• Andrew presented results from the first year of PhenoCam data at the SPRUCE experiment in the phenology session at the AGU Fall Meeting in San Francisco. As always, it was great to see old friends (including Markus Reichstein, Paul Stoy, Dario Papale, Dave Moore, & Rodrigo Vargas) and former lab members (Trevor Keenan, Youngryel Ryu, and Min Chen)! Andrew and Rodrigo snapped their annual photo with President Margaret Leinen.
