An inversion method for estimating strong point carbon dioxide emissions using a differential absorption Lidar

, 2020
Anthropogenic carbon emissions increase the atmospheric concentration of carbon dioxide, resulting in global warming and climate change. To complement the existing carbon emission verification system, it is crucial to develop a novel measurement-based ...

Measurement of CO2 rectifier effect during summer and winter using ground-based differential absorption LiDAR

, 2020
The rectifier effect refers to the exchange of CO2 near the boundary layer of the atmosphere. This effect is an important part of the carbon cycle because it affects the vertical distribution of CO2 and indirectly affects global CO2 distribution. However,
