- Abstract
- Determining how aerosol particle number size distributions evolve during long range transport and how aerosol sources contribute to the aerosol population is one of the greatest conundrums in aerosol science. Current monitoring of particle size distribution is done in fixed stations that provide limited information about the reasons why size distribution changes with time. In this project, the Lagrangian approach was applied to measure particle size distribution in an air mass while it was being transported. This was achieved by installing a Scanning Mobility Particle Sizer (SMPS) and a collection of sensors for temperature, humidity, ozone, CO2, NO2, PM10 and PM2.5 inside a car, measuring the conditions of the air mass for 6-7 hours...

The results of this pilot project, divided into three case studies, have proven the method to be effective for the application of the Lagrangian approach in continental measurements. This study aims at becoming the beginning of a new line of research. (Less)
- Popular Abstract
- The air around us contains particles of many different sizes, which are constantly getting bigger or smaller by interacting with each other and with the gases around. The particles in the air in a certain place are currently measured in fixed stations, where they are classified by size. Since the wind moves the air away from the stations, it is very difficult to guess how the particles change or where they come from. In the aerosol-chase project, we put some instruments inside a car to measure the size of the particles and the gases that make them change in size, so we can follow the air while the wind is transporting it and see what happens in the way. We have tried this method in three campaigns, and it worked, letting us see how the... (More)

We have tried this method in three campaigns, and it worked, letting us see how the particles change, understanding why they do so and having a good idea of where they come from. This is the first time that this kind of measurements is taken following the air in this way, so we hope this is the beginning of many car-chase projects. (Less)
