Highlights

  • The USA-NPN’s flower and pollen cone observations could address gaps in pollen monitoring.
  • Significant correlations were found between volunteer-contributed observations and airborne pollen concentrations for 15 common tree taxa.
  • A formal observation campaign could further enhance the quantity and utility of these data.

Observations from the USA National Phenology Network can be leveraged to model airborne pollen

Highlights

  • The USA-NPN hosts the largest volunteer-contributed plant phenology dataset in the US.
  • Winter-spring temperatures predicted the flowering time of oak trees.
  • Predicted peak flowering was strongly correlated with peak airborne pollen concentrations.
  • The USA-NPN dataset has significant potential for improving source-based models of airborne pollen.
