Global shipping emissions for the years 2013 and 2016-2021

<p>The shipping emission datasets of the globe with 9<strong> </strong>species (NO<em>_x</em>, CO, HC, SO₂, PM_2.5, CO₂, &nbsp;&nbsp;N₂O, CH4, and BC) with a spatial resolution of 0.1^o &times; 0.1^o, the temporal resolution of days for the years 2013 and 2016-2021 were established based on SEIM (Sipping Emission Inventory Model). Based on well-cleaned AIS (Automatic Identification System) data and&nbsp; STSD (Ship Technical Specifications Database), SEIM model can simulate ship emissions for every ship by every two subsequent AIS signals, which are typically only a few seconds or tens of seconds apart. For a detailed introduction to the SEIM, please refer to our previous articles: https://www.nature.com/articles/nclimate3091, https://acp.copernicus.org/articles/21/13835/2021/</p>
