WebIce and snow generally show a high degree of reflection at visible wavelengths (VIS; ca 0,4 – 0,75 µm), lower reflection in the NIR (Near InfraRed, wavelength ca 0,78 - 0,90 µm) and … The radar reflectivity factor (Z) of precipitation is dependent on the number (N0) and size (D) of reflectors (hydrometeors), which includes rain, snow, graupel, and hail. Very sensitive radars can also measure the reflectivity of cloud drops and ice. For an exponential distribution of reflectors, Z is expressed by: As rain droplets have a diameter on the order of 1 millimetre, Z is in mm m (μm ). By dividing Z wi…
