Statistical measurement of atmospheric 6328-A attenuation using a sequential laser transmissometer.
A recording transmissometer for the statistical measurements of atmospheric attenuation at 6328 A has been set up. It measures attenuations greater than 1 dB/km, on a 90-m folded back path. The stability of its operation makes it useful in automatic continuous measurements. The instrument and the way in which the measurements are made are described, and typical results are presented.
