Study of the meteorological mechanisms controlling levels and transport processes of airborne pollen in the atmosphere
Aerobiology is the science that focuses on the study of the airborne living organisms (bacteria, fungal spores, pollen, small insects, etc.). The influence of meteorology and climate change on plant phenology include shifts in the timing of the pollination seasons or an increase of the pollen produc...

Aerobiology is the science that focuses on the study of the airborne living organisms (bacteria, fungal spores, pollen, small insects, etc.). The influence of meteorology and climate change on plant phenology include shifts in the timing of the pollination seasons or an increase of the pollen production of different plants. The present study explores the role of meteorological variability in the pollen dynamics. The main standardized pollen parameters (Annual Pollen Integral (APIn), Start, End and Length of the main pollen season) of 22 taxa collected by the Xarxa Aerobiològica de Catalunya (XAC) at 6 stations in Catalonia (Barcelona (BCN), Bellaterra (BTU), Girona (GIC), Lleida (LLE), Manresa (MAN) and Tarragona (TAU)) during the 18-year period from 1994 to 2011, have been considered. Correlations between precipitation, insolation and temperature and the main pollen parameters have been investigated.
