5203 |a"The Videograph visibility sensor has been calibrated against the prevailing visibility observations of meteorological observers in a variety oftemperate climate conditions by the Atmospheric Environment Service in 1970-1. Because this instrument is soon to be used at Canada's Meteorological Automated Reporting Stations in Arctic locations, we required additional calibration information for visibility restrictions experienced in colder climates. A Videograph was installed at Yellowknife Airport for the winter of 1975-6 to relate the daytime calibration in ice fog and ice crystals to that in snow. A graphical presentation of the data indicates no significant difference in the calibration for ice fog/crystals and snow"--Abstract.
