Abstract:

An evaluation of three scattering-type visibility instruments has been made under wide ranging weather conditions at a test site near Hanscom AFB, Mass. The sensors tested were the EG and G Forward Scatter Meter FSM, the Impulsphysik Videograph, and the MRI Fog Visiometer. Data were gathered during periods of fog, rain, and snow in order to calibrate the Videograph and Fog Visiometer to the extinction coefficient output of the FSM and to develop correlation and error of estimation statistics between the outputs of the three sensors. Consideration was given to the suitability of the instruments for use in remote and fully automated weather observation systems.
