Radar Estimates of Precipitation
Danielson et al
¥Radar emits pulses of EM radiation of wavelength between 3-10 cm
¥Pulse reflects off raindrops, dust, bugs, chaff, etc.
¥Distance from radar and intensity of precipitation can be determined from radar reflectivity
Object size
can be determined from amplitude of
return pulse.
Larger objects are more reflective.
Reflections
from objects farther away take
longer to return.
