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.
