Simulated leaf (green trace in top panel) temperature from an Apogee model SF-110 compared to air

temperature (black trace in top panel) and simulated bud (blue trace in top panel) temperature throughout a

clear (net longwave radiation is plotted in middle panel), calm (wind speed is plotted in bottom panel) night

during spring in Logan, Utah. Simulated leaf temperatures reached the freezing point approximately 5.5 hours

before air temperature.
