–2022 TRacking Aerosol Convection interactions ExpeRiment (TRACER) in the Houston, Texas, area.  

Merging aerial and ground-based data, these products make it easier to use measurements from ARM tethered balloon system flights.

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.
