Total cloud cover(2019/06-2019/09)
This parameter is the proportion of the grid frames covered by the cloud. Total cloud cover is a single-stage field of cloud computing that occurs according to different model... -
10m component of wind(2019/10-2019/10)
This parameter is the northerly component of 10m wind. It is the horizontal speed at which the air moves northward, at an altitude of ten meters above the Earth's surface, in... -
2m temperature(2019/06-2019/09)
This parameter is the air temperature 2m above the surface of land, sea or inland waters. The 2m temperature is calculated by interpolating between the lowest model level and... -

数字极地报告_第八期（曹云锋-北京林业大学）
报告内容：受“北极放大”效应影响，北极海冰正在以前所未有的速度快速融化，为北极航运业的发展带来了重要机遇，也使得北极航道的开发问题逐渐成为学界乃至社会关注的热点。但目前仍存在诸如对北极航道历史变化规律的研究仅停留在间接认识水平、气候模式预测航道未来通航潜力结论迥异且不确定性大等认识不足问题。研究综合利用多源海冰观测数据，基于国际海事组织最新发布的POL...
