| Data Summary | This is the ship-borne ceilometer data over the northwestern Pacific and the Indian Southern Ocean, and at Syowa Station, Antarctica. The observations were made during ten annual cruises of the icebreaker Shirase for the Japanese Antarctic Research Expedition (JARE) from November to April. The first cruise for the observation departed Tokyo, Japan in November 2010. Since then, the observations have been carried out every year, and the final observation cruise departed in November 2019. The ceilometer emits light vertically upward and measures the intensity of backscattered light from the atmosphere. The records include the vertical profiles of the backscatter intensity, analyzed cloud base heights for each profile, and observational condition such as the time, the location, etc. Our observation is mainly for the Southern Ocean and the Antarctic region, but also includes observation data over the North Pacific Ocean south of Japan. |
