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.
