%X The high-resolution ship emission inventory is an important dataset for various disciplines such as atmospheric science, marine science, and environmental management. Here, we present the global high-resolution ship emission inventory with a resolution of 0.1 °× 0.1 ° from 2013, 2016 to 2021, generated by the state-of-the-art shipping emission inventory model (SEIMP2.2). In terms of major air pollutants and greenhouse gases, in 2021, global ships emitted 847.2 million tons of carbon dioxide, 2.3 million tons of sulfur dioxide, 16.1 million tons of nitrogen oxides, 7.912 million tons of carbon dioxide, 737.3 million tons of hydrogen compounds, 415.5 tons of primary PM2.5, 61.6 million tons of BC, 210.3 million tons of CH4, and 45.1 million tons of N2O, accounting for 3.2% of sulfur dioxide emissions; According to the Community Emissions Data System (CEDS), 14.2% and 2.3% of all anthropogenic NOx and CO2 emissions worldwide are from human sources. According to the inventory results, the composition of ship types that contribute to global ship emissions remains relatively stable. In terms of time, the daily fluctuations in global ship emissions are the smallest. In terms of space, high-resolution emission datasets reveal the contribution patterns of ship emissions from different types of vessels in different marine regions.
