Datasets to paper "Changing Sea Level, Changing Shorelines: Integration of Remote Sensing Observations at the Terschelling Barrier Island"

This dataset contains all input and output datasets required to reproduce the figures of the accompanying paper. This research combines and compares different types of coastal remote sensing datasets in order to assess the potential of remote sensing techniques to detect a geometrical relationship between sea level rise and shoreline retreat for a case study at the Terschelling barrier island at the Northern Dutch coast. The input data comprises different types of coastal observations from secondary sources. These are shoreline positions, sea level from altimetry and from tide gauges, vertical land motion from GNSS, land elevation data (JARKUS dataset) and auxiliary datasets (e.g. mean sea level pressure, land ocean mask). The output comprises sea level (from altimetry and tide gauges) corrected for atmospheric pressure and tides, as well as the individual corrections, timeseries of cross-shore changes computed with different parameter settings, cross-shore timeseries computed as the intersection between sea level and land elevation from JARKUS and beach slopes.<br>Secondary sources comprise Altimetry data downloaded from the OpenADB database (https://openadb.dgfi.tum.de/en/)Shorelines extracted from Landsat images with CASSIE (https://cassiengine.org/)Tide gauge observations from PSMSL (https://psmsl.org)Rijkswaterstaat waterinfo (https://waterinfo.rws.nl/)GNSS processed timeseries from SONEL (https://www.sonel.org/)Mean sea level pressure from ERA5 (https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels-monthly-means?tab=overview)

本数据集涵盖复现配套论文配图所需的全部输入与输出数据集。本研究整合并对比了多类海岸遥感数据集，旨在评估遥感技术在荷兰北部海岸特塞尔屏障岛（Terschelling barrier island）案例中探测海平面上升与岸线后退之间几何关系的潜力。
输入数据包含来自二手数据源的多类海岸观测数据，具体包括岸线位置、卫星测高与验潮仪获取的海平面数据、全球导航卫星系统（GNSS）测得的垂直陆地运动数据、陆地高程数据集（JARKUS）以及平均海平面气压、陆海掩膜等辅助数据集。
输出数据包含经大气压强与潮汐校正后的海平面数据（源自卫星测高与验潮仪）、各类校正项、采用不同参数设置计算得到的岸向变化时间序列，以及通过将海平面与JARKUS数据集的陆地高程结合海滩坡度计算得到的岸向变化时间序列。
二手数据源涵盖：从OpenADB数据库（https://openadb.dgfi.tum.de/en/）下载的卫星测高数据；通过CASSIE工具（https://cassiengine.org/）从陆地卫星（Landsat）影像中提取的岸线数据；验潮仪观测数据来自国际海平面永久服务（PSMSL，https://psmsl.org）与荷兰公共工程与水管理局（Rijkswaterstaat）的waterinfo平台（https://waterinfo.rws.nl/）；由SONEL平台（https://www.sonel.org/）处理得到的GNSS时间序列数据；平均海平面气压数据源自ERA5再分析资料（https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels-monthly-means?tab=overview）
