#bikepacking weekend in the Victorian Pyrenees. Nice getaway in a beautiful area.

Panorama view from Au-Wom showing parts of the #eddycovariance system

Good conditions for work on Au-Wom #eddycovariance tower. Completed the profile system. Data look good so far 😃

Sun rays shining through the trees over a track in Wombat Forest

Rays of sunlight poking through the trees on a smokey day in Wombat Forest. The smoke is from the Carlisle / Otways bushfire more than 100 km away. Eerie day working in the haze.

📡 Margaret Torn, Director of the AmeriFlux Management Program, announced the soft launch of the FluxNet Shuttle, incorporating 9 TERN/OzFlux sites. Aggregation of TERN #data into FluxNet is vital for broader #datadelivery.

Data for the first night of Au-Wom CO2 profile measurements

Irgason and storage system gas inlet on the Au-Whr tower above the canopy

Upgraded the Au-Whr and Au-Wom towers with profile systems in the last two weeks. The data make beautiful lines so far 😃 #eddycovariance #ozflux @unimelb.bsky.social

Diy lora / data logger for dendrometer

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.

The Tumbarumba #flux tower in the #fog.

Nothing much to see from the tower looking at the surrounding forest in the #drizzle and #fog

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

Eddycovariance equipment above the forest

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

Eddycovariance flux tower in a saltbush landscape

Sunset and rainclouds in the saltbush plains

Heading towards the sunset after a ten+ hours trip

Perfect location for a small #eddycovariance tower: flat in all directions!

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

Had a great time at the #fluxnet 2025 conference @fluxnet.bsky.social Great people, new ideas, new challenges. 😃

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.

That would have been great for me a few years ago... #clot

Au-Whr Whroo eddy covariance tower

View from the top over the canopy of the Whroo nature reserve

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

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...

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.

Great to see that the beloved red gondola is still going strong at KROFF! #memories #casiroz

Setting up the next eddycovariance tower in the experiment

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

Forest productivity response to elevated CO2 in free‐air CO2 enrichment experiments: the 23 percent solution, revisited A synthesis of free-air CO2 enrichment (FACE) experiments describing the response of forest net primary productivity (NPP) to elevated atmospheric CO2 published in 2005 has provided a valuable benchm...

Eddycovariance test system in my backyard for testing at home

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 👍

The Wombat Forest flux tower

Planned burn turned into a bushfire not far from the tower. Smoke and clouds visible

#Fieldwork on AU-Wom Wombat Forest #eddycovariance flux tower today when a planned burn in the distance got a bit out of hand

Early stages of building three new #eddycovariance systems in the lab

Preparation of the next three #fluxtowers has started 😀. #newgearday. Hope they'll be deployed before winter.

The Tumbarumba eddycovariance flux tower

Profile systems for CO2, H2O, and wind

Rigging works

Used more than a kilometre of cables and tubes for the install of the profile system

Another big week at the Au-Tum Tumbarumba flux tower: Installed a profile system to improve the #eddycovariance measurements.

Good bye Twitter! 😥
HELLO BLUESKY!!! 😀

Vertical canopy gradients of respiration drive plant carbon budgets and leaf area index Despite its importance for determining global carbon fluxes, leaf respiration remains poorly constrained in land surface models (LSMs). We tested the sensitivity of the Energy Exascale Earth System ...

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.
