Sermilik Trough Atlantic Water intrusion events (2010-2013)

Observations of 58 Atlantic Water intrusion events along Sermilik Trough, Southeast Greenland from 2010-2013. The intrusions were manually identified using Moderate Resolution Imaging Spectroradiometer (MODIS) visible (MOD09 - MODIS/Terra Atmospherically Corrected Surface Reflectance 5-Min L2 Swath 250m, MYD09 - MODIS/Aqua Atmospherically Corrected Surface Reflectance 5-Min L2 Swath 250m) and thermal (MODIS_A-JPL-L2P-v2014.0, MODIS_T-JPL-L2P-v2014.0) imagery and were identified to be caused by coastal trapped waves interacting with continental shelf bathymetry and often were associated with upwelling-favorable alongshore winds along the coastline. Dates for those sightings were recorded in this dataset along with the timing of the transition from downwelling to upwelling-favorable winds (initiating the intrusions) recorded from ERA-5 reanalysis 10 m wind stress. We include other information about the intrusions as well.

本数据集收录了2010-2013年沿格陵兰东南部塞尔米利克海槽（Sermilik Trough）发生的58次大西洋水入侵事件观测记录。此次入侵事件通过中分辨率成像光谱仪（Moderate Resolution Imaging Spectroradiometer, MODIS）的可见光影像（MOD09：MODIS/Terra大气校正地表反射率5分钟L2条带250米产品；MYD09：MODIS/Aqua大气校正地表反射率5分钟L2条带250米产品）与热红外影像（MODIS_A-JPL-L2P-v2014.0、MODIS_T-JPL-L2P-v2014.0）手动解译识别。经分析，此类入侵由沿岸捕获波与大陆架地形相互作用引发，且常与沿海岸线的有利于上升流的沿岸风场相关联。本数据集同时记录了各入侵事件的发生日期，以及由ERA-5再分析10米风应力数据提取得到的、触发此类入侵的风场转换时刻——即从下降风转为有利于上升流的风场的时间，此外还收录了与该类入侵事件相关的其他补充信息。
