Abstract:
We first review the current practices for airborne pollen and spores monitoring based on volumetric sampling and manual microscope counting. We then discuss the advantages of an automated system producing real-time data and possible applications.
Different prototypes for automatic pollen monitoring were tested at the Federal Office of Meteorology and Climatology in Payerne. Those systems are based either on image recognition or on air-flow cytometry. While all systems were able to show good correlation with manual counts regarding total pollen count, the identification of different taxa appears to be more challenging. We focus on the system currently in validation phase at MeteoSwiss (PA-300, Plair, Switzerland), expected to demonstrate the capability of detecting and counting different types of particles, including some air pollutants and several pollen types. We present results of pollen identification tests and a first comparison between manual and automatic counts for the 2015 campaign.
Short biography:
Benoît Crouzy studied physics at EPFL and ETHZ. After a PhD in theoretical physics (2009) he moved to hydrology and spent four years as a postdoc in the group of professor Paolo Perona (EPFL). Currently he is working as a scientist at MeteoSwiss in the group of biometeorology (group leader Dr. Bernard Clot).
He is mainly interested in mathematical methods applied to environmental sciences.
