Abstract: The ozone valley over the Tibetan Plateau has a significant impact on global climate. To explore the specific temporal and spatial characteristics of the ozone valley, this study primarily utilizes daily total ozone columns, monthly average tropospheric ozone columns, and ozone profiles derived from OMI and MLS over the Tibetan Plateau from 2010 to 2023. The study analyzes the spatial and temporal distribution characteristics of the ozone low-value center over the Tibetan Plateau and briefly discusses the possible causes of this phenomenon. The results indicate that: (1) Compared to other regions at the same latitude globally, the Tibetan Plateau exhibits a distinct low-ozone phenomenon during the summer; (2) Vertically, the low ozone values over the Tibetan Plateau are mainly concentrated within the 15-20 km range, with the lowest value corresponding to an altitude of 16.8 km, roughly at the tropopause; (3) There are significant regional differences in the low-ozone phenomenon within the Tibetan Plateau, with opposite patterns observed between the southern and northern parts during the winter.
