Short summary
There currently is no standardized approach for measuring dew formation, making it difficult to compare its frequency and importance across ecosystems. Recently, canopy surface temperature data from 30 sites in the US were measured continuously using in situ infrared radiometers. The analysis presented here provides the first continental-scale standardized synthesis of dew formation. This work provides a basis for considering how changing climate and land use will influence dew formation.
