Estimating drizzle drop size and precipitation rate using two-colour lidar measurements [PDF]
, 2010 A method to estimate the size and liquid water content of drizzle drops using lidar measurements at two wavelengths is described. The method exploits the differential absorption of infrared light by liquid water at 905 nm and 1.5 μm, which leads to a ...
