Marshall Radar Observatory, McGill University author NSF National Center for Atmospheric Research publisher The C-band radar aboard the Canadian ship C.C.G.S. Quadra collected reflectivity data at 1 degree by 1 km resolution at various antenna tilt angles. A single 360-degree scan at a fixed tilt angle took approximately 20 seconds to complete. A Digital Video Integrator and Processor (DVIP) converted the analog reflectivities to 8-bit digital values. The center of the first gate was 10.5 km from the radar, with equivalent reflectivities recorded for 200 gates in the radial direction. NCAR received the binary-format Quadra radar data on half-inch magnetic tapes from the Radar Weather Observatory at McGill University in April 1977. The raw reflectivity data were converted to netCDF format in 2024, and additionally, netCDF files containing full scans (sweeps) at each tilt angle are planned for later 2024, with equivalent reflectivity values converted to dBZ. completed datahelp@ucar.edu pointOfContact notPlanned dataset https://gdex.ucar.edu/images/ds_logos/gate_346_387.gif Logo thumbnail from URL gif NetCDF dataset Resource Type 2021-03-30 revision 4.4 DataCite Metadata Working Group orginator resourceTypeGeneral MOVING SHIPS Ships U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Platforms C-BAND RADAR > C-Band Imaging Radar U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Instruments GATE > GARP Atlantic Tropical Experiment U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Projects EARTH SCIENCE > SPECTRAL/ENGINEERING > RADAR > RADAR REFLECTIVITY U.S. National Aeronautics and Space Administration Global Change Master Directory GCMD 2026-02-27 revision 23.4 NASA Global Change Master Directory orginator Valids List: Science and Services Keywords Creative Commons Attribution 4.0 International License None eng utf-8 oceans 1974-06-28 1974-09-19 NSF NCAR Geoscience Data Exchange datahelp@ucar.edu https://gdex.ucar.edu distributor 6928.078 https://gdex.ucar.edu/datasets/d845002/ https Dataset Description Related Link information https://gdex.ucar.edu/datasets/d845002/dataaccess/ https Data Access Related Link download none asNeeded
