Chinese scientists recently carried out the "Jimu-1" tethered balloon atmospheric observation experiment in Lulang, Nyingchi, southwest China's Xizang Autonomous Region, which is expected to provide a new perspective for unraveling the mysteries of the Qinghai-Tibet Plateau ecosystem.
The tethered balloon was equipped with 16 types of scientific payloads with a total weight of approximately 200 kilograms. It successfully ascended to an altitude of 5,500 meters. Through coordinated multi-payload observations, the experiment achieved a technological leap from single-point sampling to three-dimensional monitoring, according to the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences, the major developer of the tethered balloon.

A research team led by Prof. WU Qingbai from the Northwest Institute of Eco-Environment and Resources of the Chinese Academy of Sciences has identified important non-temperature environmental factors contributing to permafrost degradation on the Qinghai-Tibet Plateau.
Chinese and international researchers have been continuing with their second scientific expedition to the Qinghai-Xizang Plateau over the past eight years, with part of their efforts focused on the study of glacier ice cores that hold significant clues about the Earth's climatic and environmental shifts.
