Au-Wom Wombat Forest #eddycovariance tower spring clean and check ups. No water ingress in this anemometer 😃 And no damage from the storm on Wednesday, only one tree down in the plot. The DIY Lora #dendrometers survived winter too - mostly.

Spring cleaning and maintenance trip to Au-Tum Tumbarumba this week! It got a bit wet and foggy up there 😐. But a good trip anyway! #flux data analysis for the year so far resulted in some interesting challenges too. #eddycovariance #unimelb #tern #tern

Check ups, and updates at some of my #eddycovariance #fluxtowers, big and small, this week. Data coming in nicely. #ozflux

Good news! We installed a new #eddycovariance flux tower this week during a too short trip to the outback. This time we're monitoring salt bush vegetation. It is a fantastic opportunity to work in an arid landscape. Seemingly endless plains, great scenery, and ever changing colours. #ozflux

Alpine forests face collapse after bushfires and lack of seeds
www.abc.net.au/news/2025-06...
Alpine forests face collapse without urgent reforestation, say scientists
Bushfires and a lack of seed have created a "ticking time bomb" in Victoria's alpine and mountain ash forests, scientists are warning.

After the recent redesign /rebuild and upgrade of the Au-Whr Whroo flux tower to prevent further theft and vandalism, we now reinstalled a mixture of old and new soil sensors. #eddycovariance

Excited to share our new paper led by Tsinghua Uni ECR Zhang Han: www.science.org/doi/10.1126/.... New model based on eco-evolutionary optimality explains observed seasonal and spatial trends in stem respiration, implies stem CO2 efflux down by >25% by 2100, reducing land carbon emissions.
Thermal acclimation of stem respiration implies a weaker carbon-climate feedback
The efflux of carbon dioxide (CO2) from woody stems, a proxy for stem respiration, is a critical carbon flux from ecosystems to the atmosphere, which increases with temperature on short timescales. Ho...

Three #eddycovariance towers in three days. Moved one, added two. These little towers are part of a long term agricultural trial.

Backyard eddycovariance tower 😉. I set up a system at home over the Easter holidays to tweak, test, and monitor the setup. Let's find out if my backyard is a carbon sink or source. Science at home 👍

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.
