Underwater noise from ships during 2014-2020

These data accompany the manuscript "Underwater noise emissions from ships during 2014-2020" submitted for publication in Environmental Pollution. These data consist of daily emissions of underwater noise emissions from global shipping, reported as noise energy in Joules, in three frequencies (63, 125 and 2000 Hz). The data is provided in zip compressed gridded binary netcdf3 data format using Climate &amp; Forecast conventions. <br>本数据集配套于提交至"Environmental Pollution"（《环境污染》）期刊待发表的研究手稿《2014-2020年船舶水下噪声排放》。数据集涵盖全球航运每日产生的水下噪声排放数据，以噪声能量（单位：焦耳（Joule））为统计指标，覆盖63 Hz、125 Hz及2000 Hz三个频率频段。数据以zip压缩的网格化二进制netCDF3（网络通用数据格式3）格式提供，并遵循Climate & Forecast（气候与预报）规范。
