Sea Ice Motion in the Arctic Ocean Switchyard

This dataset provides sea ice motion vectors in the Switchyard region of the Arctic Ocean, utilizing measurements from the 89V channel of the AMSR-E instrument on the Aqua platform. The daily fields cover the period of October 1, 2002 through December 31, 2008. They are on a 100km resolution grid in Special Sensor Microwave Imager (SSMI) x/y coordinates, from the North Pole down to the Canadian Archipelago and Greenland coasts, between 0 degrees longitude and 120 degrees west longitude. These ice motion vectors provide measurements of ice circulation and flux in the switchyard region, showing the balance of the sea ice flow going into the Fram Strait and exiting the Arctic Ocean and that flowing toward the Beaufort Sea and remaining within the Arctic system.

本数据集提供北冰洋海冰开关区（Switchyard region）的海冰运动矢量（sea ice motion vectors），数据基于Aqua卫星平台上搭载的AMSR-E仪器的89V通道观测结果。该每日格场数据的时间跨度为2002年10月1日至2008年12月31日，采用100公里分辨率的格网，坐标系为专用微波成像仪（Special Sensor Microwave Imager，SSMI）x/y坐标系，覆盖范围北起北极点，向南延伸至加拿大北极群岛与格陵兰岛沿岸，经度区间为0°至120°西经。此类海冰运动矢量可用于量化该开关区内的海冰环流与通量，能够反映流入弗拉姆海峡并脱离北冰洋的海冰，与流向波弗特海并留存于北极系统内的海冰之间的平衡关系。
