  • Precipitation Radar Data Product Released for CACTI Campaign

    A new CACTI data product will help users analyze information from the deployment of the second-generation C-Band Scanning ARM Precipitation Radar (CSAPR2) in Argentina. Photo is by Janek Uin, Brookhaven National Laboratory. The Corrected Moments in Antenna Coordinates Version 2 (CMAC2) value-added product (VAP) has been updated to work with the second-generation C-Band Scanning ARM…

  • 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…

  • New VAP Released for ARM Precipitation Radars

    The top image shows an application chain for CMAC2. As better algorithms become available, they can be used in the modular CMAC2 architecture. The bottom image provides an example of a CMAC2 gate ID, which is used to determine the conditional application of radar data processing. Raw data from the Atmospheric Radiation Measurement (ARM) user…

  • Scanning Precipitation Radar Data Corrected and Standardized in New Evaluation Product

    a) Attenuation corrected reflectivity filtered for second trip returns. b) Rainfall rates calculated from specific attenuation. Click to enlarge.Raw moments from the scanning ARM precipitation radars (SAPRs) are subject to a number of instrument and atmospheric phenomena that must be retrieved and corrected for. The Corrected Moments in Antenna Coordinates (CMAC) value-added product contains both…
