<p>Global reactive nitrogen (<span class="inline-formula">N</span>) deposition has more than tripled since 1860 and is expected to remain high due to food production and fossil fuel consumption. Global sulfur emissions have been decreasing worldwide over the last 30 years, but many regions are still experiencing unhealthily high levels of deposition. We update the 2010 global deposition budget for reactive nitrogen and sulfur components with new regional wet deposition measurements from Asia, improving the ensemble results of 11 global chemistry transport models from the second phase of the United Nations Economic Commission for Europe's Task Force on Hemispheric Transport of Air Pollution (HTAP II). The observationally adjusted global <span class="inline-formula">N</span> deposition budget is 114.5 <span class="inline-formula">Tg N</span>, representing a minor increase of 1 % from the model-only derived values, and the adjusted global sulfur deposition budget is 88.9 <span class="inline-formula">Tg S</span>, representing a 6.5 % increase from the modeled values, using an interpolation distance of 2.5<span class="inline-formula">^∘</span>. Regionally, deposition adjustments can be up to <span class="inline-formula">∼</span> 73 % for nitrogen and 112 % for sulfur. Our study demonstrates that a global measurement–model fusion approach can improve <span class="inline-formula">N</span> and <span class="inline-formula">S</span> deposition model estimates at a regional scale, with sufficient availability of observations; however, in large parts of the world, alternative approaches need to be explored. The analysis presented here represents a step forward toward the World Meteorological Organization's goal of global fusion products for accurately mapping harmful air pollution deposition.</p>
