Arctic ship traffic air pollutant emissions inventory 2013-2022

Monthly gridded ship-associated emissions (carbon monoxide (CO), sulfur oxides (SOx), nitrogen oxides (NOx), and volatile organic compounds (VOC)) in the Barents and Kara Sea region from 2013 - 2022. Data is collected from the Protection of the Arctic Marine Environment's (PAME) Arctic Ship Traffic Database (ASTD) and aggregated to monthly sums in a 0.1x0.1 longitude latitude grid. Emissions are given in total emissions (tonnes) per month (unit: tonnes/month), where the filename indicate year and month: ASTD_shipping_emissions_yyyy_mm. NB: Each file contains 12 time layers, which requires the user to refer to correct timestamp to view data (i. e. ASTD_shipping_emissions_2015_01, data is found in time=1. ASTD_shipping_emissions_2021_07, data is found in time=7).本数据集为2013年至2022年巴伦支海与喀拉海海域的月度网格化船舶相关排放数据，涵盖一氧化碳（carbon monoxide, CO）、硫氧化物（sulfur oxides, SOₓ）、氮氧化物（nitrogen oxides, NOₓ）以及挥发性有机化合物（volatile organic compounds, VOC）。数据源自北极海洋环境保护（Protection of the Arctic Marine Environment, PAME）发布的北极船舶交通数据库（Arctic Ship Traffic Database, ASTD），并被聚合至0.1×0.1经纬度网格的月度总排放量。排放数据以月度总排放量为单位，单位为吨/月（tonnes/month），文件名遵循"ASTD_shipping_emissions_yyyy_mm"的格式以标注对应年份与月份。注意：每个文件包含12个时间层，用户需通过正确的时间戳索引查看对应数据，例如："ASTD_shipping_emissions_2015_01"的数据对应时间层time=1；"ASTD_shipping_emissions_2021_07"的数据对应时间层time=7。
