Title and thesis summary
Aerosol spatial and temporal variability as seen by Mobile Aerosol Monitoring System (MAMS)
Aerosols are a variable component of the atmosphere, having an important and complex role on air quality and climate. Most of the ground-based aerosol observations are limited to fixed locations, narrowing the knowledge on their spatial variability. In order to overcome this issue, a compact Mobile Aerosol Monitoring System (MAMS) has been developed to explore the vertical and spatial variability of aerosol optical and microphysical properties. MAMS is a vehicle-based laboratory, distinguished by other transportable platforms through its ability to perform measurements during the movement. Equipped with remote sensing and in situ instruments, MAMS explored the aerosol variability through mobile on-road campaigns in various situations. This work presents variability studies and remarkable events observed both in France and in China. One of the researched aerosol variables is their mass concentration and vertical distribution. This challenge is taken up in this work.
The mobile system presents a great flexibility and is cost-effective, being able to respond quickly in case of sudden aerosol events such as pollution episodes, dust, fire or volcano outbreaks, proving to be a useful platform for aerosol observation and operational networks. Applications of the mobile exploratory platform for validation activities of space missions observing the Earth and the atmosphere, for models’ evaluation and for instrument intercomparison campaigns are presented. New perspectives, both on instrumental and methodology levels are introduced, leaving place for improvements in the mobile aerosol observations.
Keywords: aerosols, variability, mobile measurements, air quality, remote sensing, concentration profiles.
