Scientists develop new land surface model to monitor global river water environment

Climate change and human activities, including heat emission, nitrogen (N) emission and water management, are altering the hydrothermal condition and N transport in the soil and river systems, thereby affecting the global nitrogen cycle and water environment.


“We need to assess the impacts of these human activities on global river temperature and riverine N transport,” said Prof. Xie Zhenghui from the Institute of Atmospheric Physics of the Chinese Academy of Sciences. “Quantitative assessment can not only improve our understanding of the material and energy cycle that occur in response to anthropogenic disturbances, but also contribute to protecting river ecosystems.”

Xie and his collaborators from the Chinese Academy of Sciences incorporated the schemes of riverine dissolved inorganic nitrogen (DIN) transport, river water temperature, and human activity into a land surface model, and thus developed a land surface model CAS-LSM. They applied the model to explore the impacts

Tesla Model 3’s driver-facing camera ‘does more than just monitor passengers’

A hacker has revealed the key events that the Model 3’s driver-facing camera is designed to detect – and it appears to do much more than Tesla CEO Elon Musk has so far admitted.

Musk in April confirmed that one use of the driving-facing camera, which is located in the center of the rear-view mirror of all Model 3s, would be used for monitoring passengers in its future network of robotaxis. The camera could be used to dissuade passengers from vandalizing vehicles or at least capture evidence of such acts. 

At that stage the camera had been inactive in all Model 3s, but in June, some three years after the model first hit the road, Tesla issued a software update that activated the camera. 

As Electrek reported at the time, Tesla allowed some Model 3 drivers to enable the camera, which allowed Tesla to “automatically capture images and a short
