Transmissometer Effectiveness.

Abstract

By means of BARNES transmissometers light transmission in the visible range and infra-red shall be measured under very poor visibility conditions (strong haze, fog, precipitation) over a distance of 2.7 km. To ensure exact transmission even under such conditions a telemetry link has been installed between optical transmitter and receiver. This permits now reliable measurements in both windows as low as < 0,1% transmission. Simultaneously, the telemetry link is used to transmit measured data (temperature, humidity, aerosol particle spectrum, and others) to the Institute. (Author)
