Abstract: Meteorological factors are one of the important elements for field observation at the Chinese Ecosystem Research Network (CERN) positioning stations, which can provide basic data for the research on ecosystem and global change, and weather forecasting. Sichuan Zoige Alpine Wetland Ecosystem National Observation and Research Station (referred to as "Zoige Station") stand as the sole newly-approved domestic alpine wetland ecological station. In 2021, Zoige Station built the vertical gradient observation of meteorological elements, which is of great significance for revealing the meteorological characteristics and the ecological protection of the alpine wetlands of Zoige Plateau. We used the Zoige Station's vertical gradient automatic meteorological observation system to ensure consistency and accuracy of the data by following the standard and specifications of the Ground Meteorological Observation Specification, and eliminating invalid data according to the relevant rules of the Ecological System Atmospheric Environment Observation Specification. We then interpolated missing data to ensure data integrity. Specifically, we compiled 24 meteorological indexes totaling 8,760 entries of daily scale data of the gradient meteorological observations at Zoige Station in 2022, including atmospheric pressure, precipitation, total radiation, photosynthetic effective radiation at 2 m above ground, air temperature, relative humidity, wind speed at the heights of 2 m, 6 m, 12 m, 16 m, and 20 m above ground, as well as soil temperature at the depths of 20 cm, 40 cm, 60 cm, 100 cm, and 150 cm. This dataset can provide data support for the ecological environment protection of Zoige Plateauand, reveal the rules of atmospheric environment changing, and scientific research on the plateau.
