Data accompanying the research on Seasonal modulation of Arctic M2 tide

The dataset constists of two files with data obtained in a study on the influence of Arctic fast ice on the seasonal modulation of the m2 tide. The first dataset contains (mean/March/September) M2 amplitude and phases and the magnitude of their seasonal modulation as computed from SAR altimetry-derived water levels. The second one contains March and September M2 amplitudes and phases as derived from a model (GTSM; fine grid) that is forced by a seasonally varying fast ice cover. The latter was done for 2013 and 2017, years with respectively the maximum and minimum fast ice cover within the time span of the considered SAR data.

本数据集包含两份文件，其数据源自一项针对北极固定冰对M2潮汐（M2 tide）季节调制影响的研究。第一份文件包含（平均值/3月/9月）的M2潮汐振幅、相位，以及由合成孔径雷达（SAR，Synthetic Aperture Radar）测高水位数据计算得到的其季节调制幅度。第二份文件则包含由受季节变化固定冰覆盖驱动的模型（GTSM；精细网格）反演得到的3月与9月M2潮汐振幅与相位。该数据集的第二部分对应2013年与2017年，这两个年份分别为所纳入SAR数据时间跨度内北极固定冰覆盖量达到最大值与最小值的年份。
