When the Sun and Moon Are Not the Only Circles in the Sky
Using ARM total sky images, a university team fine-tunes its algorithm to detect ice halos When Sylke Boyd needed help finishing a longtime research project, she turned to long-term data from the Atmospheric Radiation Measurement (ARM) user facility. For 15 years, Boyd has taught at the University of Minnesota, Morris (UMM), a liberal arts college…

DOE Labs Bolster Major ARM Effort in MOSAiC Expedition
By the end of the Multidisciplinary Drifting Observatory for the Study of the Arctic Climate (MOSAiC) expedition, the Atmospheric Radiation Measurement (ARM) user facility is expected to have collected more data than any other participant. That kind of effort would not be possible without support from the U.S. Department of Energy (DOE) national laboratories that…

New VAP Released for ARM Precipitation Radars
Raw data from the Atmospheric Radiation Measurement (ARM) user facility’s precipitation radars must be corrected for atmospheric phenomena and instrument characteristics (e.g., attenuation, clutter) to retrieve precipitation properties. A new value-added product (VAP)—Corrected Moments in Antenna Coordinates Version 2 (CMAC2)—is a set of algorithms and code that does such corrections, and it also retrieves precipitation quantities…

Raman Lidar Profiles Value-Added Product Moves to Production
Gaps in our understanding of aerosols and their interactions and influence on clouds are among the main sources of energy balance uncertainties. To reduce these uncertainties in earth system models, continuous height-resolved measurements of cloud and aerosol optical properties are needed. Now in production, the Raman Lidar Profiles – Feature detection and Extinction (RLPROF-FEX) value-added…

Cloud Microphysics VAP Evaluation Data Available for LASIC Field Campaign
Cloud microphysical properties affect cloud radiative heating, precipitation formation, and aerosol-cloud interactions, among other important atmospheric processes. The first field campaign data are now available from a value-added product (VAP) that builds upon the Atmospheric Radiation Measurement (ARM) user facility’s historical Continuous Baseline Microphysical Retrieval (MICROBASE) VAP. The Improved MICROBASE Product with Uncertainties (MICROBASEKAPLUS) provides…

Oklahoma Mesonet Soil Moisture VAP Released to Production
Soil moisture is a key parameter for understanding fluxes of moisture and energy between the land and atmosphere. Around the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains (SGP) atmospheric observatory, variations in soil moisture are expected to affect land-atmosphere interactions. In support of continuing soil moisture research applications on a mesoscale level at…
