Laurent Li presents a model which enables to better understand the Earth's radiation budget and the greenhouse effect mechanism.

What is the incident energy ? How is this energy modified by crossing the atmosphere ? What is the emitted energy ? Why do we use the term greenhouse effect ? And if we change the amount of

How do atmospheric pollutants impact on the climate? What is the radiative impact of aerosols? Budget of the radiative impacts. What is the benefit to the climate of improving air quality? What

Projections of future climate change rely on global climate models. Such models simulate the dynamics and physics of the coupled atmosphere-ocean system and move towards models of the full Earth
