Lidar measurement of aerosols and its importance in air monitoring

Whether aerosols are of natural or anthropogenic origin, it is a major societal necessity to monitor their evolution in the atmosphere, in order to prevent health risks and anticipate more accurately the evolution of the Earth's climate. Coupled with the consequences associated with greenhouse gases, the socio-economic impact of climate disruption is already being felt in our societies, which are becoming increasingly aware that major changes are on our doorstep. These changes are already associated with persistent droughts, floods, heat waves and mega forest fires.

By combining resolved measurements in the atmospheric column with modelling, a solution can be found to better predict tomorrow's environmental and climatic disasters. This solution complements the investigative resources currently deployed, such as those used by air quality organizations, and the contribution of space observation to weather and climate forecasting.
