A number of hypotheses have been used to explain how free oxygen first accumulated in Earth’s atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. Now a new model offers ...

Chinese scientists have constructed a numerical model to simulate the Martian atmosphere and thus assist the country's plans to collect rock samples from the Red Planet. The model replicates the ...

The search for Earth 2.0 has begun in earnest. But there's a huge variety of exoplanets out there, so narrowing down the search to focus valuable telescope time on only the best candidates is critical ...

Hybrid climate modeling has emerged as an effective way to reduce the computational costs associated with cloud-resolving models while retaining their accuracy. The approach retains physics-based ...

Climate models are complex, just like the world they mirror. They simultaneously simulate the interacting, chaotic flow of Earth’s atmosphere and oceans, and they run on the world’s largest ...
