Global port environmental data used for environmental distance calculations

This dataset contains a list of 8392 global commerical shipping ports, with geographic coordinates and four environmental variables (i.e. salinity, mean temperature during the warmest month, mean temperature during the coldest month and annual average temperature (all at water surface)). Data were primarily sourced from the U.S. National Oceanic and Atmospheric Administration World Ocean Atlas. Data for estuarine and riverine ports has been corrected, where better information was available, with particular focus on Canadian port data and top last-ports-of-call for ships arriving to Canada.

本数据集包含8392个全球商业货运港口的相关信息，涵盖各港口的地理坐标与四项环境变量，即盐度（salinity）、暖季平均水温、寒季平均水温及年平均水温，所有数据均取自水体表层。本数据集的数据主要来源于美国国家海洋和大气管理局（U.S. National Oceanic and Atmospheric Administration）世界海洋图集（World Ocean Atlas）。针对河口港与内河港的相关数据，在可获取更优质信息的前提下已完成校正，其中重点针对加拿大港口数据以及驶往加拿大船舶的主要最终挂靠港口数据进行了优化处理。
