C-band Weather Radar (MR16-06)

Low level clouds over the Arctic Ocean which usually dominate during summer have a key role for sea/ice surface heat budget. In addition, cyclones which modify the sea-ice distributions are substantially important to understand the air-ice-sea interaction. To capture the broad cloud-precipitation systems and their temporal and spatial evolution over the Arctic Ocean, three-dimensional radar echo structure and wind fields of rain/snow clouds was obtained by C-band Doppler radar observation. At the same time, scans are performed to evaluate the performance of the radar, and to develop the better strategy of the radar observation.

北冰洋上空通常在夏季占据主导地位的低层云，对海/冰表面热量收支具有关键作用。此外，能够改变海冰分布的气旋，对于理解气-冰-海相互作用而言至关重要。为捕捉北冰洋上空大范围的云-降水系统及其时空演变特征，本研究通过C波段多普勒雷达（C-band Doppler radar）观测，获取了雨雪云的三维雷达回波结构与风场数据。与此同时，本次观测还开展了雷达扫描作业，以评估雷达性能并制定更优的雷达观测策略。
