Data underlying the paper: North-Sea infragravity wave observations

10 minute observations of short and long waves on the North Sea at stations A12, Q1 and EUR. A12 and Q1 from 2009-2018 and EUR from 2010-2019. Data have been split in two directories: short_waves for the spectral sea-swell conditions and long_waves for the long wave surface elevation time series. Data have been collected by Rijkswaterstaat and used in the manuscript by Reniers et al., 2020, North-Sea Infragravity wave observations, JMSE, in prep.<br>

针对北海A12、Q1及EUR三个测站的短波与长波开展了10分钟时长的观测。其中A12与Q1测站的观测时段为2009年至2018年，EUR测站的观测时段为2010年至2019年。数据集已分为两个子目录：`short_waves`目录存储频谱海涌条件相关数据，`long_waves`目录存储长波海面高程时间序列数据。本数据集由荷兰国家水利管理局（Rijkswaterstaat）采集，已应用于Reniers等人2020年提交至《海洋科学与工程学报》（JMSE）的待刊手稿《北海次重力波观测》中。
