Comparisons with in situ, surface remote sensing, aircraft, and balloon and satellite observations show that the new CAMS system is a significant improvement. The results quantify the skill of CAMS to forecast impactful events, such as wildfires, dust storms and air pollution peaks. </div> <div><a href="#" class="show-hide triangle" data-hide=".short_summary_117246" data-show=".short_summary_button_117246">Hide</a></div> </div> </div> </div> <div class="grid-15 tablet-grid-15 text-right hide-on-mobile"> <a class="paperlist-avatar" target="_blank" href="https://acp.copernicus.org/articles/24/9475/2024/acp-24-9475-2024-avatar-web.png"> <img class="img-responsive" src="https://acp.copernicus.org/articles/24/9475/2024/acp-24-9475-2024-avatar-thumb80.png" data-web="https://acp.copernicus.org/articles/24/9475/2024/acp-24-9475-2024-avatar-web.png" data-width="600" data-caption="© Author(s).
