Behavior of the SLI data and the pollen data as square root of the respective aeroallergen is displayed. a, Linear regression (grey) and LOESS curve (black) in the three areas within Vienna and the Pannonian Lowlands for the respective pollen seasons (2013–2017) of alder (upper), birch (middle) and grass (lower). Note the similar behavior of the LOESS for all areas/regions within the same pollen season. b, Temporal development of square root of the daily pollen concentrations (grey) and the respective SLI data (black). The birch pollen season 2014 (upper) and the grass pollen season 2014 (lower) were chosen as examples to show the similar progress of the datasets. Peaks of the pollen data are reflected in the SLI data
