New Aerosol Optical Depth Data Available for TRACER Campaign
The Aerosol Optical Depth (AOD) value-added product derived from 7-channel multifilter rotating shadowband radiometer (MFRSR) measurements is now available for the 2021–2022 TRacking Aerosol Convection interactions ExpeRiment (TRACER). AOD is the measure of the total aerosol burden in a vertical column of the atmosphere. The value-added product, known as AOD-MFRSR, reports cloud-screened AOD from the…

Large-Scale Forcing Data Released for SAIL Campaign
Continuous large-scale forcing data are now available for the Surface Atmosphere Integrated Field Laboratory (SAIL) field campaign. The Atmospheric Radiation Measurement (ARM) user facility conducted the SAIL campaign in high-altitude complex terrain near Crested Butte, Colorado, from September 2021 to mid-June 2023. Scientists can use this value-added product (VAP), known as VARANAL, to drive single-column…

Improved Broadband Radiation Data Available From ARM Fixed Sites
The Atmospheric Radiation Measurement (ARM) user facility processes yearly data from the Data Quality Assessment for ARM Radiation Data (QCRAD) product—the recommended ARM datastream for broadband surface irradiance measurements—to produce level 2 (c2) files. These files undergo additional processing to improve the data. New c2-level data are available for all three of ARM’s fixed-location atmospheric…

Scratching the Surface of Aerosols with Uncrewed Aerial Systems
New method helps realize the potential of uncrewed aerial systems This story was originally published on the Pacific Northwest National Laboratory website. Developing a picture of the atmosphere requires measurements from the ground and in the air. The advent of uncrewed aerial systems (UAS) has allowed researchers to develop new platforms for collecting data while…

Marine Stratocumulus Clouds Seem to Consist of Neighborhoods of Relatively Uniform Properties
Researchers show common reflective clouds are not spatially homogenous In a May 2024 article published in Science, scientists from Michigan Technological University, the College of Charleston, and Pacific Northwest National Laboratory in Washington state explore long-held assumptions about the microphysical structure of marine stratocumulus clouds. In the study, they show that droplet size distributions are…
