Abstract

The AA. explore a new-phenology-based strategy for evaluating the spring surface energy-balance shift. Their technique can reflect native-species responses and atmospheric surface layer change at a variety of sites, using synoptic-scale first leaf and first bloom phenology models. The AA. test the approach at 3 locations with diverse climates, and within a group of stations in the state of Oklahoma, which has moderate climate variations across an east-to-west gradient. The resuls show that the onset of spring in midlatitudes is a modally abrupt (rather than gradual) seasonal transition in terms of energy balance and carbon-flux change that can be linked directly to vegetation phenology
