One of these was provided by NOAA (National Oceanic and Atmospheric Administration, USA) and was located by the cloud-radar container, on the roof of the Icebreaker Oden's foredeck lab. This system additionally recorded the backscatter profile, and hence serves as a \u201cpoor-man's lidar\u201d. When the attenuation of the laser beam reaches a threshold, like in a dense fog, it switches to reporting \u201cvertical visibility\u201d, rather than cloud-base height.","url":"http:\/\/bolin.su.se\/data\/oden-ascos-2008-ceilometer-1","keywords":["Atmosphere","Clouds","ASCOS","Meteorology","High Arctic","Arctic boundary layer","Arctic clouds","Cloud-base heights","Cloud fractions","Earth science > Atmosphere"],"creator":{"@type":"Person","name":"Matthew Shupe"},"citation":"Tjernstr\u00f6m, M. et al. 2014.
