High temporal and spatial resolution emission inventory for maritime shipping emissions on the North Sea and Baltic Sea (2015)

A temporally and spatially highly resolved emission inventory for the North Sea and Baltic Sea for the year 2015, created with current emission factors and ship activity data. The emissions inventory is available as 396 csv files, one for each day in 2015 and December 2014, grouped as monthly archives. Note that due to the underlying ship activity data and the geographic boundaries, the time index in the Datetime column in the ship_emissions_YYYYMMDD.csv files is not equidistant. For example, since vessels leave the geographic area and reenter later, no data is available for the time the vessel is not within the area. The underlying model source code is available on Github, with a release of the associated version on Zenodo: [](https://doi.org/10.5281/zenodo.6951672)

本数据集为2015年北海与波罗的海海域的高时空分辨率排放清单，采用现行通用排放因子与船舶活动数据编制完成。该排放清单以396个CSV文件形式提供，涵盖2015年全年及2014年12月的每日数据，并按月度归档包进行分组存储。需注意，由于所用基础船舶活动数据与研究区域地理边界的限制，`ship_emissions_YYYYMMDD.csv`文件中Datetime列的时间索引并非等距分布。例如，当船舶驶出研究区域后再次驶入时，其不在区域内的时段将无对应数据。本数据集所用的基础模型源代码已托管至GitHub，相关版本的归档包已发布于Zenodo平台：[](https://doi.org/10.5281/zenodo.6951672)
