摘要

摘要: 卫星雷达高度计是海浪有效波高（significant wave height，SWH）观测的重要手段之一，本文利用时空匹配方法对T/P、Jason-1、Envisat、Jason-2、Cryosat-2和HY-2A共6颗卫星雷达高度计SWH数据与NDBC（National Data Buoy Center，NDBC）浮标SWH数据进行对比验证，并对雷达高度计SWH数据进行校正。全部卫星雷达高度计SWH数据时间跨度为1992年9月25日到2015年9月1日，对比验证NDBC浮标共53个，包括7个大洋浮标。精度评价发现除T/P外，各卫星雷达高度计SWH的RMSE都在0.4~0.5 m之间，经过校正后，RMSE都有显著下降，下降程度最大为13.82%；对于大洋浮标，评价结果RMSE在0.20~0.28 m之间，结果明显优于全部NDBC浮标的精度评价结果；HY-2A卫星雷达高度计SWH在经过校正后数据质量与国外其他5颗卫星雷达高度计SWH数据质量差异较小。

Abstract: Satellite altimetry is one of the important way to monitor significant wave height, this paper uses space-time matching method comparing SWH data of radar altimeters on board six satellites that are T/P, Jason-1, Envisat, Jason-2, Cryosat-2 and HY-2A with SWH data from NDBC buoys, and calibrates SWH data from radar altimeters. All radar altimeters data are chose from September 25, 1992 to September 1, 2015 for a period of 24 a. Matching result yields 53 NDBC buoys, including 7 oceanic buoys, evaluation of accuracy indicates RMSE between 0.4 m and 0.5 m, except T/P, after calibration, RMSE has significantly decreased, a maximum decline is 13.82%; the evaluation result of RMSE in 0.20-0.28 m for oceanic buoys, the evaluation of accuracy is better than all NDBC buoys; after calibration for SWH, there is a little bias between HY-2A satellite radar altimeter data and other 5 foreign satellite radar altimeter data.
