New Tansley review paper from Zoe Pierrat & friends in @newphyt.bsky.social linking proximal remote sensing with ecosystem fluxes!

Synergies and best practices for hyperspectral reflectance, SIF, thermal, microwave and lidar 🌈🌲🗼🛰️🧪
nph.onlinelibrary.wiley.com/doi/10.1111/...
Overview of proximal remote sensing instruments at a flux tower site. Shown are three eddy-covariance towers with sonic anemometers collecting data to derive ecosystem fluxes. Shown for spectral reflectance and solar-induced fluorescence (SIF) is a hyperspectral sensor with a narrow field-of-view (FOV) and multi-directional scanning capabilities (Sections II.1 and II.2). We also show the direct emission of SIF from the forest canopy (Section II.2). For thermal infrared radiation, we show a fixed thermal camera and thermal radiation coming from the canopy (Section II.3). For microwave, we show two potential arrangements with antenna A receiving direct signals from under open-sky conditions as well as signals that are reflected from the underlying vegetated surface, and antenna B receiving a direct signal that is propagated downward through the vegetation canopy and attenuated by its moisture content (Section II.4). We also show a light detection and ranging (LiDAR) instrument emitting light to get a 3D representation of canopy structure (Section II.5). Above the forest are a drone, aircraft, and satellite to emphasize the potential of proximal remote sensing to complement observations across scales. In the inset plot, we show sample reflectance spectra for vegetation and wet soil and highlight key wavelength ranges for spectral reflectance. We also show typical SIF retrieval windows and LiDAR emission windows. Next to the reflectance spectra, we show sample radiance in the thermal infrared region, with example spectra for warm soil and cool vegetation. Finally, we show key measurement wavelength bands for microwave backscatter.

Little Christmas surprise: check out our new paper out in @newphyt.bsky.social, we investigated nutrient release dynamics in wood. Takeaways: what is known from leaf litter does not apply to wood! Time to consider wood and their decomposers different to those of leaf litter. doi.org/10.1111/nph....
Faster than expected: release of nitrogen and phosphorus from decomposing woody litter
Deadwood represents globally important carbon (C), nitrogen (N), and phosphorus (P) pools. Current wood nutrient dynamics models are extensions of those developed for leaf litter decomposition. Howe.....

New pub in Earth Future. We showed increasing flooding events are NOT as much as rainfall increase. Why? Plants are helping us.

Scientists are expected to do peer reviewing but no one tells you HOW. After talking with several folks about this today at #AGU24 , it seems a good time to link to this presentation I made several years ago -- feel free to use/share! docs.google.com/presentation...
