Causes of widespread foliar damage from the June 2021 Pacific Northwest Heat Dome: more heat than drought.

Graph: Figure 3 (A) Time series of leaf temperature data (dashed line) that were extracted from the thermal images of a foliage-dominated region of interest along with air temperature data from an aspirated temperature sensor in a radiation shield located at the same height (56 m aboveground) in the upper-canopy of a Douglas-fir tree at the HJ Andrews experimental Forest near Blue River, Oregon.
