Ground-based vertical profile observations of atmospheric composition on the Tibetan Plateau (2017–2019)

Abstract. The Tibetan Plateau (TP) plays an essential role in modulating regional and global climate, its influence on climate is also affected by human-related processes, including changes atmospheric composition. However, observations of composition, especially vertical profile observations, remain sparse rare the TP, due to extremely high altitude, topographical heterogeneity grinding environment. Accordingly, forcing feedback composition from rapidly changing surrounding regions environmental change TP remains poorly understood. This paper introduces a high-time-resolution (∼15 min) observational dataset (aerosols, NO2, HCHO HONO) for more than 1 year (2017–2019) using passive remote sensing technique. diurnal pattern, distribution seasonal variations these pollutants are documented here detail. sharing this would benefit scientific community exploring source–receptor relationships climate.
