Beijing Science and Technology Association and Beijing Radio and Television Station jointly created a large-scale scientist interview program "Science Collection Living Room", inviting experts and scholars from the current cutting-edge popular science and technology fields to tell the wonderful moments and moving moments in the scientific research process.
Tonight, go to the Beijing Science and Education Channel to see the story of Zhao Yiming doing CT to the atmosphere by the Laser Research Office of the 704th Institute of the Ninth Academy of China Aerospace Science and Technology Corporation.
August 4, 2022
my country successfully launched the "Jumang" satellite
This is my country's first terrestrial ecosystem carbon monitoring satellite
It can accurately measure the
carbon dioxide and other pollutants in the atmosphere from space
3D data of carbon dioxide and other pollutants
is like doing CT for the atmosphere
This satellite is so powerful
is because it is equipped with high-precision
ml1 lidar
and this cannot be separated from Zhao Yiming's more than ten years of exploration and research
student
Zhao Yiming studied in the field of lidar
When he was studying abroad
When she was a student
When she was studying abroad
she personally felt the advanced European lidar
When she attended an academic conference
she witnessed foreign scientists attribute domestic pollution causes
to China
but China could not provide relevant lidar data
to prove it It shows the facts
This made her determined to return to China
develop China's own lidar
When she returned to China
had many difficulties
because the domestic related talents lacked
and the lidar performance was very different from that of foreign countries
In such an environment
formed a team bit by bit
overcome difficulties
successively developed ground-based multi-beam lidar
and satellite-borne multi-beam lidar
allows China to have its own lidar
Zhao Yiming said that
is equipped with satellite-borne multi-beam lidar
"Jumang" satellite
monitors carbon reserves
checks ecological resources in detail
monitoring national major ecological engineering monitoring and evaluation and other directions
can provide remote sensing monitoring services
contribute to the construction of beautiful China
want to know how Zhao Yiming
walks through this difficult scientific research path?
