Figure 3.34. Airborne grass pollen as registered in a Burkard volumetric spore trap at SU/Östra sjukhuset, Gothenburg. The total pollen amount was positively related to the minimum temperature in April (R2=0.27; Prob>ChiSq =0.0014). Multiple regressions - Total pollen amount Figure 3.36. Airborne grass pollen as registered in a Burkard volumetric spore trap at SU/Östra sjukhuset, Gothenburg. The Figure 2.7 Explanatory power of combined meteorological total pollen amount was positively related to the annual variables on the total pollen amount. Mean temperature of April precipitation (R2=0.23; Prob>ChiSq =0.0031). and precipitation in March provide the best explanation. Figure 3.38.
