The impact of ecosystem nitrogen enrichment on pollen allergy: a cross-sectional paired comparison study
cross-sectional studies Ecosystem Female Grassland Humans Immunoglobulin E Male middle aged Nitrogen pollen Rhinitis, Allergic, Seasonal Abstract: BACKGROUND: The prevalence of allergy to aeroallergens is rising, ...
What drives the long-term changes in airborne birch and grass pollen levels in Belgium?
birch pollen and ~15% to grass pollen. Future climate and land-use changes may exacerbate this issue by increasing the amount of allergenic pollen in the air and prolonging pollen seasons. This study aims ...
Analyzing the airborne birch and grass pollen monitoring network in Belgium
mode (three days), determining the trajectory of birch and grass pollen observed at the network stations. Nine pollen seasons (2013–2021) were analyzed using ECMWF ERA5 meteorology. Results The network ...
Estimating the Uncertainty in Airborne Birch Pollen Modelling
Methods The uncertainty in modelling airborne birch pollen levels near the surface using SILAM is quantified based on a Monte-Carlo error approach for the season of 2018 in Belgium using varying major model ...
Evaluation of European Pollen Reanalysis
the total seasonal pollen production, i.e. the phenological models and their parameters were left completely intact. This allowed an almost-complete separation of the absolute values of the predicted ...
First European pollen reanalysis for allergenic trees
source modules. The pollen season onset and its following propagation were reproduced based on the model internal formulations only. The corrections to the mean pollen productivity were introduced by ...
Modelling grass pollen load in temperate and Mediterranean European areas based on source spatial distribution
KC; Nicolas Bruffaerts; Buters J Source: World Aerobiology Conference 2024, University of Vilnius, Vilnius, Lithuania (2024) Keywords: pollen Abstract: Airborne grass pollen is one of the most important ...
Holography-based aerobiological monitoring: a 2-year intercomparison campaign versus the standard Hirst method in Brussels, Belgium
Betula, Fraxinus and Poaceae. While some pollen taxa showed similar seasonal kinetics but with scaling discrepancies, other pollen taxa frequently presented out-of-season false positive peaks as results ...
The search for the best airborne pollen monitoring locations
RMSE computed from the reference concentration field and the interpolated concentration field for each day of the pollen season. In the first step, time series of the current daily pollen observations in ...
Effects of tree pollen on throughfall element fluxes in European forests
can lead to misinterpretations of element deposition in European forests. We investigated the relationship between forest throughfall (TF) element fluxes and the Seasonal Pollen Integral (SPI n) using ...
