EPITOME ship emissions: Projections of shipping emissions towards 2050.

As part of the EPITOME project, we have setup global shipping emission scenarios. They are based on a combination of the global CO2 ship emission inventory for 2015 produced with the Ship Traffic Emissions Assessment Model (STEAM) (Johansson et al., 2017) and Arctic fuel consumption and emission scenarios calculated with the DCE ship emission model (Winther et al., 2017). The scenarios include a Baseline scenario, a SOx Emission Control Area (SECA) and a heavy fuel oil (HFO) ban scenario. The Baseline scenario is calculated in two variants involving Business As Usual (BAU) and High Growth (HiG) traffic growths. The SECA and HFO ban scenarios are given with the BAU traffic development. Additionally a Polar route scenario is included, with new (diversion) ship traffic routes in the future Arctic with less sea ice. The applied traffic growths and the polar routes are Corbett et al. (2010). The emissions are monthly on a spatial resolution of 0.1º×0.1º. Base year is 2015 and the scenarios are for 2050. A scientific paper providing details on the methodology behind these data will be submitted to ACPD (Geels et al, submitted). In this paper we apply the data to assess the contribution from shipping emissions to air pollution in the Nordic and Arctic area and the potential benefits of the mitigation options included in the shipping emission scenarios. This paper should be referenced if the data is used. The data are given as netcdf files for a number of components. The emission related to the diversion routes is given as a separate field and can be added the other field.

作为EPITOME项目的组成部分，我们搭建了全球航运排放情景数据集。本数据集基于两项核心数据源的融合：其一为借助船舶交通排放评估模型（Ship Traffic Emissions Assessment Model, STEAM）生成的2015年全球船舶CO₂排放清单（Johansson等，2017）；其二为利用DCE船舶排放模型计算得到的北极燃料消耗与排放情景（Winther等，2017）。本次情景涵盖基准情景、硫氧化物排放控制区（SOx Emission Control Area, SECA）情景以及重质燃料油（heavy fuel oil, HFO）禁运情景。基准情景包含两种演变变体，分别对应常规发展（Business As Usual, BAU）与高速增长（High Growth, HiG）两类航运交通增长模式；SECA情景与HFO禁运情景均基于BAU航运交通发展路径设定。此外，本数据集还包含极地航线情景，即未来北极海冰缩减背景下新增的（改道）船舶交通航线场景。本次研究所采用的交通增长参数与极地航线方案，参考自Corbett等（2010）的研究成果。排放数据采用月度尺度，空间分辨率为0.1°×0.1°。数据集基准年为2015年，情景模拟时段为2050年。详细阐述本数据集构建方法的学术论文已投稿至《Atmospheric Chemistry and Physics Discussions》（ACPD，Geels等，待刊），该论文将利用本数据集评估航运排放对北欧与北极地区大气污染的贡献，以及航运排放情景中纳入的各类减排方案的潜在效益。若使用本数据集，请引用该篇学术论文。本数据集以NetCDF格式文件存储，涵盖多种排放组分。与改道航线相关的排放数据单独作为一个数据字段存储，可与其他数据字段进行叠加计算。

背景概述

该数据集是EPITOME项目的一部分，提供了全球航运排放的预测情景，包括基线、SOx排放控制区（SECA）和重燃油（HFO）禁令等多种情景，预测至2050年。数据基于2015年全球CO2航运排放清单和北极燃料消耗模型，具有0.1º×0.1º的空间分辨率和月度时间尺度，以netcdf格式提供多种排放成分（如CO2、NOx、SO2等），适用于评估航运排放对空气污染和健康的影响。
