Short summary
A new parameterization, Pollen Emissions for Climate Models (PECM), has been developed for use in climate models. New developments include (1) a new climate-sensitive, observation-based phenological model, (2) inclusion of the 13 highest-pollinating taxa in the United States, and (3) an option to compute pollen emissions by plant functional type (PFT). It can be used to address topics like impacts of climate change (e.g., on allergen exposure, on plant ecology) or pollen as an atmospheric aerosol.
