“…e impact of meteorological conditions on daily pollen concentration is very complex as many factors may act differently on airborne pollen level. In general, it has been however shown that an increase in daily air temperature oen correlates positively with higher concentrations of airborne pollen grains in most allergenic taxa (Borycka & Kasprzyk, 2014;Dąbrowska-Zapart et al, 2018;Dąbrowska-Zapart & Niedźwiedź, 2020;Grewling et al, 2019b;Kubik-Komar et al, 2018;Weryszko-Chmielewska et al, 2006). On the other hand, rainfall (recorded during the pollen season) oen decreases pollen concentrations in the air, potentially due to the "washout" effect.…”

Aerobiology is a scientific discipline that focuses on investigating biological particles (bioaerosols) passively transported in the atmosphere, mainly fungal spores and pollen grains. Due to the allergic and pathogenic properties of these particles, aerobiological data is widely used in allergology, plant pathology, and agriculture. In addition, the results of aerobiological monitoring have found applications in biogeography, paleoecology, forestry, veterinary medicine, forensic science, and climate change research, as well as in the assessment of threats to the deterioration of cultural heritage. In this review, the contribution of Polish scientists to the development of worldwide aerobiology is presented. The most important results on the atmospheric dispersion of bioaerosols, spatiotemporal modeling, and novel methods used in aerobiological research are described. Moreover, the cooperation at the national and international levels as part of scientific programs and the perspectives for further development of aerobiology in Poland are discussed.

“…The effect of wind direction on the clustering pattern was studied by circular statistics (Sadyś et al, 2015, Borycka and Kasprzyk, 2014, Maya-Manzano et al, 2017. The circular average of the prevalent wind direction was calculated for the days associated with each cluster.…”

Cluster analysis of variations in the diurnal pattern of grass pollen concentrations in Northern Europe (Copenhagen) and Southern Europe (Cordoba)

From an allergological point of view, Poaceae pollen is one of the most important type of pollen that the population is exposed to in the ambient environment. There are several studies on intradiurnal patterns in grass pollen concentrations, and agreement on the high variability. However, the method for analysing the different patterns is not yet well established. The aim of the present study is therefore to examine the method of pattern analysis by statistical clustering, as well as relating the proposed patterns to time of season and meteorological variables at two highly different biogeographical locations; Córdoba, Spain and Copenhagen, Denmark.Airborne pollen is collected by Hirst type volumetric spore traps and counted using an optical microscope at both sites. The counts were converted to two-hours concentrations and a new method based on cluster analysis was applied with the aim of determining the most frequent diurnal patterns in pollen concentrations and their dependencies of site, season and meteorological variables.Three different well defined diurnal patterns were identified at both locations. The most frequent pattern in Copenhagen was associated with days having peak pollen concentrations in the evening (maximum between18h-20h), whereas the most frequent pattern at Córdoba was associated with days having peak pollen concentrations in the afternoon (maximum between 14h-16h). These three patterns account for 70% of days with no rain and pollen concentrations above 20 grains m -3 . The most frequent pattern accounts for 40% and 57% of the days in Córdoba and Copenhagen respectively. The analysis clearly shows the great variation in pollen concentration pattern, albeit a dominating pattern can be found.It was not possible to explain all the differences in the patterns by the meteorological variables when examined individual. Clustering method is estimated to be an appropriate methodology for studying aerobiological phenomena with high variability.
