In the 2023 “Summit Mission” Everest scientific research, the greenhouse gas concentration observation and carbon sink inversion team composed of the Institute of Qinghai-Tibet Plateau Research, Chinese Academy of Sciences and the Institute of Atmospheric Physics, conducted the first experiment using drones at the Everest station to collect atmospheric samples at different altitudes to verify the feasibility of using drones for atmospheric observation on the Qinghai-Tibet Plateau. provide help for accurate estimation of terrestrial carbon sinks on the Tibetan Plateau.
From May 8 to 10, Wang Yilong, a researcher at the Institute of Qinghai-Tibet Plateau Research, Chinese Academy of Sciences, led a team to collect atmospheric samples at different altitudes using a drone with an atmospheric collection device for three consecutive days at the Everest Station, which is 4,276 meters above sea level.
During the three-day experiment, the team completed 13 flights and collected 60 samples, with a maximum lift height of 820 meters. The gas samples have been sent back to the laboratory of the Tibetan Plateau Institute in Beijing for analysis of greenhouse gases and pollutants such as carbon dioxide, methane, nitrous oxide and sulfur hexafluoride.
This experiment is the first time that Everest scientific research has used a drone to collect atmospheric samples. The drone is simple and portable, making it easy for the research team to conduct atmospheric observations at more stations on the Tibetan Plateau.
The team has completed the preliminary investigation of the observation sites and plans to start the construction of the observation network from 2023, and expects to gradually complete the layout of the sites on the Tibetan Plateau and carry out continuous atmospheric observation by various means in the next few years.
