All of the following are sources of error in gauge rainfall measurement EXCEPT

  • A.wetting losses on the internal surfaces
  • B.the sixth power dependence of reflectivity
  • C.wind induced undercatch at the gauge orifice
  • D.evaporation from the collector between readings

Answer: B

That dependence is a property of radar rather than of a gauge. The other three are the standard systematic errors in gauge measurement, of which wind undercatch is much the largest. Snow is affected far more severely than rain.
