1993-2020年全球海洋0.25度有效波高逐日数据

海浪是发生在海洋中的一种波动现象，作为海洋动力学过程中最基本也是最重要的环境参数，海浪在上层海洋过程和海气界面能量交换中起到了关键作用。有效波高是描述海浪特征的主要参数之一，在海洋研究和海洋环境预报中具有重要作用。某一时段连续测得的所有波高按大小排列，取总个数中的1/3个大波波高的平均值，称为有效波高。
对有效波高多源遥感数据进行了预处理和质量控制，基于反距离加权插值方法，利用T/P、Jason-1、Jason-2、Jason-3、ENVISAT RA-2、Cryosat-2、ERS-1、ERS-2、GFO、HY-2、SARAL和Sentinel-3等卫星高度计数据和ENVISAT ASAR海浪谱数据，生成了1993-2020年的全球海洋0.25°分辨率每日有效波高产品。

Waves are a type of oscillatory phenomenon occurring in oceans. As the most fundamental and critical environmental parameter in ocean dynamic processes, waves play a pivotal role in upper ocean processes and air-sea interface energy exchange.

Significant Wave Height (SWH) is one of the primary parameters characterizing wave features, and it plays a vital role in oceanographic research and marine environmental forecasting. The significant wave height is defined as the average value of the largest one-third of all wave heights measured consecutively over a certain period, after sorting all measured wave heights by their magnitudes.

Multi-source remote sensing data of significant wave height were preprocessed and subjected to quality control. Based on the Inverse Distance Weighted (IDW) interpolation method, using satellite altimeter data from missions including T/P, Jason-1, Jason-2, Jason-3, ENVISAT RA-2, Cryosat-2, ERS-1, ERS-2, GFO, HY-2, SARAL and Sentinel-3, as well as ENVISAT ASAR wave spectrum data, a daily significant wave height product with 0.25° spatial resolution for global oceans from 1993 to 2020 was generated.
