  • Submit Your ENA Papers Now for Joint Special Journal Issue

    Papers using data from ARM’s Eastern North Atlantic atmospheric observatory are being accepted for a joint special issue on marine aerosols, trace gases, and clouds over the North Atlantic. Scientists have a new outlet for publishing papers that use data from the Atmospheric Radiation Measurement (ARM) user facility’s Eastern North Atlantic (ENA) atmospheric observatory. The…

  • Large-Scale Forcing Data Released for ACE-ENA Campaign

    (Left) The map shows the variational analysis domain (enclosed by the red line) for the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign. The domain is centered at ARM’s Eastern North Atlantic (ENA) atmospheric observatory on Graciosa Island. (Right) Sample plots show domain-averaged surface precipitation from the ENA rain gauge and…

  • New Radiation Data Quality VAP Release for Eastern North Atlantic

    Seen at ARM’s Eastern North Atlantic atmospheric observatory, sky radiometers on stand for downwelling radiation are among the instruments that contribute to the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product. A new level 2 (c2/s2) release of the Data Quality Assessment for ARM Radiation Data (QCRAD) value-added product (VAP) is now available…

  • ARM Best Estimate Data Sets Released for Eastern North Atlantic

    ARMBEATM relative humidity (top) and surface precipitation (bottom) are shown from ARM’s Eastern North Atlantic (ENA) atmospheric observatory in 2018. The Atmospheric Radiation Measurement (ARM) user facility provides tailored datastreams known as ARM Best Estimate (ARMBE) data products for use in the evaluation of global earth system models (Xie et al. 2010). Two ARMBE data…

  • VAP for 3-Channel Microwave Radiometer Retrievals Released to Production

    This Microwave Radiometer Retrievals version 2 (MWRRETv2) quicklook image is from Oliktok Point, Alaska, on February 8, 2018. From top to bottom, panels show observed brightness temperatures at 23.8 (blue), 30 (red), and 89 GHz (green); physically (red and blue) and statistically (green) retrieved precipitable water vapor; physically (red and blue) and statistically (green) retrieved…

  • 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)…
