U.S. National Phenology Network Citizen Contributions to Atmospheric Science Research

Decades of spring lilac phenological data (collected by citizen scientists across much of North America) have facilitated models which simulate growing season onset in many temperate climates. These models have provided insights into seasonal land surface/lower atmosphere energy/mass exchange variations, and clarified the role of large-scale circulation changes in modifying the onset of “spring”. Full development of the USA National Phenology Network will add to these research contributions.
