海洋二号卫星(HY-2)是中国第一颗海洋动力环境监测卫星,如何有效地利用海洋二号卫星扫描辐射计数据监测海冰成为亟待解决的问题。根据海冰与海水辐射特征,提出一种基于多频段双极化反演海冰密集度方法,该方法利用简化的辐射传输模型和地物参考点模拟亮温并逼近观测亮温。该方法与NASA Team 2和ABA算法具有很好的可比性。应用该方法,可以有效利用HY-2卫星反演海冰密集度,监测海冰边缘与面积变化。 |

Sea ice is a crucial component of global climate system,which is an effective index of global climate change.HY-2(HaiYang-2)satellite is the first satellite of China particularly used for monitoring Ocean environmental dynamics.With the launch of HY-2,valuable oceanic data are obtained day and night, regardless of could cover.Thus,how to use HY-2satellite to monitor polar sea ice is needs to be solved urgently. A new sea ice concentration retrieval algorithm is advanced based on radiative characteristics of water and sea ice.The new algorithm is comparable to NT2algorithm and ABA.With this algorithm,sea ice concentration could be retrieved successfully using HY-2passive microwave data. |
