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
