TWO HEADS ARE BETTER THAN ONE: ADVANTAGES OF THE BIRAL BACK SCATTER HEAD FOR PRECIPITATION CLASSIFICATION

摘要

Infrared light emitted by the transmitter that is scattered by 39-51° is detected by the forward scatter receiver. This is sufficient to estimate the visibility and aid the classification of precipitation type. The infrared light which is scattered by 107-119° is detected by Biral's unique back scatter receiver, which is used in addition to the forward scatter measurement to heip discriminate between different types of precipitation, such as rain and snow. A diagram of the scattering angles in relation to a Biral visibility and present weather sensor is shown in Figure 1.
