Abstract:

The Forward Scattering Meter FSM is a compact and ruggedized instrument developed to give estimates of the far-infrared extinction coefficient of maritime hazes and fogs. This device, developed in response to an operational requirement of the Shipboard Meteorological and Oceanographic Observation System SMOOS, utilizes the light scattered out of a HeNe laser beams into the near forward direction to scale directly to the infrared extinction. The design and operation of the FSM are described in detail. The FSM was tested in the Calspan Corporation environmental test chamber. It was subjected to various aerosol size distributions and concentrations. Data obtained show the the FSM met its design specifications. Keywords Extinction Infrared Forward scattered light Maritime hazes Fogs.
