CPS sonde (MR18-05C)

To understand the vertical profiles of Arctic clouds, we conducted Cloud Particle Sensor (CPS) sonde observations over the Arctic Ocean and Bering Sea. The CPS sonde, which is developed by Japanese Meisei Electric Co., Ltd. (Meisei), measures vertical distributions of cloud particles (number of density, size and the phase (water cloud or ice cloud)) in addition to the meteorological elements (Temperature, Relative Humidity, Height, Wind direction and Wind speed). This is a first trial of cloud particles observation over the Arctic Ocean on R/V Mirai.
