  • Improved Microwave Radiometer Retrieval Data Produced for 2 ARM Sites

    New level 2 (c2) files are now available from the Microwave Radiometer Retrievals value-added product (MWRRET VAP). This release covers 2020 and 2021 at the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains Central Facility near Lamont, Oklahoma, and 2018 through 2021 at ARM’s North Slope of Alaska atmospheric observatory. MWRRET retrieves column precipitable…

  • REVISED: New Shallow Cumulus VAP Available

    Editor’s note (October 15, 2019): Additional data for the Shallow Cumulus value-added product (VAP) have been released. Data are now available for the Southern Great Plains atmospheric observatory from July 2, 2000, through May 31, 2019. The Shallow Cumulus VAP will be run operationally on additional data from the Active Remote Sensing of Clouds using…

  • New Cloud Type VAP and Visualization Available

    A new data product—the Cloud Type Classification (CLDTYPE) value-added product (VAP)—provides an automated cloud type classification based on macrophysical quantities derived from vertically pointing lidar and radar. Up to 10 layers of clouds are classified into seven cloud types based on predetermined and site-specific thresholds of cloud top height, cloud base height, and thickness. Inputs…

  • Merged Multisensor Cloud-Precipitation Mask and Cloud Type Data Now Available for GoAmazon2014/15

    A newly available ARM principal investigator product can be used by scientists to better characterize cloud and precipitation profiles of all conditions, including during heavy precipitation from storms, as well as to validate model simulations. The Merged RWP-WACR-ARSCL Cloud Mask and Cloud Type data set for the GoAmazon2014/15 field campaign has been released for the years…

  • LASSO Alpha 2 Supplement Includes 2015 Case Dates

    The Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) team recently made available a supplement to the Alpha 2 set of data bundles, adding five case dates from spring and summer 2015. The LASSO data product consists of data bundles combining LES input and output, relevant observations, skill scores, and diagnostics. The data bundles…

  • New Release of Radar CFAD Data Product for ARM Radar Simulator

    Updated: Newly released data are now included from the Southern Great Plains, North Slope of Alaska, and Tropical Western Pacific atmospheric observatories from 2011 to 2013. Previous radar CFAD data (nsaradarcfadC1.c1) for the period between 2006 and 2010 from the North Slope observatory have been removed due to a radar calibration issue. An ARM cloud radar…

  • KAZR-ARSCL and KAZRCOR Products Now Available for 2011-2014 Data

    Updated 3/1/2017: Data has been updated from evaluation data to baseline production data. The Active Remote Sensing of Clouds product using Ka-band ARM Zenith Radars (KAZR-ARSCL) value-added product (VAP) and KAZR Corrected Data (KAZRCOR) VAP together are successors to the retired ARSCL VAP. The ARSCL VAP was based on the Millimeter Wavelength Cloud Radar (MMCR),…

  • An Update of WACR-ARSCL: Evaluation VAP Data Available

    New data sets from the 95 GHz W-band ARM Cloud Radar-Active Remote Sensing of Clouds (WACR-ARSCL) are now available for download as an evaluation value-added product (VAP) for the ARM Mobile Facility (AMF) deployments in Hyytiälä, Finland, from February through September 2014, and Manacapuru, Brazil, from January through December 2014. Evaluation data have been previously…

  • Droplet Number Concentration Value-Added Product Now Operational

    Cloud droplet number concentration is an important factor in understanding aerosol-cloud interactions. As aerosol concentration increases, it is expected that droplet number concentration will increase and droplet size will decrease for a given liquid water path. This will greatly affect cloud albedo as smaller droplets reflect more shortwave radiation; however, the magnitude and variability of…

  • Microwave Radiometer Retrieval Data Available for AMF Sites

    The Microwave Radiometer Retrievals (MWRRET) value-added product (VAP) has now been processed for the following ARM Mobile Facility (AMF) deployments: Black Forest, Germany Shouxian, China Niamey, Niger, West Africa Graciosa Island, Azores. Preliminary data are also available for the MAGIC deployment of the AMF in the evaluation area of the ARM Data Archive. The MAGIC…
