New Radiation Data Quality VAP Release Available for Southern Great Plains
Radiometers collect data at the ARM Southern Great Plains extended facility E31 (Anthony, Kansas). A new level 2 (c2/s2) release for the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product (VAP) is now available. This release covers the following 13 extended facilities at the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains…

New VAP Released for ARM Precipitation Radars
The top image shows an application chain for CMAC2. As better algorithms become available, they can be used in the modular CMAC2 architecture. The bottom image provides an example of a CMAC2 gate ID, which is used to determine the conditional application of radar data processing. Raw data from the Atmospheric Radiation Measurement (ARM) user…

Raman Lidar Profiles Value-Added Product Moves to Production
The figure shows the aerosol extinction coefficient and its uncertainties at ARM’s Eastern North Atlantic atmospheric observatory on July 21, 2019. 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 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
The figure shows volumetric water content for the Oklahoma Mesonet Butler station during 1998 at four subsurface levels. 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…

U.S. Mesoscale Convective System Database Now Available to Help Improve Atmospheric Models
A snapshot of the pixel-level mesoscale convective system (MCS) database from May 12, 2011, shows (a) infrared brightness temperature and (b) radar reflectivity at 2-kilometer mean sea-level height. In panel (b), the color shadings behind large clusters of radar echo denote MCS masks, while the gray shadings indicate regions with no radar coverage at 2-kilometer…

Evaluation Data Available From MARCUS Navigation and Ship Correction VAPs
Figure a shows the MARCUS ship’s track—color-coded by day—from January 16 to 26, 2018. The minimum, the 25th percentile, the median, the 75th percentile, and the maximum beam angle (angle off the zenith) are represented by box-and-whisker plots in figure b, whereas the colors of the boxes correspond to the days on the map in…

New VAP Available for Atmospheric Emitted Radiance Interferometer
The figure shows a time series of temperature, relative humidity, and water vapor mixing ratios retrieved from AERIOE. Retrievals are from ARM’s Southern Great Plains Central Facility on June 11, 2017. The Atmospheric Emitted Radiance Interferometer Optimal Estimation (AERIOE) value-added product (VAP) is a new data product that provides boundary layer profiles of temperature and…
