Jen and Andrew are coauthors on a new paper out in PNAS, “Cooling outweighs warming across phenological transitions in the Northern Hemisphere”. Led by collaborator Lin Meng and her student Yizhuo Li at Vanderbilt, the paper shows that vegetation exerts a dominant surface cooling effect during phenological transitions in mid- to high-latitude forests, with amplified cooling under climate warming in many regions. Andrew’s PhenoCam data were used to identify phenological transition dates at 17 AmeriFlux sites, and Jen analyzed long-wave radiation data from those tower sites to develop a land surface temperature dataset used to ground-truth patterns that had been initially identified from satellite remote sensing.
