Precipitation measured by weather radar
A) is based on the inability of falling droplets, ice crystals and hailstones to scatter radiation
B) is based on the emission of radiation by falling droplets, ice crystals and hailstones
C) is based on the absorption of radiation by falling droplets, ice crystals and hailstones
D) is based on the scattering of radiation by falling droplets, ice crystals and hailstones
Question 2

A) make them exactly as useful as precipitation measurements by radar
B) makes it difficult to determine the horizontal extent of precipitation from the measurements.
C) makes them particularly useful in determining the horizontal extent of precipitation from the measurements
D) reduces their measurement errors
