Canopy temperature dynamics are closely aligned with ecosystem water availability across a water- to energy-limited gradient

This research would not have been possible without the technical support of J. Wang and J. Smith at USDA-ARS, who played key roles in the installation and maintenance of the Bigelow and Kendall thermal cameras. We also thank the three anonymous reviewers whose feedback helped to improve the clarity of the manuscript.
