  • Ka-Band ARM Zenith Radar Product Resumes for 2 Sites

    This set of plots illustrates the KAZRARSCL product. From top to bottom are time-versus-height plots of cloud boundaries, best-estimate hydrometeor reflectivity, and dealiased mean Doppler velocity for a sample date at Oliktok Point, Alaska. The Atmospheric Radiation Measurement (ARM) user facility has resumed production of the Ka-Band ARM Zenith Radar Active Remote Sensing of CLouds…

  • ACE-ENA Spotlight: Capturing the 4-Dimensional Variability of Shallow Precipitation

    Editor’s note: This is the third entry in a blog series about ARM’s Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign, which took place during 2017 and 2018. Pavlos Kollias, an ACE-ENA co-investigator from Stony Brook University, shares a new set of precipitation findings from the air- and ground-based campaign. Figure 1:…

  • Play Us a Sad Song: Longtime ARM Manager Paul Ortega Retires

    Colleagues share their parting words Editor’s note: Kirsten Shaw Fox, communications and external affairs at Los Alamos National Laboratory in New Mexico, sent in this post. Paul Ortega removes C-Band Scanning ARM Precipitation Radar panels from the Tropical Western Pacific site on Manus Island, Papua New Guinea. Photos are courtesy of Los Alamos National Laboratory…

  • ACE-ENA Spotlight: Measuring How Clouds Respond to Seasonal Aerosol Changes

    Editor’s note: This is the second entry in a blog series about ARM’s Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign, which took place during 2017 and 2018. Rob Wood, an ACE-ENA co-investigator from the University of Washington, shares a new set of findings from the air- and ground-based campaign. Every spring,…

  • ACE-ENA Spotlight: Illuminating Seasonal Aerosol Differences

    Editor’s note: This is the first entry in a blog series about ARM’s Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign, which took place during 2017 and 2018. ACE-ENA Principal Investigator Jian Wang, Washington University in St. Louis, provides a campaign overview and writes about aerosol findings from the air- and…

  • 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…
