  • Characterized and Calibrated Radar Data Now Available for TRACER Campaign

    This map indicates the Houston-area radar locations during TRACER, including those of the second-generation C-Band Scanning ARM Precipitation Radar (CSAPR2), Ka- and X-band scanning ARM cloud radars (SACR), and Ka-Band ARM Zenith Radar (KAZR). ARM’s radar team cross-compared data from the ARM and NOAA NEXRAD Houston/Galveston (KHGX) radars to help determine reflectivity offsets. Map was…

  • TRACER Cell Tracking Data Shed Light on Convective Evolution

    Using data from the second-generation C-Band Scanning ARM Precipitation Radar (CSAPR2), the panels provide reflectivity (a, c, e, g) and Doppler velocity (b, d, f, h) processed from three range-height indicator scans (a–f) and the lowest plan position indicator scan (g, h) during the TRacking Aerosol Convection interactions ExpeRiment (TRACER) on August 17, 2022, in…

  • Convective Cell Tracking Database Now Available for CACTI Campaign

    A new database describes the properties of individually tracked convective cells during the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign. The Atmospheric Radiation Measurement (ARM) user facility conducted the CACTI campaign in 2018 and 2019 in Argentina’s Sierras de Córdoba mountain range. Using data from the second-generation C-Band Scanning ARM Precipitation Radar (CSAPR2)…

  • New Value-Added Products Released for Scanning ARM Precipitation Radars

    Indicating a storm moving through ARM’s Southern Great Plains intermediate facility I5 at Garber, Oklahoma, on October 5, 2017, sample plots from the Quasi-Vertical Profiles product show azimuthally averaged X-Band Scanning ARM Precipitation Radar data as a function of time and height. Sample Velocity Azimuth Display product plots from the same October 2017 storm at…

  • Unique Manus Island Precipitation Data Available

    Statistical coverage product from the Manus C-SAPR showing times of data availability. Click to enlarge. Evaluation data are available for the value-added product (VAP) Mapped Moments to a Cartesian Grid (MMCG) for periods between October and December 2011 from the Tropical Western Pacific Manus site. The C-band Scanning ARM Precipitation Radar (C-SAPR) produces measurements of…

  • Mapping for Precipitation Radar Data Ready for Evaluation

    These images of MMCG data show three perspectives (slices) of corrected CSAPR reflectivity from a fixed location: (top) horizontal slice at a constant altitude; (middle) vertical slice along a constant longitude; (bottom) vertical slice along a constant latitude.The first-ever 4-dimensional ARM data product, called Mapped Moments to a Cartesian Grid (MMCG), is now available for…
