| 摘 要： | 利用40%阈值法对CryoSat-2卫星波形数据进行重跟踪,将波形特征参数和海冰浓度相结合,对海冰和Lead(浮冰之间的开阔水域)进行有效识别。利用沿轨前后搜索算法计算海冰干舷高,并引用AWI结果,绘制2011~2013年北冰洋多年冰区域和一年冰区域平均海冰干舷高变化趋势图。比较本文结果与AWI结果的各年同期数据,验证本文结果的可靠性。

| Abstract: | The Cryosat-2 altimetry waveform measurements on the sea ice are retracked using the 40% threshold method in the Arctic Ocean. By combing the waveform parameters and the sea ice concentrations, the sea ice and the Lead (open water between the ice floes) are identified effectively. The sea ice freeboard is determined by along-track searching and an interpolation algorithm| it is compared with the AWI results, and the variations of the mean freeboard of the first-year and the multi-year sea ice area between 2011 and 2013 in the Arctic Ocean are given. The comparison results show good correlation in the corresponding period of each year. |
