New paper: Land-atmosphere feedbacks and information flows
This was a fun paper to do. It is nice to explore some new and innovative methods to understand and quantify land-atmosphere feedback: Information Flows.
We can use the wealth of FLUXNET data to find hotspots of coupling.

Editorial Summary
“Big data” methods reveal robust hotspots of land–atmosphere coupling. Sparse observations and inadequate analytical tools have hindered our understanding of land–atmosphere feedbacks, including the exchange of energy, water, and CO2. Emergent methods such as machine learning, however, offer new opportunities, as Tobias Gerken from Montana State University, USA, and colleagues, demonstrate. A “big data” approach is adopted to characterise the spatial and temporal variability of land–atmosphere coupling without a priori assumptions: information flows are computed from 251 FLUXNET sites which are subsequently used to train a neural network. Distinct regional differences in the magnitude of land–atmosphere feedbacks are found, related to climatic zone and biome type; coupling in semi-arid ecosystems, for example, are strongly related to seasonal water availability. Complementing model studies with such empirical approaches may assist in quantifying climate change impacts on ecosystem services.
The natural journals the kids were working on turned out well. We began the natural journal project by finding beauties in nature in fall. Now that they are together, we will fill them with writings and drawings about what we observe while in our sit spot this winter using this excerpt from beautiful poem from Walt Whitman as an inspiration:
There was a child went forth everyday,
And the first…
Oh my, the kids are just loving making our own nature journals. Both my children (my son especially) likes drawing and nature journaling, but we have never before made our own journals. We are starting by collecting things from Mother Earth that inspire us. Lots more to do, but this will be a great tool for when we start exploring animal allies this winter.
