Within the UTLS, complex connections between chemistry, dynamics, and radiation are driven by fine vertical and horizontal scale processes that occur on short timescales, yet have lasting and widespread influence. These processes include convection in severe storms, high cloud formation, atmospheric waves, and emissions from large fires and volcanic eruptions, which influence the ozone layer, climate, extreme weather events, and air quality. <\/p>\n<p style=\"font-style:normal;font-weight:300\">Accurately representing these complex processes in global Earth system models presents significant challenges, resulting in forecast uncertainties. <strong>While current satellite limb sounders have advanced in our understanding of large-scale UTLS variability, their coarse vertical resolution (3-5 km) and limited sampling hinder detection of finer scales critical to capture stratosphere-troposphere interactions.<\/strong>&nbsp;<\/p>\n<div class=\"wp-block-columns is-layout-flex
