Subproject 2 proposes to study the contribution of elements of biological origin in the composition of the atmospheric aerosol, focusing on
the meteorological aspects associated to its emission, dispersion and regional and long-range transport, with particular emphasis on:
1) The study of the dynamic and physical processes of air masses, with special interest on those associated with the emergence of
extreme meteorology (temperature and precipitation) in the Iberian Peninsula, and the analysis of their effects on the dynamics of pollen,
spores, allergens and aerial microarthropods . Relevant aspects about the relationship between the physical mechanisms that make an air
mass 'extreme' and its effects, consequences and impacts on the territory due to their influence on vegetation and health (allergies,
pathologies and pests) will be addressed.
2) The mesoscale analysis using the nested WRF model of specific episodes of relevance for their associated levels of aerobiological
particles, which will provide information at high resolution of the physical processes that are developed. Relationships between the
concentrations of the different bioaerosols will be established with the meteorological variables, and special emphasis will be placed on
periods of extreme events. In addition, trends in pollen and spore time series, dating to 1994, will be analyzed and related to changes in
weather patterns and other environmental changes. This will improve the understanding of the relationship between extreme events of
temperature and precipitation and biological elements and will advance the knowledge of the impact of meteorology on the plant landscape
(pollination / sporulation trends) and the health of people and animals (Allergies) and plants (pathologies and pests) and on the biological
cycles of microarthropods.
3) The development and validation of an operational model for the forecast of aerobiological contaminants. Based on the previous
knowledge on biological and meteorological mechanisms that control the emissions and dispersion of pollen, spores and allergens in the
atmosphere and with the purpose of creating a bioparticle transport model, it is proposed to provide the chemical transport model NMMB
/BSC-CTM of a real-time forecast and diagnosis module for pollen. The model will be evaluated based on aerobiological observations with
hourly resolution as well as sophisticated laser scanning techniques (LIDAR) that provide information on the vertical profile and the
physical properties of pollen. The execution of TECBIOMET will thus benefit from the use of consolidated modeling techniques that are
successfully applied in atmospheric chemistry for gases and aerosols, but which have not been applied in the Spanish territory until now,
to the emission, transport and forecast of pollen levels.
The potential use of the results that will be obtained is thus very large and therefore, within the framework of the project, promotion
activities will be promoted, purely scientific and those of a more informative nature.
