  • 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…

  • 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…

  • 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…

  • New Precipitation Value-Added Product Released for Laser Disdrometers

    Histograms of quantities associated with convective (red) and stratiform (blue) drop size distributions (DSDs) in terms of normalized DSD intercept parameter Nw (a), liquid water content LWC versus rainfall rate R (b), and median drop size D0 versus S-band Reflectivity Factor Z (c). Density is shown on the color scale. Information is adapted from Wang…

  • Scanning ARM Cloud Radar-Velocity Azimuth Display Product Released to Production

    Horizontal wind speed and direction at cloud level, from SACR-ADV-VAD, are shown for the first seven days of August 2012 at ARM’s Southern Great Plains Central Facility. The Scanning ARM Cloud Radar-Advanced-Velocity Azimuth Display (SACR-ADV-VAD) value-added product, which provides profiles of horizontal wind estimates at cloud level, has moved to production. SACR-ADV-VAD uses radial mean…

  • New Radiation Data Quality VAP Release Available for Southern Great Plains Extended Facilities

    Radiometers collect data at the ARM Southern Great Plains extended facility E35 at Tryon, Oklahoma. A new level 2 (c2/s2) release of the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product (VAP) is now available for eight extended facilities at the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains atmospheric observatory. This…

  • REVISED: New Shallow Cumulus VAP Available

    These plots provide data about shallow cumulus events at ARM’s SGP Central Facility in June 2017. The top panel shows days with shallow cumulus events. The bottom panel gives more information for up to four events, including whether the event contained overlying cirrus, was not detected because no low clouds were found, missed the length…

  • Continuous Large-Scale Forcing Data for Cloud Modeling From Southern Great Plains Extended to October 2018

    The seasonal cycle of Southern Great Plains domain-averaged latent heat (LH) and sensible heat (SH) fluxes is shown by using QCECOR-only (QCECOR), BAEBBR-only (BAEBBR), and both QCECOR and BAEBBR data (merged) averaged from 2004 to 2015, and the impact to the derived large-scale vertical velocity (omega). Version 2 of the continuous forcing value-added product uses…

  • New Radiation Data Quality (QCRAD) VAP Release Now Available

    A broadband radiometer station at ARM’s Southern Great Plains Central Facility near Lamont, Oklahoma, measures broadband solar (shortwave) and infrared (longwave) radiation. Data from this station have been processed as part of a new release for the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product. A new level 2 (c2/s2) release for the…
