Figure 8.

Linear regressions (blue lines) between LFU PoMo and Hirst-type main pollen season traits are shown, with 95% confidence intervals (grey area). The coefficient of determination (R²) and Pearson’s correlation coefficient (r) are also shown. (A) The pollen season length (duration between the first and the last pollen day). (B) The Annual Pollen Integral (cumulative pollen concentration per year). (C) Peak daily pollen concentration (maximum concentration per year). (D) Date on which the maximum concentration per year was observed. (E) The date on which the first pollen was observed in the year. (F) The date on which the last pollen was observed in the year.
