  • 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…

  • Microwave Radiometer Retrieval Evaluation Data Available for Eastern North Atlantic

    The 3-channel microwave radiometer provides time-series measurements of brightness temperatures from three channels, which are sensitive to the presence of liquid water and precipitable water vapor. Evaluation data for the Microwave Radiometer Retrievals version 2 (MWRRETv2) value-added product (VAP) have been processed for the Atmospheric Radiation Measurement (ARM) user facility’s Eastern North Atlantic (ENA) atmospheric…

  • KASACR Data Quality Masks Value-Added Product Now Available in Evaluation

    Evaluation data for the Ka-Band Scanning ARM Cloud Radar (KASACR) Data Quality Masks are now available from the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign conducted in June and July 2017. The specific dates covered in this data set are June 18 through July 31, 2017. Data quality masks help…

  • Aerosol Optical Properties VAP Now Available

    The first plot shows the aerosol extensive property of light absorption for nominally “red,” “green,” and “blue” light over a two-week period at Ascension Island. The second plot shows the wavelength dependence of aerosol absorption—an intensive property—which describes the nature rather than the abundance of the absorption. The Aerosol Optical Properties (AOP) value-added product (VAP)…

  • Two New Data Products Available from the Radar Wind Profiler

    Time-height images are shown here of the wind speed at a uniform 10-minute and 50-meter resolution from the radar wind profilers, part of the instrumentation at four observing facilities at the Southern Great Plains megasite. The facility name is shown in the top left corner in each panel. The ceilometer-recorded first cloud base height (red)…
