China News Service, Xi’an, November 4 (Yang Yingqi and Zhang Yichen) A reporter learned from the Xi’an Branch of the Fifth Academy of Aerospace Science and Technology Group (hereinafter referred to as Xi’an Branch) on the 3rd that recently, the Xi’an Branch and its brothers formed a scientific expedition team to develop a new system on the Qinghai-Tibet Plateau. Research on the hydrological cycle mechanism and change trend of radiometer observation.

It is reported that this scientific expedition laid the foundation for the verification of detection mechanism and detection equipment.

  It is understood that due to climate warming, the cryosphere of the Earth's three poles (Antarctica, Arctic and Qinghai-Tibet Plateau) has undergone great changes, including glacier degradation, reduction of snow cover, and acceleration of frozen soil degradation.

The changes in the three-pole environment have an important impact on the local ecosystem and human activities such as climate research, the opening of waterways, and resource extraction.

In order to study the hydrological cycle mechanism and change trend of the Qinghai-Tibet Plateau, the scientific expedition team of the Xi'an Branch went to the Dongkemadi Glacier in the Tanggula Pass to carry out glacier, snow, frozen soil, and hydrological observation activities.

  On the day of the test, the scientific expedition team members of the Xi'an Branch drove through the rocky area and walked for more than half an hour before reaching the test site at an altitude of 5,300 meters, and began the ice-piercing radiometer test.

While overcoming the physical test, the team members set up a test platform, operated the equipment smoothly, successfully collected test data, and obtained correct test results.

  The Xi’an Branch said that the Dongkemadi Glacier scientific expedition verified the measurement mechanism and inversion method of the broadband microwave radiometer.

The new radiometer of the Xi'an Branch provides surface and subsurface ice and snow information, and combined with other existing methods, it can more comprehensively measure the three-dimensional structure of the polar region.

  The scientific expedition team members of the Xi'an Branch said that in this experiment, everyone upholds a scientific, realistic and serious work attitude, and through unity and cooperation to overcome difficulties to complete the task, they have demonstrated the aerospace spirit.

  It is reported that the use of a new radiometer to observe glaciers by the Xi’an Branch will lay the foundation for subsequent studies on the Earth’s tripoles.
