Herein, an investigation of the representativeness of pollen concentrations was performed for 20 pollen types in the pollen seasons 2015¨C2016 in Vienna for rooftop and ground level and was compared with weather data and for the first time with symptom data %K Symptom data %K Sampling height %K Pollen concentrations %K Computational methods ZAMG %K Zentralanstalt f¨¹r Meteorologie und Geodynamik %K PHD %K Patient's Hayfever Diary %K SLI %K Symptom load index %K SOM %K Self Organizing Map %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6514368/
