Laboratory of Physico-Chemistry of the Atmosphere (LPCA)

Research unit - UR 4493


The laboratory carries out basic and applied research, in physics and chemistry, to better understand the impact of human activities on the environment, particularly in the area of the atmosphere.
The LPCA is organized into two themes:
1- Physico-Molecular Chemistry and Instrumentation
2- Support for Environmental Transitions
