ABSTRACT:
A present weather observing system including a radiation source for providing a beam of radiation in the atmosphere and a detector for detecting scattered radiation from suspended or precipitating particles within a sample volume, the detector having a field of view intersecting the beam to define the sample volume. The invention further includes a device for determining the size and velocity of at least one particle precipitating through the sample volume, and an element responsive to the device for determining size and velocity for identifying the type of precipitation.
