In ReACT we are using active and passive remote sensing to investigate atmospheric processes of importance to climate research, weather forecast, aviation and air quality.

Our experimental and theoretical work is dedicated to studies of aerosols, clouds, water vapour and their interactions using measurements from our ground-based long-term stations (Athens, PANGEA-Antikythera, Finokalia), dedicated experimental campaigns, and long-lived space borne sensors.

Key topics of our research are:

• The investigation of the processes that determine the life cycle of dust and its interactions with clouds and radiation.
• The development of new lidar instruments for dedicated studies (e.g. new polarimetric observations, evaluation of space borne lidar missions).
• The investigation of key atmospheric parameters (e.g. optical and physical properties of aerosols, clouds, water vapor, temperature, wind) above the Mediterranean.
• The 24/7 monitoring of the atmosphere, from the ground up to the stratosphere, supporting governmental and European infrastructures regulating aviation and air quality hazards (e.g. volcano eruptions, fires)."
