中文摘要：HY-2B卫星海面风场及有效波高产品在北极地区的交叉验证是实现相关产品在高纬地区推广应用的重要前提,是检验我国自主海洋动力系列卫星产品质量及应用范围的重要环节。利用2018年发射的HY-2B卫星获取的风场和有效波高数据,开展了自主海洋动力卫星与国际同类卫星产品在北极地区的交叉验证分析。近两年的观测数据表明:①HY-2B卫星与MetOp-A卫星风速风向均具有高度的一致性,数据质量稳定,精度高。风速及风向相关系数分别达0.97和0.99,均方根误差分别低于1.03 m/s和12.28°。②HY-2B卫星与Jason-3卫星有效波高数据在北极地区给定时空范围内匹配对较少,但数据的一致性及精度均较高,二者相关性达0.99,均方根误差为0.28 m。③自主HY-2B卫星风场和有效波高产品与国际同类卫星产品在北极地区均具有高度的一致性,达到业务化运行的精度要求,相关产品可满足于北极等高纬地区海面风场和有效波高的推广应用。

外文摘要：The cross-verification of HY-2B sea surface wind field and significant wave height products in the Arctic region is an essential prerequisite for the promotion and applying related products in high latitudes.It’s an important link in testing the quality and application scope of China's autonomous marine dynamic series satellite products.Based on the wind field and significant wave height data obtained by HY-2B satellite launched in 2018,cross-validation analysis between the autonomous marine dynamic satellite and similar international satellite products in the Arctic region was carried out.The observation data of the past two years show that:(1)the wind speed and direction of HY-2B satellite and MetOp-A satellite have high consistency and accuracy.The correlation coefficients of wind speed and direction were 0.97 and 0.99,and the root mean square error was lower than 1.03 m/s and 12.28°.(2)The significant wave height data of HY-2B and Jason-3 in the Arctic region have fewer matching pairs within the given space-time range,but the consistency and accuracy of the data are both high.The correlation between the two satellites is 0.99 and the root mean square error is 0.28m.(3)The autonomous HY-2B satellite wind field and significant wave height products are highly consistent with the international similar satellite products in the Arctic region,meeting the accuracy requirements of operational operation.Related products can meet the promotion and application of sea surface wind field and significant wave height in high latitude regions such as the Arctic.
