Bayesian analysis of climate change effects on observed and projected airborne levels of birch pollen
چکیده انگلیسی

A Bayesian framework is presented for modeling effects of climate change on pollen indices such as annual birch pollen count, maximum daily birch pollen count, start date of birch pollen season and the date of maximum daily birch pollen count. Annual mean CO2 concentration, mean spring temperature and the corresponding pollen index of prior year were found to be statistically significant accounting for effects of climate change on four pollen indices. Results suggest that annual productions and peak values from 2020 to 2100 under different scenarios will be 1.3–8.0 and 1.1–7.3 times higher respectively than the mean values for 2000, and start and peak dates will occur around two to four weeks earlier. These results have been partly confirmed by the available historical data. As a demonstration, the emission profiles in future years were generated by incorporating the predicted pollen indices into an existing emission model.


► A Bayesian framework is presented to model climate change effect on birch pollen.
► Airborne pollen levels are estimated based on observed and projected climate factors.
► Pollen emission fluxes are generated using the output from Bayesian model.
► Pollen season tends to start earlier with rising airborne pollen levels in the future.
