Highlights
We aimed to deliver near-term forecasts of vegetative and reproductive phenology of wind-pollinated plants that induce allergy.
We leveraged diverse phenology data including remote sensing, phenophase observations, and airborne pollen concentrations.
We used spatiotemporal Gaussian Process Empirical Dynamic Modelign (GPEDM) to forecast maps of phenology in the continental US.
We implemented infrastructure to deliver forecasts every day for the following 35 days on our web app, PhenoForecast.
Background
Synthesizing phenology data from multiple sources.
Methods
Infrastructure to collect data, fit models, make predictions, and deliver forecasts.
Four levels of the model behind PhenoForecast and key data sources.
Steps in each level of the model.

Evaluation
Correlation between observed and predicted EVI.
Fitted and forecasted EVI at six randomly selected sites. Black lines show observations; blue lines and ribbons show predictions with 95% intervals.
