  "abstract": "Atmospheric O₃ possesses a rare isotopic signal, that is, Δ¹⁷O(O₃), varying with pressure and temperature, providing a potential tracer to explore stratosphere‐to‐troposphere transport (STT) of O₃ that plays a vital role in atmospheric chemistry and climate. However, it has been proposed that the higher stratospheric Δ¹⁷O(O₃) can't be preserved en‐route to the troposphere given the rapidly re‐established isotopic equilibrium by photochemistry. Here, we reported Δ¹⁷O(O₃) data mainly from the Tibetan Plateau, and found the relatively high Δ¹⁷O(O3) at Mt. Everest can't be explained by in situ photochemistry. Instead, the distinct diurnal cycle with elevated nighttime value at Mt. Everest is associated with the katabatic wind bringing stratosphere‐sourced O₃ with high Δ¹⁷O. This demonstrates that the high Δ¹⁷O(O₃) can be preserved at troposphere at some circumstances. Given the fast transfer of Δ¹⁷O(O₃) to atmospheric nitrate, it might be potential to probe past STT of O₃ using nearby ice core records of nitrate.",
