2020: THE REST OF THE YEAR….

It’s hard to come up with a list of “news” during this incredibly difficult and challenging time. We are all working from home (thank you, computational research), meeting online, and trying to stay healthy and sane. I have been amazed at the work that everyone in the group has been able to accomplish under the new normal. And good things have been happening: papers and proposals are getting submitted, and we keep trying to understand how we can do research and keep moving on during this challenging time. And there are some bright spots:

  • Former grad student Matthew Wozniak (now a postdoc at Princeton) has has final dissertation chapter online, titled Influence of vertical heterogeneities in the canopy microenvironment on inter-annual variability of carbon uptake in temperate deciduous forests . Check out Figure 7, which shows how even multi-layer canopies can struggle to capture observed diffuse light.
  • We are part of the Department of Energy’s Science Team for the new AMF3 deployment in the Southeastern US. Stay tuned for more updates about the site and how it will be selected.
