Automatic meteorological station observation dataset of Chinese Qinling station in Antarctica from 2017 to 2024

As Chinese first year-round research facility in the Pacific sector of Antarctica, it occupies a strategic position for interdisciplinary polar studies. Conventional meteorological observations, serving as the cornerstone of climatological research, yield fundamental datasets essential for earth system science investigations.

This study systematically compiles and processes Qinling Station's routine meteorological records from 2017 to 2024, employing standardized quality control protocols to establish a continuous multi-year dataset encompassing air temperature, atmospheric pressure, wind speed/direction, relative humidity, and radiation. The curated dataset partially addresses observational gaps in Antarctica's coastal meteorological network and can be used for research on climate and synoptic process changes in Antarctica. In addition, in the context of the sharp reduction of Antarctic sea ice extent in recent years, this dataset can provide data support for revealing the impact of regional climate warming on sea ice melting, calibrating climate models, and analyzing the response mechanism of the Antarctic system under global climate change.
