  1. Micro- Rain- RadarLocal Area Weather Radar Cloud Radar Gerhard Peters Meteorological Institute University Hamburg

  2. MRR (Micro Rain Radar) characteristics

  3. Top: Time-diameter cross section of slope of spectral rainrate The red lines indicate spectral maxima The red lines indicate height of melting layer Bottom: Time-height cross section of rain rate Spectral Modes

  4. Integral Modes 1 spectral maximum 2 spectral maxima

  5. LAWR characteristics Based on Nautical Radar Furuno, Type FR7112 Fan-beam-antenna replaced by pencil beam (Offset Parabol, 85 cm) Polarization: Horizontal Scan Rate: 24 rpm X-Band Transceiver: Fixed to Antenna Unit Transmit power: 12 kW peak Frequency: 9410 ± 30 MHz (X-Band) Pulse width, Pulse repetition rate0.08 µs/2100 Hz 0.3 µs/1200 Hz 0.8 µs/600 Hz Sampling Rate 10 MHz (corresponds to 15 m range resolution) Digital power resolution 0.005 dB Dynamic range 70 dB Beam width 2.5 ° (3dB 1 way) Antenna Gain > 30 dBi Beam Elevation: +3° to + 20° (adjustable). Sensitivity: 0 dBZ, (5 km range, 0.08 µs pulse width, 30 s time integration, 60 m range integration, 2° azimuth integration)
