Atmospheric fluxes of biotic particles: measurements and models - Yves BRUNET

Many biotic particles such as pollen grains, bacteria, spores and viruses are transported by atmospheric motions.  They play important roles in various areas: the spread of biodiversity, agricultural production, plant and human pathology, biogeochemical cycles, etc. After a presentation of the main characteristics of these bioaerosols we describe the emission, transport and deposition processes to which they are submitted during their lifetime. Doing this, we provide an overview of the measurement techniques used to quantify their atmospheric concentrations and fluxes. We also describe models allowing particle transport to be simulated across a range of scales. We finally show how integrated modelling approaches can help provide guidelines for various environmental issues such as the coexistence of conventional and genetically modified crops, or the safety of industrial composting platforms.
