  1. Identify how the variables below impact the size of the radar beam, the strength of the radar pulse, and the resulting values of Reflectivity:
    1. Range from the radar
    2. Transmitted power
    3. Drop-size distribution
  2. Identify the resolution (i.e., range and azimuth) and precision (e.g., 3-bit, 4-bit, or 8-bit) values for WSR-88D base products
  3. Identify the difference between radar sensitivity and calibration.
  4. Identify the definition and radar product impacts of attenuation, differential attenuation, and non-uniform beam filling.
  5. Identify the definition of the Doppler dilemma, the definition of range folding, and the relationship pulse repetition frequency (PRF) has on calculations of target range and velocity.
  6. Identify two situations where sidelobe contamination is likely to occur.
  7. Identify meteorological conditions conducive to superrefraction and subrefraction of the radar beam, and the resultant operational impacts.
  8. Identify the azimuthal width that defines super resolution and legacy base data and the VCP waveform that is necessary to generate super resolution base data.
