Abstract:
1. A method of determining a size distribution of water droplets in a cloud comprising: sampling a depth of a could with a beam of electromagnetic radiation, the beam of electromagnetic radiation comprising a beam emitted from a laser; measuring a scattering signal of the electromagnetic radiation returned from the cloud over a range of a field of view angles p removing a portion of the measured scattering curve; replacing the removed portion with an extrapolation of the remaining measured scattering curve to provide an estimated scattering curve; determining a first estimate droplet size distribution n providing a calculated scattering curve from n comparing the calculated scattering curve with the measured scattering curve to determine whether the calculated scattering curve follows the measured scattering curve within a set tolerance; determining a first estimate of a droplet median volume diameter (D altering the value of D
