(2017) Ceilometer data taken in Beaufort Sea, Northwest Passage, Baffin Bay, Canadian Arctic, ArcticNet 2016. Waterloo, Canada: Canadian Cryospheric Information Network (CCIN). ArcticNet 2016, Centre for Earth Observation Science, University of Manitoba. Unpublished Data Raw backscatter data were collected from a CT25K ceilometer. A ceilometer is a device that uses a laser or other light source to determine the height of a cloud base. Ceilometers can also be used to measure the aerosol concentration within the atmosphere. Sampling took place from May to October 2016 in the Beaufort Sea, Northwest Passage, Baffin Bay (Canadian Arctic) during the cruise onboard the CCGS Amundsen icebreaker. The CT25K is designed to detect three cloud layers simultaneously up to around 18 000 ft, given suitable conditions. Besides cloud layers, it detects whether there is precipitation or other obstruction to vision. Output files were created hourly by the system and are in ASCII format. A ceilometer was used to collect information on cloud height and backscatter data, which serves to measure the aerosol concentration within the atmosphere.
