Data Announcements

ARM recently released more than five years of historical data from the Video Disdrometer Quantities (VDISQUANTS) value-added product for the Southern Great Plains Central Facility near Lamont, Oklahoma.

Radar data collected during the TRacking Aerosol Convection interactions ExpeRiment (TRACER) have undergone calibration, correction, and quality control processes beyond ARM’s standard quality checks and corrections.

These value-added products are specifically designed for the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition, which involved the deployment of a Doppler lidar and other ARM instruments on an icebreaker.

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.
