  • 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…

  • New Cloud Radar Products Available for CACTI Campaign

    This shows the XSACRGRIDRHI CACTI product with two-dimensional horizontal-distance-versus-vertical-height gridded radar reflectivity when the azimuth angle is 90 degrees (east-to-west scan). The Atmospheric Radiation Measurement (ARM) user facility released new cloud radar value-added products (VAPs) from the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign. With these VAPs, scientists can more easily use corrected…

  • Cloud Microphysics VAP Evaluation Data Available for MC3E Field Campaign

    Cloud microphysical properties affect cloud radiative heating, precipitation formation, and aerosol-cloud interactions, among other important atmospheric processes. A value-added product (VAP) that calculates cloud microphysical properties now provides evaluation data for the 2011 Midlatitude Continental Convective Clouds Experiment (MC3E) in Oklahoma. The Improved MICROBASE Product with Uncertainties (MICROBASEKAPLUS) provides continuous, high time resolution profiles of…

  • Cloud Microphysics VAP Evaluation Data Available for LASIC Field Campaign

    Cloud microphysical properties affect cloud radiative heating, precipitation formation, and aerosol-cloud interactions, among other important atmospheric processes. The first field campaign data are now available from a value-added product (VAP) that builds upon the Atmospheric Radiation Measurement (ARM) user facility’s historical Continuous Baseline Microphysical Retrieval (MICROBASE) VAP. The Improved MICROBASE Product with Uncertainties (MICROBASEKAPLUS) provides…

  • LASSO Alpha 2 Supplement Includes 2015 Case Dates

    Plots from the Alpha 2 supplement show observed versus simulated cloud fraction for simulation number 13 on June 6, 2015. The plots show observed cloud fraction (top panel) retrieved from the Active Remote Sensing of CLouds (ARSCL) product using the Ka-Band ARM Zenith Radars (KAZRARSCL) product, the simulated cloud fraction (middle panel) based on large-eddy…

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

    Sample images are shown here from the KAZR-ARSCL data product for the Southern Great Plains megasite on June 4, 2013. Time-versus-height images include a) hydrometeor best-estimate reflectivity, b) cloud-layer boundaries, c) instruments contributing to hydrometeor detection, and d) hydrometeor-versus-clutter mask. Updated 3/1/2017: Data has been updated from evaluation data to baseline production data. The Active…

  • New ARM Cloud ARSCL Evaluation VAPs Available

    Sample images from the KAZR-ARSCL VAP are showing: a) hydrometer best-estimate reflectivity, b) cloud layer boundaries, c) instruments contributing to hydrometer detection, and d) hydrometer versus clutter mask. New value-added products (VAPs) have been developed to provide best-estimate radar moments and cloud locations for the Ka-band ARM Zenith Radars (KAZRs).  The KAZR Active Remote Sensing…

  • New Radar Data Lead to New Value-Added Product

    This sample KAZR-ARSCL plot shows data from the SGP on April 26, 2011. The top image shows the ‘reflectivity_best_estimate’ field, and the lower image shows cloud base and cloud top heights for all cloud layers detected on this day.The Ka-band ARM zenith radars (KAZRs) have replaced the long-serving millimeter-wavelength cloud radars (MMCRs). As a result,…
